Example 1. A Stylesheet <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
...
</xsl:stylesheet>
Example 2. A Transformation Sheet <eg:transform xmlns:eg="http://www.w3.org/1999/XSL/Transform"
version="1.0">
...
</eg:transform>
Example 3. Document as Stylesheet <html xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <head> <title>Silly Example</title> </head> <body> <h1>Silly Example</h1> <p>You'd probably use extension elements, or somthing more interesting in real life: 3+4 is <xsl:value-of select="3+4"/>. </p> </body> </html> A Complete Example This is a simple stylesheet that transforms source <para> and <emphasis> elements into HTML:
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:template match="para">
<p><xsl:apply-templates/></p>
</xsl:template>
<xsl:template match="emphasis">
<i><xsl:apply-templates/></i>
</xsl:template>
</xsl:stylesheet>
With this stylesheet, the following XML document: <?xml version='1.0'?> <para>This is a <emphasis>test</emphasis>.</para> Would be transformed into: <?xml version="1.0" encoding="utf-8"?> <p>This is a <i>test</i>.</p> Note that this has been serialized as XML. Understanding A Template Most templates have the following form: <xsl:template match="emphasis"> <i><xsl:apply-templates/></i> </xsl:template>
Match Patterns (Locating Elements) One critical capability of a stylesheet language is to locate source elements to be styled. CSS, for example, does this with "selectors." FOSIs do it with "e-i-c's", elements in context. XSLT does it with "match patterns" defined by the XML Path Language (XPath) (http://www.w3.org/TR/xpath).
Two things to remember about XPath expressions:
