I don't know of any direct APIs that can give you a result, but you can recursively print out each node and its attributes and then get your children and do the same.
Example -
def walker(root, str):
print(str+root.tag, (root.text and root.text.strip()) or '')
for attrib in root.attrib:
print(str+root.tag+'@'+attrib,root.attrib[attrib])
for child in root:
walker(child,str+root.tag+'/')
For xml as shown below -
>>> s = """<?xml version="1.0"?>
... <data>
... <country name="Liechtenstein">
... <rank>1</rank>
... <year>2008</year>
... <gdppc>141100</gdppc>
... <neighbor name="Austria" direction="E"/>
... <neighbor name="Switzerland" direction="W"/>
... </country>
... <country name="Singapore">
... <rank>4</rank>
... <year>2011</year>
... <gdppc>59900</gdppc>
... <neighbor name="Malaysia" direction="N"/>
... </country>
... <country name="Panama">
... <rank>68</rank>
... <year>2011</year>
... <gdppc>13600</gdppc>
... <neighbor name="Costa Rica" direction="W"/>
... <neighbor name="Colombia" direction="E"/>
... </country>
... </data>"""
>>>
>>>
>>> import xml.etree.ElementTree as ET
>>> r = ET.fromstring(s)
This gives me -
>>> walker(r,'/')
