CLXXV. XSL functions

Introdução

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

Dependências

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

Instalação

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.

Classes pré-definidas

XSLTProcessor

Construtor

XSLTProcessor->__construct() - construct a new XSLTProcessor object

Métodos

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

Exemplos

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:

Exemplo 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>

Exemplo 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>
