Drop VersionConverter broken XML file support by mpsonntag · Pull Request #301 · G-Node/python-odml

The VersionConverter dealt with an edge case of XML test files with opening <B0> tags that were missing their closing tag rendering them broken. Catching this one edge case circumvented opening XML files via lxml, leaving the resulting document open to various encoding problems.

This PR drops support to resolve the specific tag edge case in favour of properly opening XML files via lxml.
