wpxslgui is a Windows application which converts an XML File generated by the WordPress Export function into an HTML or Word HTML document.
Due to an undeclared element (namespace) in the file generated by WordPress, the application caused an exception and required manually editing the XML file to remove these elements. (see technical details here)
This bug has been fixed now, and the new version of wpxslgui can be download here.
Export your WordPress blog to XML, and convert into any of the supported output formats.
