= FastXSL =

FastXSL is an extension to PHP to make applying XSLT transforms to XML faster.

== How it works ==

In Apache/PHP the process of applying an XSLT transform to an XML document requires a few steps.  First the XSLT document must be parser, then compiled and then applied to a parser XML document.  Under typical usage, the XML document is different every time, but the XSLT stylesheet document changes rarely.  Due to the Apache/PHP process model (separate processes serve different request), a compiled XSLT stylesheet cannot be shared between the processes.

The {{{fastxsl}}} extension attempts to tackle this issue by leveraging libmm and subverting the libxml2 memory system to cache compiled XSLT documents and make them accessible to any Apache/PHP process in need.  In addition, the extension allow for the caching of XML documents which can be useful if any large static XML documents are used by the application.
