# CXIX. XSL functions

이 확장 모듈은 실험적입니다. 이 확장 모듈의 작동 -- 함수의 이름과 이 확장 모듈에 대한 모든 문서 자료에 대해서 -- 은 이후의 PHP 릴리즈에서 예고 없이 변경될 수 있습니다. 이 확장 모듈의 사용은 사용자의 책임하에 이루어집니다.

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

# 설치

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.

# 예제

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

예 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>

예 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>

예 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>
