How to export text from all pages of a MediaWiki?

Question

I have a MediaWiki running which represents a dictionary of German terms and their translation to a local dialect. Each page holds one term, its translation and a number of additional infos.

Now, for a printable version of the dictionary, I need a full export of all terms and their translation. Since this is an extract of a page's content, I guess I need a complete export of all pages in their newest version in a parsable format, e.g. xml or csv.

Has anyone done that or can point me to a tool? I should mention, that I don't have full access to the server, e.g. no command line, but I am able to add MediaWiki extensions or access the MySQL database.

You can export the page content directly from the database. It will be the raw wiki markup, as when using Special:Export. But it will be easier to script the export, and you don't need to make sure all your pages are in some special category.

Here is an example:

SELECT page_title, page_touched, old_text
FROM revision,page,text
WHERE revision.rev_id=page.page_latest
AND text.old_id=revision.rev_text_id;

If your wiki uses Postgresql, the table "text" is named "pagecontent", and you may need to specify the schema. In that case, the same query would be:

SET search_path TO mediawiki,public;

SELECT page_title, page_touched, old_text 
FROM revision,page,pagecontent
WHERE revision.rev_id=page.page_latest
AND pagecontent.old_id=revision.rev_text_id;

This worked very well for me. Notice I redirected the output to the file backup.xml. From a Windows Command Processor (CMD.exe) prompt:

cd \PATH_TO_YOUR_WIKI_INSTALLATION\maintenance
\PATH_OF_PHP.EXE\php dumpBackup.php --full > backup.xml
