PHP convert XML to JSON
I am trying to convert xml to json in php. If I do a simple convert using simple xml and json_encode none of the attributes in the xml show.
$xml = simplexml_load_file("states.xml");
echo json_encode($xml);
So I am trying to manually parse it like this.
foreach($xml->children() as $state)
{
$states= array('state' => $state->name);
}
echo json_encode($states);
and the output for state is {"state":{"0":"Alabama"}} rather than {"state":"Alabama"}
What am I doing wrong?
XML:
<?xml version="1.0" ?>
<states>
<state id="AL">
<name>Alabama</name>
</state>
<state id="AK">
<name>Alaska</name>
</state>
</states>
Output:
[{"state":{"0":"Alabama"}},{"state":{"0":"Alaska"}
var dump:
object(SimpleXMLElement)#1 (1) {
["state"]=>
array(2) {
[0]=>
object(SimpleXMLElement)#3 (2) {
["@attributes"]=>
array(1) {
["id"]=>
string(2) "AL"
}
["name"]=>
string(7) "Alabama"
}
[1]=>

This is exactly what I was looking for, however I think the question wanted special parsing. Taking certain sub-elements and moving them up the tree ( a custom parser ), instead of a 1 to 1 conversion.

@JakeWilson maybe it's the 2 years that have passed, and various version fixes, but on PHP 5.6.30, this method produces ALL of the data. Attributes are stored in the array under the@attributeskey, so it works absolutely flawlessly, and beautifully. 3 short lines of code solve my problem beautifully.

Sorry for answering an old post, but this article outlines an approach that is relatively short, concise and easy to maintain. I tested it myself and works pretty well.
http://lostechies.com/seanbiefeld/2011/10/21/simple-xml-to-json-with-php/
<?php
class XmlToJson {
public function Parse ($url) {
$fileContents= file_get_contents($url);
$fileContents = str_replace(array("n", "r", "t"), '', $fileContents);
$fileContents = trim(str_replace('"', "'", $fileContents));
$simpleXml = simplexml_load_string($fileContents);
$json = json_encode($simpleXml);
return $json;
}
}

This will not work if you have multiple instances of the same tag in your XML, json_encode will end up only serializing the last instance of the tag.

I figured it out. json_encode handles objects differently than strings. I cast the object to a string and it works now.
foreach($xml->children() as $state)
{
$states= array('state' => (string)$state->name);
}
echo json_encode($states);

I guess I'm a bit late to the party but I have written a small function to accomplish this task. It also takes care of attributes, text content and even if multiple nodes with the same node-name are siblings.
Dislaimer:
I'm not a PHP native, so please bear with simple mistakes.
function xml2js($xmlnode) {
$root = (func_num_args() > 1 ? false : true);
$jsnode = array();
if (!$root) {
if (count($xmlnode->attributes()) > 0){
$jsnode["$"] = array();
foreach($xmlnode->attributes() as $key => $value)
$jsnode["$"][$key] = (string)$value;
}
$textcontent = trim((string)$xmlnode);
if (count($textcontent) > 0)
$jsnode["_"] = $textcontent;
foreach ($xmlnode->children() as $childxmlnode) {
$childname = $childxmlnode->getName();
if (!array_key_exists($childname, $jsnode))
$jsnode[$childname] = array();
array_push($jsnode[$childname], xml2js($childxmlnode, true));
}
return $jsnode;
} else {
$nodename = $xmlnode->getName();
$jsnode[$nodename] = array();
array_push($jsnode[$nodename], xml2js($xmlnode, true));
return json_encode($jsnode);
}
}
Usage example:
$xml = simplexml_load_file("myfile.xml");
echo xml2js($xml);
Example Input (myfile.xml):
<family name="Johnson">
<child name="John" age="5">
<toy status="old">Trooper</toy>
<toy status="old">Ultrablock</toy>
<toy status="new">Bike</toy>
</child>
</family>
Example output:
{"family":[{"$":{"name":"Johnson"},"child":[{"$":{"name":"John","age":"5"},"toy":[{"$":{"status":"old"},"_":"Trooper"},{"$":{"status":"old"},"_":"Ultrablock"},{"$":{"status":"new"},"_":"Bike"}]}]}]}
Pretty printed:
{
"family" : [{
"$" : {
"name" : "Johnson"
},
"child" : [{
"$" : {
"name" : "John",
"age" : "5"
},
"toy" : [{
"$" : {
"status" : "old"
},
"_" : "Trooper"
}, {
"$" : {
"status" : "old"
},
"_" : "Ultrablock"
}, {
"$" : {
"status" : "new"
},
"_" : "Bike"
}
]
}
]
}
]
}
Quirks to keep in mind:
Several tags with the same tagname can be siblings. Other solutions will most likely drop all but the last sibling. To avoid this each and every single node, even if it only has one child, is an array which hold an object for each instance of the tagname. (See multiple "" elements in example)
Even the root element, of which only one should exist in a valid XML document is stored as array with an object of the instance, just to have a consistent data structure.
To be able to distinguish between XML node content and XML attributes each objects attributes are stored in the "$" and the content in the "_" child.
Edit:
I forgot to show the output for your example input data
{
"states" : [{
"state" : [{
"$" : {
"id" : "AL"
},
"name" : [{
"_" : "Alabama"
}
]
}, {
"$" : {
"id" : "AK"
},
"name" : [{
"_" : "Alaska"
}
]
}
]
}
]
}

This solution is better because not discards XML attributes. See also why this complex structure is better than simplified ones, at xml.com/lpt/a/1658 (see "Semi-Structured XML").... Ops, for CDATA, as @txyoji suggested to flatten CDATA elements$xml = simplexml_load_file("myfile.xml",'SimpleXMLElement',LIBXML_NOCDATA);.

A common pitfall is to forget that json_encode() does not respect elements with a textvalue and attribute(s). It will choose one of those, meaning dataloss.
The function below solves that problem. If one decides to go for the json_encode/decode way, the following function is advised.
function json_prepare_xml($domNode) {
foreach($domNode->childNodes as $node) {
if($node->hasChildNodes()) {
json_prepare_xml($node);
} else {
if($domNode->hasAttributes() && strlen($domNode->nodeValue)){
$domNode->setAttribute("nodeValue", $node->textContent);
$node->nodeValue = "";
}
}
}
}
$dom = new DOMDocument();
$dom->loadXML( file_get_contents($xmlfile) );
json_prepare_xml($dom);
$sxml = simplexml_load_string( $dom->saveXML() );
$json = json_decode( json_encode( $sxml ) );
by doing so, <foo bar="3">Lorem</foo> will not end up as {"foo":"Lorem"} in your JSON.

Try to use this

// first approach
$Json = json_encode(simplexml_load_string($xml));
---------------- OR -----------------------
// second approach
$Json = json_encode(simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA));
echo $Json;

Optimizing Antonio Max answer:
$xmlfile = 'yourfile.xml';
$xmlparser = xml_parser_create();
// open a file and read data
$fp = fopen($xmlfile, 'r');
//9999999 is the length which fread stops to read.
$xmldata = fread($fp, 9999999);
// converting to XML
$xml = simplexml_load_string($xmldata, "SimpleXMLElement", LIBXML_NOCDATA);
// converting to JSON
$json = json_encode($xml);

I've used Miles Johnson's TypeConverter for this purpose. It's installable using Composer.
You could write something like this using it:
<?php
require 'vendor/autoload.php';
use mjohnsonutilityTypeConverter;
$xml = file_get_contents("file.xml");
$arr = TypeConverter::xmlToArray($xml, TypeConverter::XML_GROUP);
echo json_encode($arr);

This is an improvement of the most upvoted solution by Antonio Max, which also works with XML that has namespaces (by replacing the colon with an underscore). It also has some extra options (and does parse <person my-attribute='name'>John</person> correctly).
function parse_xml_into_array($xml_string, $options = array()) {
/*
DESCRIPTION:
- parse an XML string into an array
INPUT:
- $xml_string
- $options : associative array with any of these keys:
- 'flatten_cdata' : set to true to flatten CDATA elements
- 'use_objects' : set to true to parse into objects instead of associative arrays
- 'convert_booleans' : set to true to cast string values 'true' and 'false' into booleans
OUTPUT:
- associative array
*/
// Remove namespaces by replacing ":" with "_"
if (preg_match_all("|</([\w\-]+):([\w\-]+)>|", $xml_string, $matches, PREG_SET_ORDER)) {
foreach ($matches as $match) {
$xml_string = str_replace('<'. $match[1] .':'. $match[2], '<'. $match[1] .'_'. $match[2], $xml_string);
$xml_string = str_replace('</'. $match[1] .':'. $match[2], '</'. $match[1] .'_'. $match[2], $xml_string);
}
}
$output = json_decode(json_encode(@simplexml_load_string($xml_string, 'SimpleXMLElement', ($options['flatten_cdata'] ? LIBXML_NOCDATA : 0))), ($options['use_objects'] ? false : true));
// Cast string values "true" and "false" to booleans
if ($options['convert_booleans']) {
$bool = function(&$item, $key) {
if (in_array($item, array('true', 'TRUE', 'True'), true)) {
$item = true;
} elseif (in_array($item, array('false', 'FALSE', 'False'), true)) {
$item = false;
}
};
array_walk_recursive($output, $bool);
}
return $output;
}

One does not use Regex to parse XML, unless it's a simple XML with trivial structure and very predictable data. I can't stress enough how bad this solution is. This BREAKS DATA. Not to mention that it's incredibly slow (you parse with regex, and then you re-parse again?) and doesn't handle self-closing tags.
– AlexanderMP
Feb 7 '17 at 16:19
I don't think you really looked at the function. It doesn't use regex to do the actual parsing, only as a simple fix to deal with namespaces - which has been working for all my xml cases - and that it is working is the most important, rather than being "politically correct". You're welcome to improve it if you want, though!
– TheStoryCoder
Feb 13 '17 at 21:39
The fact that it has worked for you doesn't mean it's right. It's code like this that generates bugs that are immensely hard to diagnose, and generates exploits. I mean even looking superficially at XML specs on sites like this w3schools.com/xml/xml_elements.asp show a lot of reasons why this solution wouldn't work. Like I said, it fails to detect self-closing tags like<element/>, fails to address elements that start with, or contain underscores, which is allowed in XML. Fails to detect CDATA. And as I've said, it's SLOW. It's an O(n^2) complexity because of inner parsing.
– AlexanderMP
May 9 '17 at 17:41
The thing is that dealing with namespaces wasn't even asked here, and there are PROPER ways to deal with namespaces. Namespaces exist as a helpful construction, NOT to be parsed like that and turned into an abomination that won't be processed by any reasonable parser. And all you needed to do for that is not to create the contender for the prize of "slowest algorithm of 2016", but to do a bit of searching, to come up with a myriad of actual solutions, like this one stackoverflow.com/questions/16412047/… And to call this an improvement? Wow.

If you would like to only convert a specific part of the XML to JSON, you can use XPath to retrieve this and convert that to JSON.
<?php
$file = @file_get_contents($xml_File, FILE_TEXT);
$xml = new SimpleXMLElement($file);
$xml_Excerpt = @$xml->xpath('/states/state[@id="AL"]')[0]; // [0] gets the node
echo json_encode($xml_Excerpt);
?>
Please note that if you Xpath is incorrect, this will die with an error. So if you're debugging this through AJAX calls I recommend you log the response bodies as well.

Looks like the $state->name variable is holding an array. You can use
var_dump($state)
inside the foreach to test that.
If that's the case, you can change the line inside the foreach to
$states= array('state' => array_shift($state->name));
to correct it.

The question doesn't say it, but usually PHP is returning JSON to a web page.
I find it much easier to convert the XML to JSON in the browser/page via a JS lib, for example:

All solutions here have problems!
... When the representation need perfect XML interpretation (without problems with attributes) and to reproduce all text-tag-text-tag-text-... and order of tags. Also good remember here that JSON object "is an unordered set" (not repeat keys and the keys can't have predefined order)... Even ZF's xml2json is wrong (!) because not preserve exactly the XML structure.
All solutions here have problems with this simple XML,
<states x-x='1'>
<state y="123">Alabama</state>
My name is <b>John</b> Doe
<state>Alaska</state>
</states>
... @FTav solution seems better than 3-line solution, but also have little bug when tested with this XML.
Old solution is the best (for loss-less representation)
The solution, today well-known as jsonML, is used by Zorba project and others, and was first presented in ~2006 or ~2007, by (separately) Stephen McKamey and John Snelson.
// the core algorithm is the XSLT of the "jsonML conventions"
// see https://github.com/mckamey/jsonml
$xslt = 'https://raw.githubusercontent.com/mckamey/jsonml/master/jsonml.xslt';
$dom = new DOMDocument;
$dom->loadXML('
<states x-x='1'>
<state y="123">Alabama</state>
My name is <b>John</b> Doe
<state>Alaska</state>
</states>
');
if (!$dom) die("nERROR!");
$xslDoc = new DOMDocument();
$xslDoc->load($xslt);
$proc = new XSLTProcessor();
$proc->importStylesheet($xslDoc);
echo $proc->transformToXML($dom);
Produce
["states",{"x-x":"1"},
"nt ",
["state",{"y":"123"},"Alabama"],
"nttMy name is ",
["b","John"],
" Doent ",
["state","Alaska"],

Very unusual xml structure that I doubt would have real life use cases.

$xml = simplexml_load_string($xml_string);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
just add those three lines you will get the correct output:-)

After researching a little bit all of the answers, I came up with a solution that worked just fine with my JavaScript functions across browsers (Including consoles / Dev Tools) :
<?php
// PHP Version 7.2.1 (Windows 10 x86)
function json2xml( $domNode ) {
foreach( $domNode -> childNodes as $node) {
if ( $node -> hasChildNodes() ) { json2xml( $node ); }
else {
if ( $domNode -> hasAttributes() && strlen( $domNode -> nodeValue ) ) {
$domNode -> setAttribute( "nodeValue", $node -> textContent );
$node -> nodeValue = "";
}
}
}
}
function jsonOut( $file ) {
$dom = new DOMDocument();
$dom -> loadXML( file_get_contents( $file ) );
json2xml( $dom );
header( 'Content-Type: application/json' );
return str_replace( "@", "", json_encode( simplexml_load_string( $dom -> saveXML() ), JSON_PRETTY_PRINT ) );
}
$output = jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' );
echo( $output );
/*
Or simply
echo( jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' ) );
*/
?>
It basically creates a new DOMDocument, loads and XML file into it and traverses through each one of the nodes and children getting the data / parameters and exporting it into JSON without the annoying "@" signs.
Link to the XML file.

It is a small and universal solution based on an array of data can be a JSON transformed json_decode ...lucky

In what way does this answer the original question? Your answer seems more complicated than the original question, and also doesn't seem to even mention JSON anywhere.

Sorry, I uploaded the implementation is to respond to the conversion of XML to any understandable to process a simple PHP json_encode arrangement. Sorry for the lack of clarity

@JakeWilson maybe it's the 2 years that have passed, and various version fixes, but on PHP 5.6.30, this method produces ALL of the data. Attributes are stored in the array under the@attributeskey, so it works absolutely flawlessly, and beautifully. 3 short lines of code solve my problem beautifully.

I figured it out. json_encode handles objects differently than strings. I cast the object to a string and it works now.
foreach($xml->children() as $state)
{
$states= array('state' => (string)$state->name);
}
echo json_encode($states);

I guess I'm a bit late to the party but I have written a small function to accomplish this task. It also takes care of attributes, text content and even if multiple nodes with the same node-name are siblings.
Dislaimer:
I'm not a PHP native, so please bear with simple mistakes.
function xml2js($xmlnode) {
$root = (func_num_args() > 1 ? false : true);
$jsnode = array();
if (!$root) {
if (count($xmlnode->attributes()) > 0){
$jsnode["$"] = array();
foreach($xmlnode->attributes() as $key => $value)
$jsnode["$"][$key] = (string)$value;
}
$textcontent = trim((string)$xmlnode);
if (count($textcontent) > 0)
$jsnode["_"] = $textcontent;
foreach ($xmlnode->children() as $childxmlnode) {
$childname = $childxmlnode->getName();
if (!array_key_exists($childname, $jsnode))
$jsnode[$childname] = array();
array_push($jsnode[$childname], xml2js($childxmlnode, true));
}
return $jsnode;
} else {
$nodename = $xmlnode->getName();
$jsnode[$nodename] = array();
array_push($jsnode[$nodename], xml2js($xmlnode, true));
return json_encode($jsnode);
}
}
Usage example:
$xml = simplexml_load_file("myfile.xml");
echo xml2js($xml);
Example Input (myfile.xml):
<family name="Johnson">
<child name="John" age="5">
<toy status="old">Trooper</toy>
<toy status="old">Ultrablock</toy>
<toy status="new">Bike</toy>
</child>
</family>
Example output:
{"family":[{"$":{"name":"Johnson"},"child":[{"$":{"name":"John","age":"5"},"toy":[{"$":{"status":"old"},"_":"Trooper"},{"$":{"status":"old"},"_":"Ultrablock"},{"$":{"status":"new"},"_":"Bike"}]}]}]}
Pretty printed:
{
"family" : [{
"$" : {
"name" : "Johnson"
},
"child" : [{
"$" : {
"name" : "John",
"age" : "5"
},
"toy" : [{
"$" : {
"status" : "old"
},
"_" : "Trooper"
}, {
"$" : {
"status" : "old"
},
"_" : "Ultrablock"
}, {
"$" : {
"status" : "new"
},
"_" : "Bike"
}
]
}
]
}
]
}
Quirks to keep in mind:
Several tags with the same tagname can be siblings. Other solutions will most likely drop all but the last sibling. To avoid this each and every single node, even if it only has one child, is an array which hold an object for each instance of the tagname. (See multiple "" elements in example)
Even the root element, of which only one should exist in a valid XML document is stored as array with an object of the instance, just to have a consistent data structure.
To be able to distinguish between XML node content and XML attributes each objects attributes are stored in the "$" and the content in the "_" child.
Edit:
I forgot to show the output for your example input data
{
"states" : [{
"state" : [{
"$" : {
"id" : "AL"
},

Can it parse large XML data?
– Volatil3
Mar 1 '16 at 18:09
This solution is better because not discards XML attributes. See also why this complex structure is better than simplified ones, at xml.com/lpt/a/1658 (see "Semi-Structured XML").... Ops, for CDATA, as @txyoji suggested to flatten CDATA elements$xml = simplexml_load_file("myfile.xml",'SimpleXMLElement',LIBXML_NOCDATA);.

I guess I'm a bit late to the party but I have written a small function to accomplish this task. It also takes care of attributes, text content and even if multiple nodes with the same node-name are siblings.
Dislaimer:
I'm not a PHP native, so please bear with simple mistakes.
function xml2js($xmlnode) {
$root = (func_num_args() > 1 ? false : true);
$jsnode = array();
if (!$root) {
if (count($xmlnode->attributes()) > 0){
$jsnode["$"] = array();
foreach($xmlnode->attributes() as $key => $value)
$jsnode["$"][$key] = (string)$value;
}
$textcontent = trim((string)$xmlnode);
if (count($textcontent) > 0)
$jsnode["_"] = $textcontent;
foreach ($xmlnode->children() as $childxmlnode) {
$childname = $childxmlnode->getName();
if (!array_key_exists($childname, $jsnode))
$jsnode[$childname] = array();
array_push($jsnode[$childname], xml2js($childxmlnode, true));
}
return $jsnode;
} else {
$nodename = $xmlnode->getName();
$jsnode[$nodename] = array();
array_push($jsnode[$nodename], xml2js($xmlnode, true));
return json_encode($jsnode);
}
}
Usage example:
$xml = simplexml_load_file("myfile.xml");
echo xml2js($xml);
Example Input (myfile.xml):
<family name="Johnson">
<child name="John" age="5">
<toy status="old">Trooper</toy>
<toy status="old">Ultrablock</toy>
<toy status="new">Bike</toy>
</child>
</family>
Example output:
{"family":[{"$":{"name":"Johnson"},"child":[{"$":{"name":"John","age":"5"},"toy":[{"$":{"status":"old"},"_":"Trooper"},{"$":{"status":"old"},"_":"Ultrablock"},{"$":{"status":"new"},"_":"Bike"}]}]}]}
Pretty printed:
{
"family" : [{
"$" : {
"name" : "Johnson"
},
"child" : [{
"$" : {
"name" : "John",
"age" : "5"
},
"toy" : [{
"$" : {
"status" : "old"
},
"_" : "Trooper"
}, {
"$" : {
"status" : "old"
},
"_" : "Ultrablock"
}, {
"$" : {
"status" : "new"
},
"_" : "Bike"
}
]
}
]
}
]
}
Quirks to keep in mind:
Several tags with the same tagname can be siblings. Other solutions will most likely drop all but the last sibling. To avoid this each and every single node, even if it only has one child, is an array which hold an object for each instance of the tagname. (See multiple "" elements in example)
Even the root element, of which only one should exist in a valid XML document is stored as array with an object of the instance, just to have a consistent data structure.
To be able to distinguish between XML node content and XML attributes each objects attributes are stored in the "$" and the content in the "_" child.
Edit:
I forgot to show the output for your example input data
{
"states" : [{
"state" : [{
"$" : {
"id" : "AL"
},
"name" : [{
"_" : "Alabama"
}
]
}, {
"$" : {
"id" : "AK"
},
"name" : [{
"_" : "Alaska"
}
]
}
]
}
]
}

A common pitfall is to forget that json_encode() does not respect elements with a textvalue and attribute(s). It will choose one of those, meaning dataloss.
The function below solves that problem. If one decides to go for the json_encode/decode way, the following function is advised.
function json_prepare_xml($domNode) {
foreach($domNode->childNodes as $node) {
if($node->hasChildNodes()) {
json_prepare_xml($node);
} else {
if($domNode->hasAttributes() && strlen($domNode->nodeValue)){
$domNode->setAttribute("nodeValue", $node->textContent);
$node->nodeValue = "";
}
}
}
}
$dom = new DOMDocument();
$dom->loadXML( file_get_contents($xmlfile) );
json_prepare_xml($dom);
$sxml = simplexml_load_string( $dom->saveXML() );
$json = json_decode( json_encode( $sxml ) );
by doing so, <foo bar="3">Lorem</foo> will not end up as {"foo":"Lorem"} in your JSON.

Optimizing Antonio Max answer:
$xmlfile = 'yourfile.xml';
$xmlparser = xml_parser_create();
// open a file and read data
$fp = fopen($xmlfile, 'r');
//9999999 is the length which fread stops to read.

I used this approach, but JSON is empty. XML is valid.

I've used Miles Johnson's TypeConverter for this purpose. It's installable using Composer.
You could write something like this using it:
<?php
require 'vendor/autoload.php';
use mjohnsonutilityTypeConverter;
$xml = file_get_contents("file.xml");
$arr = TypeConverter::xmlToArray($xml, TypeConverter::XML_GROUP);
echo json_encode($arr);

This is an improvement of the most upvoted solution by Antonio Max, which also works with XML that has namespaces (by replacing the colon with an underscore). It also has some extra options (and does parse <person my-attribute='name'>John</person> correctly).
function parse_xml_into_array($xml_string, $options = array()) {
/*
DESCRIPTION:
- parse an XML string into an array
INPUT:
- $xml_string
- $options : associative array with any of these keys:
- 'flatten_cdata' : set to true to flatten CDATA elements
- 'use_objects' : set to true to parse into objects instead of associative arrays
- 'convert_booleans' : set to true to cast string values 'true' and 'false' into booleans
OUTPUT:
- associative array
*/
// Remove namespaces by replacing ":" with "_"
if (preg_match_all("|</([\w\-]+):([\w\-]+)>|", $xml_string, $matches, PREG_SET_ORDER)) {
foreach ($matches as $match) {
$xml_string = str_replace('<'. $match[1] .':'. $match[2], '<'. $match[1] .'_'. $match[2], $xml_string);
$xml_string = str_replace('</'. $match[1] .':'. $match[2], '</'. $match[1] .'_'. $match[2], $xml_string);
}
}
$output = json_decode(json_encode(@simplexml_load_string($xml_string, 'SimpleXMLElement', ($options['flatten_cdata'] ? LIBXML_NOCDATA : 0))), ($options['use_objects'] ? false : true));
// Cast string values "true" and "false" to booleans

One does not use Regex to parse XML, unless it's a simple XML with trivial structure and very predictable data. I can't stress enough how bad this solution is. This BREAKS DATA. Not to mention that it's incredibly slow (you parse with regex, and then you re-parse again?) and doesn't handle self-closing tags.

I don't think you really looked at the function. It doesn't use regex to do the actual parsing, only as a simple fix to deal with namespaces - which has been working for all my xml cases - and that it is working is the most important, rather than being "politically correct". You're welcome to improve it if you want, though!

Feb 13 '17 at 21:39
The fact that it has worked for you doesn't mean it's right. It's code like this that generates bugs that are immensely hard to diagnose, and generates exploits. I mean even looking superficially at XML specs on sites like this w3schools.com/xml/xml_elements.asp show a lot of reasons why this solution wouldn't work. Like I said, it fails to detect self-closing tags like<element/>, fails to address elements that start with, or contain underscores, which is allowed in XML. Fails to detect CDATA. And as I've said, it's SLOW. It's an O(n^2) complexity because of inner parsing.

The thing is that dealing with namespaces wasn't even asked here, and there are PROPER ways to deal with namespaces. Namespaces exist as a helpful construction, NOT to be parsed like that and turned into an abomination that won't be processed by any reasonable parser. And all you needed to do for that is not to create the contender for the prize of "slowest algorithm of 2016", but to do a bit of searching, to come up with a myriad of actual solutions, like this one stackoverflow.com/questions/16412047/… And to call this an improvement?

If you would like to only convert a specific part of the XML to JSON, you can use XPath to retrieve this and convert that to JSON.
<?php
$file = @file_get_contents($xml_File, FILE_TEXT);
$xml = new SimpleXMLElement($file);
$xml_Excerpt = @$xml->xpath('/states/state[@id="AL"]')[0]; // [0] gets the node
echo json_encode($xml_Excerpt);
?>
Please note that if you Xpath is incorrect, this will die with an error. So if you're debugging this through AJAX calls I recommend you log the response bodies as well.

Please note that if you Xpath is incorrect, this will die with an error. So if you're debugging this through AJAX calls I recommend you log the response bodies as well.

Looks like the $state->name variable is holding an array. You can use
var_dump($state)
inside the foreach to test that.
If that's the case, you can change the line inside the foreach to
$states= array('state' => array_shift($state->name));
to correct it.

The question doesn't say it, but usually PHP is returning JSON to a web page.
I find it much easier to convert the XML to JSON in the browser/page via a JS lib, for example:
https://code.google.com/p/x2js/downloads/detail?name=x2js-v1.1.3.zip

All solutions here have problems!
... When the representation need perfect XML interpretation (without problems with attributes) and to reproduce all text-tag-text-tag-text-... and order of tags. Also good remember here that JSON object "is an unordered set" (not repeat keys and the keys can't have predefined order)... Even ZF's xml2json is wrong (!) because not preserve exactly the XML structure.
All solutions here have problems with this simple XML,
<states x-x='1'>
<state y="123">Alabama</state>
My name is <b>John</b> Doe
<state>Alaska</state>
</states>
... @FTav solution seems better than 3-line solution, but also have little bug when tested with this XML.
Old solution is the best (for loss-less representation)
The solution, today well-known as jsonML, is used by Zorba project and others, and was first presented in ~2006 or ~2007, by (separately) Stephen McKamey and John Snelson.
// the core algorithm is the XSLT of the "jsonML conventions"
// see https://github.com/mckamey/jsonml
$xslt = 'https://raw.githubusercontent.com/mckamey/jsonml/master/jsonml.xslt';
$dom = new DOMDocument;
$dom->loadXML('
<states x-x='1'>
<state y="123">Alabama</state>
My name is <b>John</b> Doe
<state>Alaska</state>
</states>
');
if (!$dom) die("nERROR!");
$xslDoc = new DOMDocument();
$xslDoc->load($xslt);
$proc = new XSLTProcessor();
$proc->importStylesheet($xslDoc);
echo $proc->transformToXML($dom);
Produce
["states",{"x-x":"1"},
"nt ",
["state",{"y":"123"},"Alabama"],
"nttMy name is ",
["b","John"],
" Doent ",
["state","Alaska"],
"nt"
]
See http://jsonML.org or github.com/mckamey/jsonml. The production rules of this JSON are based on the element JSON-analog,
This syntax is a element definition and recurrence, with element-list ::= element ',' element-list | element.

After researching a little bit all of the answers, I came up with a solution that worked just fine with my JavaScript functions across browsers (Including consoles / Dev Tools) :
<?php
// PHP Version 7.2.1 (Windows 10 x86)
function json2xml( $domNode ) {
foreach( $domNode -> childNodes as $node) {
if ( $node -> hasChildNodes() ) { json2xml( $node ); }
else {
if ( $domNode -> hasAttributes() && strlen( $domNode -> nodeValue ) ) {
$domNode -> setAttribute( "nodeValue", $node -> textContent );
$node -> nodeValue = "";
}
}
}
}
function jsonOut( $file ) {
$dom = new DOMDocument();
$dom -> loadXML( file_get_contents( $file ) );
json2xml( $dom );
header( 'Content-Type: application/json' );
return str_replace( "@", "", json_encode( simplexml_load_string( $dom -> saveXML() ), JSON_PRETTY_PRINT ) );
}
$output = jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' );
echo( $output );
/*
Or simply
echo( jsonOut( 'https://boxelizer.com/assets/a1e10642e9294f39/b6f30987f0b66103.xml' ) );
*/
?>
It basically creates a new DOMDocument, loads and XML file into it and traverses through each one of the nodes and children getting the data / parameters and exporting it into JSON without the annoying "@" signs.
