XSLT transforment

Le diagramme repr�sente le processus de transformation : rentrant un document de XML, s'appliquant le dossier de XSLT aux noeuds du document de XML, et produire d'un autre document du format d�sir�.

Il se composent de deux fonctions. La premi�re fonction lit simplement un document de XML et transforme alors les donn�es en utilisant un dossier de XSLT. La deuxi�me fonction lit un document de XML, transforme les donn�es, et puis �crit un nouveau document de XML des donn�es transform�es.

Exemple 1 : - XML de transformation � XML

Transformation du document de XML

<?xml version="1.0"?>
<persons>
<person username="MP123456">
    <name>John</name>
    <family_name>Smith</family_name>
</person>
<person username="PK123456">
    <name>Morka</name>
    <family_name>Ismincius</family_name>
</person>
</persons>

Par l'application les XSLT transforment :

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<transform>
<xsl:apply-templates/>
</transform>
</xsl:template>
<xsl:template match="person">
<record>
<username>
<xsl:value-of select="@username" />
</username>
<name>
<xsl:value-of select="name" />
</name>
</record>
</xsl:template>
</xsl:stylesheet>

R�sultats dans un nouveau document de XML, ayant une autre structure :

<?xml version="1.0" encoding="UTF-8"?>
<transform>
   <record>
      <username>MP123456</username>
      <name>John</name>
   </record>
   <record>
      <username>PK123456</username>
      <name>Morka</name>
   </record>
</transform>

Exemple 2 : XML de transformation � XHTML

Exemple du document entrant de XML :

<?xml version="1.0" encoding="UTF-8"?>

<domains>
<sun.com ownedBy="Sun Microsystems Inc.">
<host>
www
<use>World Wide Web site</use>
</host>
<host>
java
<use>Java info</use>
</host>
</sun.com>

<w3.org ownedBy="The World Wide Web Consortium">
<host>
www
<use>World Wide Web site</use>
</host>
<host>
validator
<use>web developers who want to get it right</use>
</host>
</w3.org>
</domains>

Exemple XSLT Stylesheet :

<?xml version="1.0" encoding="UTF-8" ?>

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

doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"/>


<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>test1</title>
<style type="text/css">
h1 { padding: 10px; padding-width: 100%; background-color: silver }
td, th { width: 40%; border: 1px solid silver; padding: 10px }
td:first-child, th:first-child { width: 20% }
table { width: 650px }
</style>
</head>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>


<xsl:template match="domains/*">
<h1><xsl:value-of select="@ownedBy"/></h1>
<p>The following host names are currently in use at
<strong><xsl:value-of select="local-name(.)"/></strong>
</p>
<table>
<tr><th>Host name</th><th>URL</th><th>Used by</th></tr>
<xsl:apply-templates/>
</table>
</xsl:template>


<xsl:template match="host">

<xsl:variable name="url" select=
"normalize-space(concat('http://', normalize-space(node()), '.', local-name(..)))"/>
<tr>
<td><xsl:value-of select="node()"/></td>
<td><a href="{$url}"><xsl:value-of select="$url"/></a></td>
<xsl:apply-templates select="use"/>
</tr>
</xsl:template>


<xsl:template match="use">
<td><xsl:value-of select="."/></td>
</xsl:template>

</xsl:stylesheet>
