Hi there, I had spotted a NameError in docloader.pxi, but fixed it locally then forgot to send the patch. So here it is. It did bite me on the back when I tried to compile lxml-trunk on another box :) Traceback: File "xslt.pxi", line 593, in etree._XSLTProcessingInstruction.parseXSL File "parser.pxi", line 889, in etree._parseDocument File "parser.pxi", line 893, in etree._parseDocumentFromURL File "parser.pxi", line 810, in etree._parseDocFromFile File "parser.pxi", line 522, in etree._BaseParser._parseDocFromFile File "parser.pxi", line 591, in etree._handleParseResult File "etree.pyx", line 201, in etree._ExceptionContext._raise_if_stored File "parser.pxi", line 285, in etree._parser_resolve_from_python File "docloader.pxi", line 84, in etree._ResolverRegistry.resolve File "lxmlfilter.pyc", line 50, in resolve File "docloader.pxi", line 47, in etree.Resolver.resolve_file NameError: _ParserInput -- Sidnei da Silva http://www.enfoldsystems.com
