简介

The XSL extension implements the XSL standard, performing XSLT transformations using the libxslt library.

安装

PHP 5 includes the XSL extension by default and it can be enabled by adding the argument --with-xsl[=DIR] to your configure line. DIR is the libxslt installation directory. libxslt version 1.0.18 or greater is required.

例

In this small tutorial we will learn how to transform an XML document into HTML.

例子 1. A simple XSL tree <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html" encoding="iso-8859-1" indent="no"/> <xsl:template match="collection"> Hey! Welcome to my sweet CD collection! <xsl:apply-templates/> </xsl:template> <xsl:template match="cd"> <h1><xsl:value-of select="title"/></h1> <h2>by <xsl:value-of select="artist"/></h2> <h3> - <xsl:value-of select="year"/></h3> </xsl:template> </xsl:stylesheet>

例子 2. Corresponding XML tree <collection> <cd> <title>PHP Rock</title> <artist>Joe Coder</artist> <year>2003</year> </cd> <cd> <title>Squashing Typos on a Winter's Eve</title> <artist>kennyt</artist> <year>2004</year> </cd> </collection>

例子 3. Making XML into HTML The following PHP code uses the XML and XSL extensions to transform XML into presentable HTML. <?php /* Load the two XML sources */ $xml = new DomDocument; // from /ext/dom $xml->load('example.xml'); $xsl = new DomDocument; $xsl->load('example.xsl'); /* Configure the transformer */ $proc = new xsltprocessor; $proc->importStyleSheet($xsl); // attach the xsl rules echo $proc->transformToXML($xml); // actual transformation ?> This should produce an HTML fragment similar to the following: Hey! Welcome to my sweet CD collection! <h1>PHP Rock</h1> <h2>by Joe Coder</h2> <h3> - 2003</h3> <h1>Squashing Typos on a Winter's Eve</h1> <h2> by kennyt</h2> <h3> - 2004</h3>
