Using SimpleXMLTreeBuilder in elementtree

django, elementtree, python

Solution

If you have third party module that wants to use ElementTree (and XMLTreeBuilder by dependency) you can change ElementTree's XMLTreeBuilder definition to the one provided by SimpleXMLTreeBuilder like so:

from xml.etree import ElementTree # part of python distribution
from elementtree import SimpleXMLTreeBuilder # part of your codebase
ElementTree.XMLTreeBuilder = SimpleXMLTreeBuilder.TreeBuilder

Now ElementTree will always use the SimpleXMLTreeBuilder whenever it's called.

Problem

I have been developing an application with django and elementtree and while deploying it to the production server i have found out it is running python 2.4. I have been able to bundle elementtree but now i am getting the error: ``` "No module named expat; use SimpleXMLTreeBuilder instead" ``` Unfortunately i cannot upgrade python so im stuck with what i got. How do i use SimpleXMLTreeBuilder as the parser and/or will i need to rewrite code?
