Tvorba rozšíření CMS Joomla podporující automatické XSLT

The work is focused on extending the Joomla content plugin - XSLT Magic - written by Bc. Michal Vrchnota. This plugin was developed as a part of the SEWEBER CMS project. The main purposes of this plugin are XSLT transformations of articles made up from XML documents. One of the main reasons for creation of this work was the increasing number of transformations and their unsolved management. Another reason was bad controllability of this component and the lack of admin interface. The extension made up as a part of this work allows users to effectively manage XSLT transformations. Users will be able to look into the directory, where the transformations are being stored directly throught the CMS Joomla system. This wasn't possible up to now, because the the CMS system in its basic version lacks the component to manage files. Additionaly, users will be able to upload files into these directories and create new sub-directories. Looking into the transformations will not be a problem anymore, users will even be able to edit them in a simple text editor with marked XML syntax. Second part of the extension is focused on the administration of the original content plugin. The configuration has been made easier, so selecting transfomation to the XPath rule is simplier and users now can select the transformation from a list. This work can be used as an inspiration in creating new extensions for CMS Joomla.
