Using the previous code snippet which prepared an XML file it can now be transformed to RSS using the XSL below.


file: gang2rss.xsl

   1  
   2  <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
   3  
   4  	<xsl:output method="xml" encoding="iso-8859-1" indent="yes"  />
   5  
   6  	<xsl:template match="rss">
   7  
   8  		<rss version="2.0">	
   9  		<channel>
  10  		<title>The Gang</title>
  11  		<link>http://newsgang.net/audio/</link>
  12  		<description>The Gang podcast</description>
  13  
  14    	<language>en</language>
  15  
  16  	<xsl:apply-templates select="item" />
  17  
  18  		</channel>
  19  		</rss>
  20  
  21  	</xsl:template>
  22  
  23  	<xsl:template match="item">
  24  
  25  	<item>
  26  		<title><xsl:value-of select="title"/></title>
  27  		<link>http://newsgang.net<xsl:value-of select="href"/></link>
  28  		<description><xsl:value-of select="date"/></description>
  29  		<enclosure>http://newsgang.net<xsl:value-of select="href_audio"/></enclosure>
  30  	</item>
  31  
  32  	</xsl:template>	
  33  
  34  </xsl:stylesheet>

To transform the xsl file from the command-line you would type:

xsltproc gang2rss.xsl thegang_rss.xml

output

   2  <?xml version="1.0" encoding="iso-8859-1"?>
