Religionwiki:export

Wiki pages can be exported in a special XML format to import into another MediaWiki installation or use it elsewise for instance for analysing the content. See also m:Syndication feeds for exporting other information but pages and Help:Import on importing pages.
== How to export ==
There are at least four ways to export pages:
* Paste the name of the articles in the box in Special:Export or use .
* The backup script dumpBackup.php dumps all the wiki pages into an XML file. dumpBackup.php only works on MediaWiki 1.5 or newer. You need to have direct access to the server to run this script. Dumps of mediawiki projects are (more or less) regularly made available at http://download.wikipedia.org. 
* There is a OAI-PMH-interface to regularly fetch pages that have been modified since a specific time. For Wikimedia projects this interface is not publicly available. OAI-PMH contains a wrapper format around the actual exported articles.
* Use the Python Wikipedia Robot Framework. This won't be explained here.
By default only the current version of a page is included. Optionally you can get all versions with date, time, user name and edit summary.
Additionally you can copy the SQL database. This is how dumps of the database were made available before MediaWiki 1.5 and it won't be explained here further.
===Using 'Special:Export'===
To export all pages of a namespace, for example.
====1. Get the names of pages to export====
* Go to Special:Allpages and choose the desired namespace. 
* Copy the list of page names to a text editor
* Put all page names on separate lines
* Prefix the namespace to the page names (e.g. 'Help:Contents'), unless the selected namespace is the main namespace.
====2. Perform the export====
* Go to Special:Export and paste all your page names into the textbox, making sure there are no empty lines.
* Click 'Submit query'
* Save the resulting XML to a file using your browser's save facility.
and finally...
* Open the XML file in a text editor. Scroll to the bottom to check for error messages.
Now you can use this XML file to perform an import.
====Exporting the full history====
A checkbox in the Special:Export interface selects whether to export the full history (all versions of an article) or the most recent version of articles. A maximum of 100 revisions are returned; other revisions can be requested as detailed in MW:Parameters to Special:Export.
== Export format ==
The format of the XML file you receive is the same in all ways. It is codified in XML Schema at http://www.mediawiki.org/xml/export-0.3.xsd This format is not intended for viewing in a web browser. Some browsers show you pretty-printed XML with "+" and "-" links to view or hide selected parts. Alternatively the XML-source can be viewed using the "view source" feature of the browser, or after saving the XML file locally, with a program of choice. If you directly read the XML source it won't be difficult to find the actual wikitext. If you don't use a special XML editor "<" and ">" appear as &lt; and &gt;, to avoid a conflict with XML tags; to avoid ambiguity, "&" is coded as "&amp;".
In the current version the export format does not contain an XML replacement of wiki markup . You only get the wikitext as you get when editing the article. (After export you can use alternative parsers to convert wikitext to other format)
