The version of ElementTree that ships with Python 2.6 only has
support for "path/path" style XPath syntax, and cannot handle paths
of the form "path/path[attr='val']/path", and will crash with a traceback similar to:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementTree.py", line 355, in findall
return ElementPath.findall(self, path)
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementPath.py", line 198, in findall
return _compile(path).findall(element)
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementPath.py", line 176, in _compile
p = Path(path)
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/xml/etree/ElementPath.py", line 93, in __init__
"expected path separator (%s)" % (op or tag)
SyntaxError: expected path separator ([)
For example, RHEL6 ships with Python 2.6, and lxml 2.2.3.

This patch uses
lxml.etreein place ofxml.etree.ElementTreeto retain Python 2.6 compatibility.
