[xsl] Merging multiple RSS feeds into one RSS feed

[Robert Fidler <robert.fidler@xxxxxxxxxx>]

Does any one know how I can merge multiple RSS feeds into one feed? I 
have this code, but when I view the feed.xml in IE, it does not have any 
of the XML formating in it, just plain text output all strong out. And 
RSSOwl does not even read it.

feed.xml:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="merge-rss.xsl"?>
<feeds>
   <link href="http://digg.com/rss/index.xml"/>
   <link href="http://www.osnews.com/files/recent.xml"/>
</feeds>

merge-rss.xsl:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
   <xsl:output  method="xml" version="1.0" encoding="UTF-8" 
indent="yes" omit-xml-declaration="no" media-type="text/xml" />
   <xsl:template match="/">
       <rss version="2.0">
           <channel>
               <title>My Title</title>
               <description>My Description</description>
               <language>en-us</language>
               <link>http://mysite/rss</link>
               <xsl:for-each select="feeds/link/@href">
                   <xsl:copy-of select="document(.)/rss/channel/item"/>
               </xsl:for-each>
           </channel>
       </rss>
   </xsl:template>
</xsl:stylesheet>
