Hi everyone,
I thought I would mention a couple of MediaWiki extensions I have developed in case they might be useful to the community.
One extension is an interface for users to more easily export multiple wiki pages to XML, PDF and HTML by using the search function. The open source software HTML2FPDF is used for exports to PDF. MediaWiki's native XML exporter is used for the XML. The way the search is used is, the user first enters a search term, then the returned page names in which the search term appears are appended to the list of pages to be exported. They can dump those pages at any time to any of the formats (an installation with this extension can be seen at http://pgrdictionary.org/en/index.php/Special:DocumentExport (this install is a plant genetic resource dictionary, so use plant genetic terms, such as chromosome, to get search returns) ).
The other extension goes through every page in your Wiki, looking for Wiki page titles in the content of each page and Wiki-linking those words to their corresponding Wiki pages. It's meant to be used after you have imported fresh content into your Wiki, when that content does not yet contain any links between Wiki pages.
Hopefully they are useful, please let me know if they are.
thanks, Andrew.
