Example

Consider the following example about a bookstore:

example.xslxml

<?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>  
			<p>  
			Version:  
			<xsl:value-of select="system-property('xsl:version')"  />  
			<br />  
			Vendor:  
			<xsl:value-of select="system-property('xsl:vendor')"  />  
			<br />  
			Vendor URL:  
			<xsl:value-of select="system-property('xsl:vendor-url')"  />  
			</p>  
		</body>  
	</html>  
</xsl:template>  
  
</xsl:stylesheet>

And the output is:

<html>  
	<body>  
		<p> Version: 1.0<br/>
		Vendor: libxslt<br/>
		Vendor URL: http://xmlsoft.org/XSLT/</p>  
	</body>  
</html>
