需求

This extension uses libxslt which can be found at » http://xmlsoft.org/XSLT/. libxslt version 1.1.0 or greater is required.

安装

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

范例

Many examples in this reference require both an XML and an XSL file. We will use collection.xml and collection.xsl that contains the following:

Example#1 collection.xml



<collection>


 <cd>


  <title>Fight for your mind</title>


  <artist>Ben Harper</artist>


  <year>1995</year>


 </cd>


 <cd>


  <title>Electric Ladyland</title>


  <artist>Jimi Hendrix</artist>


  <year>1997</year>


 </cd>


</collection>


Example#2 collection.xsl



<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">


 <xsl:param name="owner" select="'Nicolas Eliaszewicz'"/>


 <xsl:output method="html" encoding="iso-8859-1" indent="no"/>


 <xsl:template match="collection">


  Hey! Welcome to <xsl:value-of select="$owner"/>'s 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"/> - <xsl:value-of select="year"/></h2>


  <hr />


 </xsl:template>


</xsl:stylesheet>
