Hi all: I'm working in a parser for XML files and i found and behaviour in lxml-python both in linux and os x. When i try to use .find() or findall() functions, the problem seams to be when someone try to deal with tag declared inside a namespace without prefix. Here an example to reproduce the bug: Vengeance:ioc luisgf$ python3 Python 3.4.2 (v3.4.2:ab2c023a9432, Oct 5 2014, 20:42:22) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information. line 281, in find it = iterfind(elem, path, namespaces) File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/lxml/_elementpath.py", line 271, in iterfind selector = _build_path_iterator(path, namespaces) File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/lxml/_elementpath.py", line 234, in _build_path_iterator return _cache[(path, namespaces and tuple(sorted(namespaces.items())) or None)] TypeError: unorderable types: NoneType() < str()

Thanks for the report. That's a bug. "None" prefixes should be rejected with a visible ValueError. There is no reason why they should be accepted. (Note that your example above is contrived. You'd never pass an unknown prefix-namespace map in real code.) Stefan
