Re: try-ark problem: reveal arkbase

Below is what I scribbled back to Harlan's problem with no
"normalize" method in his XML-grokking machinery.

I am a bit worried that we aren't achieving the "2.0 with no
PyXML" thing.  I *thought* that's what I was using at work,
but it's possible it is too-cleverly finding some PyXML bits
that I have on the system.

This looks like a mix-and-match-versions-of-Python-and-PyXML
thing.  We certainly haven't worked it all out (we don't
have all the combinations, after all.)

Combinations known to work include:

* Plain python 2.0/ no PyXML -- it has minidom included

* python 1.6 + PyXML 0.5.5.1

I'm *guessing* you're doing 1.6 + a newer PyXML that
includes minidom.

The code that's leading you astray is:

        try: # works for 2.0/... ?
#            import xml.dom.ext.reader.Sax
#            doc  = xml.dom.ext.reader.Sax.FromXmlStream(thing_file)
            import xml.dom.minidom
            doc  = xml.dom.minidom.parse(filename)
            root_elem = doc.documentElement
        except ImportError:
            #thing_file.close() # because we're about to reopen it
            import xml.dom.core
            import xml.dom.utils
            doc  = xml.dom.utils.FileReader().readFile(filename)
            root_elem = doc.documentElement

You're unsuspectingly succeeding on the "try" bit.
You could comment out "try...except" to make sure you get
"import xml.doc.core".

That's a *hack*; I'll need to think what the right thing to
do is.

PS: The goal for Python 2.x is "no PyXML needed, just Python".
