parsing nested unbounded XML fields with ElementTree

[Larry.Martell at gmail.com]

I have an XML file that has an element called "Node". These can be nested to any depth and the depth of the nesting is not known to me. I need to parse the file and preserve the nesting. For exmaple, if the XML file had:

<Node Name="A">
   <Node Name="B">
      <Node Name="C">
        <Node Name="D">
          <Node Name="E">

When I'm parsing Node "E" I need to know I'm in A/B/C/D/E. Problem is I don't know how deep this can be. This is the code I have so far:

nodes = []

def parseChild(c):
    if c.tag == 'Node':
        if 'Name' in c.attrib: 
            nodes.append(c.attrib['Name'])
        for c1 in c:
            parseChild(c1)
    else:
        for node in nodes:
            print node,
        print c.tag

for parent in tree.getiterator():
    for child in parent:
        for x in child:
            parseChild(x)

My problem is that I don't know when I'm done with a node and I should remove a level of nesting. I would think this is a fairly common situation, but I could not find any examples of parsing a file like this. Perhaps I'm going about it completely wrong.
