Try these:

>>> from panXmlParser import c_panXmlParser
>>> data =3D '''<person>
.. <name>Jon</name>
.. <son><person>
..       <name>Fred</name>
..       <son>None</son>
..     </person> =20
.. </son>   =20
.. </person>
.. '''

>>> person =3D c_panXmlParser(data)

>>> person.son[0].person[0].name
['Fred']

>>> person.son[0].person[0].son
['None']


And these:

>>> data =3D '''<person>
.. <name>Jon</name>
.. <son>
..     <person>
..         <name>Fred</name>
..         <son>many</son>
..     </person> =20
..     <person>
..         <name>Pan</name>
..         <son>NotYet</son>
..     </person>       =20
.. </son>   =20
.. </person>
.. '''
..=20
>>> person =3D c_panXmlParser(data)

>>> person.son[0].person[0].name
['Fred']

>>> person.son[0].person[0].son
['many']

>>> person.son[0].person[1].name
['Pan']

>>> person.son[0].person[1].son
['NotYet']

>>> [x.name for x in person.son[0].person]
[['Fred'], ['Pan']]

>>> [x.son for x in person.son[0].person]
[['many'], ['NotYet']]
