Deal lxml Developers, I want to use your library for some projects that I will need XML parsing and XSD verification. I am attempting to install lxml 3.2.1 onto a RHEL 6.1 server which has python 2.6.6 installed. I did not use pip to build and install lxml, rather I used the 'python setup.py install'. Everything seemed to build and install fine. I was able to run through a few tutorials with out any issue. My problem came when I decided to try and run the unit tests that you have provided. I get one failure (see bottom of this E-Mail) when I run the 'make test' or 'python test.py -p -v' command. I have tried this on lxml versions of 3.1.2, 3.2.0, and 3.2.1 and I see the same test error on each release. I have attempted to sower the web, and the lxml mailing list archives to see if I could find any information on what is causing this test to fail, but I have come up empty. I am hoping that one of you can tell me what I am doing wrong, or what I can to to get this test to pass.

My educated guess is that it's an issue with libxml2. The 2.7.x versions below 2.7.8 are known to have varying minor issues. If you can't (easily) upgrade your system library, consider a static lxml build, preferably using the latest libxml2 2.9.x release. Alternatively, test your own code with what you have and if that works, it's unlikely to magically start failing without modifications. Bugs in libxml2 often just impact specific features (such as push parsing above), not all of lxml. Stefan
