XSLT <xsl:template>
XSLT <xsl:template>
The <xsl:template>
element contains rules to apply when a specified node is matched.
The match attribute is used to associate the template with an XML element. The match attribute can also be used to define a template for a whole branch of the XML document (i.e. match="/"
defines the whole document).
note
<xsl:template>
is a top-level element.
Syntax
<xsl:template
name="name"
match="pattern"
mode="mode"
priority="number">
<!-- Content:(<xsl:param>*,template) -->
</xsl:template>

Example
Consider the XML document about a bookstore shown below:
books.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="books.xsl"?>
<bookstore>
<book category="children">
<title lang="en">Harry Potter</title>
<author>J K. Rowling</author>
<year>2005</year>
<price>29.99</price>
</book>
<book category="web">
<title lang="en">XQuery Tips</title>
<author>Tom Nolan</author>
<year>2022</year>
<price>39.99</price>
</book>
<book category="web">
<title lang="en">Learn XML</title>
<author>Tutorial Reference</author>
<year>2022</year>
<price>9.99</price>
</book>
</bookstore>
We want to list title and author of each book:
books.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>The Bookstore</h2>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="book">
<p>
<xsl:apply-templates select="title"/>
<xsl:apply-templates select="author"/>
</p>
</xsl:template>
<xsl:template match="title">
Title: <span style="color:#ff0000">
<xsl:value-of select="."/></span>
<br />
</xsl:template>
<xsl:template match="author">
Author: <span style="color:#00ff00">
<xsl:value-of select="."/></span>
<br />
</xsl:template>
</xsl:stylesheet>
