I have a very simple XML document that I need to "walk", and I'm using
xml.dom.minidom. No attributes, just lots of nested tags and associated
values. All I'm looking to do is iterate through each of the highest
sibling nodes, check what the tag is, and process its value accordingly.
If
a node has children, same thing - iterate through the nodes, check the
tags
and process the values accordingly. I see where each node object has a
"childNodes" attribute, so I can drill down the tree. But what are the
node
attributes which indicate Tag and Value? I thought it would have been
nodeName and nodeValue, but that doesn't seem to be. Does anyone know?
Thanks in advance, TommyVee
Ah maybe you're confused about how text nodes work in minidom. Every element
will have a nodeName attribute (not callable) but if you try el.nodeValue on
a text node you get None. That's because the text is represented by a child
node with nodeName '#text', so you want (el.nodeName,
el.firstChild.nodeValue).
General tips - try the docs:
http://docs.python.org/library/xml.dom.minidom.html
and also use dir() a lot on objects when you're learning a new api.
Hope that helps. Disclaimer: haven't used minidom in anger for some time.
Confused? That's an understatement. Part of the problem is that it's been
a long time since I learned DOM and now I'm trying to cram to get this
program done.
Anyway, your suggestion to access el.firstChild.nodeValue did the trick.
Thanks
