[OpenSIPS-Users] upgrade to openxcap 1.0.2 failed

You can also try to install pyxml manually, with "sudo python setup.py 
install".

pyxml library provides _xmlplus package, which contains the same classes as
xml package in Python's standard library, but with a bit different 
implementation.
In particular, expat parser in _xmlplus implements the desirable 
feature, while
the standard one does not.

When _xmlplus is present and of adequate version, xml package uses it 
instead of self:
http://svn.python.org/view/python/tags/r252/Lib/xml/__init__.py?rev=60915&view=auto

So you have to ensure that "import _xmlplus" works with your Python.

The older versions of OpenXCAP also required _xmlplus. However, they 
didn't check at
startup that it was present, so they would fail on element operation 
with unclear error:
