A XML dump does not create a full backup of the wiki database, the dump does not contain user accounts, images, edit logs, etc.This covers how to load a MediaWiki XML dump file into a document format that we can use downstream.It uses mwxml from mediawiki-utilities to dump and mwparserfromhell from earwig to parse MediaWiki wikicode.Dump files can be obtained with dumpBackup.php or on the Special:Statistics page of the Wiki.# mediawiki-utilities supports XML schema 0.11 in unmerged branchespip install -qU git+https://github.com/mediawiki-utilities/python-mwtypes@updates_schema_0.11# mediawiki-utilities mwxml has a bug, fix PR pendingpip install -qU git+https://github.com/gdedrouas/python-mwxml@xml_format_0.11pip install -qU mwparserfromhellfrom langchain.document_loaders import MWDumpLoaderloader = MWDumpLoader("example_data/testmw_pages_current.xml", encoding="utf8")documents = loader.load()print(f"You have {len(documents)} document(s) in your data ")    You have 177 document(s) in your data documents[:5]    [Document(page_content='\t\n\t\n\tArtist\n\tReleased\n\tRecorded\n\tLength\n\tLabel\n\tProducer', metadata={'source': 'Album'}),     Document(page_content='{| class="article-table plainlinks" style="width:100%;"\n|- style="font-size:18px;"\n! style="padding:0px;" | Template documentation\n|-\n| Note: portions of the template sample may not be visible without values provided.\n|-\n| View or edit this documentation.
