elementsoap with Python 2.5

[Steven Bethard]

I was trying to get elementsoap_ working with just xml.etree from Python
2.5 (and no standalone elementtree installation). I think I got
everything working by changing the imports and copying in the
FancyTreeBuilde r class (since only TreeBuilder and XMLTreeBuilder are in
the xml.etree.Eleme ntTree module). I've attached the diff. Does this
seem like the right approach? I'd rather not have to install
elementtree alongside the one in the stdlib...

the really correct approach would be to rewrite the code to use the
"iterparse" API instead.

FancyTreeBuilde r relies on various internals, but your copy-and-paste
fix should work just fine for Python 2.5 and/or ElementTree 1.2.
