This is from a class that is based on ParsedXML.ParsedXML, caveat: It's
code from an old project that isn't maintained and maybe it was done
suboptimal anyway :-)

def get_Status(self):
    doc = self.documentElement
    status = doc.getElementsByTagName('Status')[0].getAttribute('Number')
    return { 'Status':str(status), 'Schema':'ImageID' }

another one:

def get_photo_count(self):
    return self.documentElement.getElementsByTagName('Photo').length

the manage_addXY method of that object has something like this inside:

try:
    b = NetSelection(id, file, useNamespaces, contentType)
except expat.error, e:
    ... do things here

and the class has no explicit __init__ method, so likely we got that
from the ParsedXML.ParsedXML base class.

also there seems to be stuff that adds/changes things in some methods:
if not new_node:
    new_node = this_Photo.appendChild(doc.createElement(Network_Description))

or:
def _set_description_on_node ( self, node, Description_Dictionary ):
    ''' "sets" the contents of a Dictionary into an XML node '''
    for fred in Description_Dictionary.keys():
        node.setAttribute( fred, Description_Dictionary[ fred ] )

Is that the kind of thing you were looking for?
