Hi all; I think that there is an error in xmlreader.py. When parsing a full revision XML (in this case[1]), using this code[2] (look at the try-catch, it writes when fails) I get correctly username, timestamp and revisionid, but sometimes, the page title and the page id are None or empty string. The first error is: ['', None, 'QuartierLatin1968', '2004-10-10T04:24:14Z', '4267'] But if we do: 7za e -bd -so kwwiki-20100926-pages-meta-history.xml.7z 2>/dev/null | egrep -i '2004-10-10T04::14Z' -C20 We get this[3], which is OK, the page title and the page id are available in the XML, but not correctly parsed. And this is not the only page title and page it that fails. Perhaps I have missed something, because I'm learning to parsing XML. Sorry in that case.
