CLXXXIII. XSL functions

简介

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

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.

预定义类

`XSLTProcessor`

构造函数

XSLTProcessor::__construct - construct a new XSLTProcessor object

方法

XSLTProcessor::getParameter - Get value of a parameter
XSLTProcessor::hasExsltSupport - Determine if PHP has EXSLT support
XSLTProcessor::importStylesheet - Import stylesheet
XSLTProcessor::registerPHPFunctions - Enables the ability to use PHP functions as XSLT functions
XSLTProcessor::removeParameter - Remove parameter
XSLTProcessor::setParameter - Set value for a parameter
XSLTProcessor::transformToDoc - Transform to DOMDocument
XSLTProcessor::transformToURI - Transform to URI
XSLTProcessor::transformToXML - Transform to XML

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:

例2427.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>

例2428.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>
