Python: Convert XML to CSV file

I have an XML file like this:



<hierachy>
<att>
<Order>1</Order>
<attval>Data</attval>
<children>
<att>
<Order>1</Order>
<attval>Studyval</attval>
</att>
<att>
<Order>2</Order>
<attval>Site</attval>
</att>
</children>
</att>
<att>
<Order>2</Order>
<attval>Info</attval>
<children>
<att>
<Order>1</Order>
<attval>age</attval>
</att>
<att>
<Order>2</Order>
<attval>gender</attval>
</att>
</children>
</att>
</hierachy>


I'm trying to convert it to a CSV file like this:



Data,Studyval
Date,Site
Info,age
Info,gender


My problem is, both the parent and child names are the same- 'att' and 'attval'. How do I tell Python to distinguish between the both and give me the output?



I tried this:



import xml.etree.cElementTree as ET

tree = ET.parse('input.xml')
rebase = tree.getroot()

list =

for att in rebase.findall('att'):
name = att.find('attval').text
for each_att in att.findall('attval'):
try:
val = att.find('attval').text
print name, val
except AttributeError:
print name


and it printed the same things twice.

          Do not use the findall function, as it will look for att tags in the whole tree. Just iterate the tree in order from top to bottom and grab the relevant elements in them.



          from xml.etree import ElementTree
          tree = ElementTree.parse('input.xml')
          root = tree.getroot()

          for att in root:
          first = att.find('attval').text
          for subatt in att.find('children'):
          second = subatt.find('attval').text
          print('{},{}'.format(first, second))


          Which gives:



          $ python process.py 
          Data,Studyval
          Data,Site
          Info,age
          Info,gender
