# MediaWikiDump >[MediaWiki XML Dumps](https://www.mediawiki.org/wiki/Manual:Importing_XML_dumps) contain the content of a wiki > (wiki pages with all their revisions), without the site-related data. A XML dump does not create a full backup > of the wiki database, the dump does not contain user accounts, images, edit logs, etc. ## Installation and Setup We need to install several python packages. The `mediawiki-utilities` supports XML schema 0.11 in unmerged branches. ```bash pip install -qU git+https://github.com/mediawiki-utilities/python-mwtypes@updates_schema_0.11 ``` The `mediawiki-utilities mwxml` has a bug, fix PR pending. ```bash pip install -qU git+https://github.com/gdedrouas/python-mwxml@xml_format_0.11 pip install -qU mwparserfromhell ``` ## Document Loader See a [usage example](../modules/indexes/document_loaders/examples/mediawikidump.ipynb). ```python from langchain.document_loaders import MWDumpLoader ```
