I haven't tried this in particular, but I can tell you that the
ElementTree API for doing XML processing in Python is going to be
considerably simpler for something like this. ElementTree is available
at http://effbot.org/zone/element-index.htm, and will be in the standard
library starting with 2.5.
Here's a rough translation of your example (barely tested, ymmv, etc...):
from elementtree import ElementTree
def catalog(request):
xml_doc = ElementTree.parse('/usr/web/www/test.xml')
datum = ""
for node in xml_doc.getiterator():
datum = "%s<br />%s - %s" % (datum, node.tag, node.text)
return render_to_response('templates/generic_output.html',
{'output':datum})
Hope that helps.
