A Wiki of Objects

xmlWiki is a modification of the index.php page offering new features which are all maintained from editing normal wiki articles.

• All articles are objects stored in XML
• An additional xml page allows editing the data aspect of an article as a tree.
• A permissions structure offering basic read/write control over articles with users and groups.
• PHP Functions can be created and maintained by developers and can be dynamically applied to articles before rendering.
• Articles can made to automatically publish remotely over HTTP or FTP when edits are saved.

If the browser is fully XML-capable, then requested articles can be returned as XML for the client to transform with an XSLT and render. If not, xmlWiki can transform the document before returning it to the client.

The structure of xmlWiki

The xmlWiki layer is composed of a single PHP script called xmlwiki.php which, when called directly hooks or unhooks itself from three places in the MediaWiki index.php script.

The eneral structure of the xmlwiki.php script is as follows:
