Subject: added support to parse namespaces from title
X-Git-Url: https://code.communitydata.science/mediawiki_dump_tools.git/commitdiff_plain/d934700ee9f8b9bb5e9d8a1fbea684dc2f54eba7?ds=inline;hp=108c8442b211065606f81f3facbde23d3377ec6c

added support to parse namespaces from title

This is necessary for wikis (e.g., Wikia XML dumps) that do not include
namespace metadata as tags within each <page>.
