This is a simple test of the xsl module which is compiled with PHP5 but was not included with PHP4 (and therefore it does not work with PHP4). It uses libxslt to perform XSLT
transformations. Essentially this allows for the data of an xml file to be transformed to a more readable format according to a template specified in an xsl (an xml styling standard)
file. This particular test uses a simple xsl template (plistConvert.xsl) to make 'iTunes Music Library.xml' file more easy to read.
