Hi,

first thing: don't use expat directly. Use (c)ElementTree's iterparse. It's
in
Python 2.5, but is also available as an external package for older Python
versions. There's also lxml (which is mostly compatible to ElementTree), in
case you ever need features like XPath, XSLT or whatever.

Better:

    ordtags = set(['offfnbr', 'afidlog', ...])

    from xml.etree.cElementTree import iterparse

    for onefile in allfiles:
        for event, element in iterparse(onefile):
            if element.tag in ordtags:
                 # do something like
                 values[element.tag] = element.text
            elif element.tag in shptags:
                 # do something else
            else:
                 # don't do anything?
            element.clear()
