I am very new to XML & XSL but I know there is a way to build blog aggregators. I have a XML document that pulls the blogs in with the URI:

<?xml version="1.0"?>

<!DOCTYPE feeds SYSTEM "feeds.dtd">
<feeds>
    
     <feed name="Mary Rose's Blog"
        provider="Blogabond"
        spec="rss"
        version="2.0"
        uri="http://www.blogabond.com/rss/rss.aspx?UserID=7835">
         <keyword name="meow"/>
      
    </feed>
</feeds>

I also have a .xsl document that prints all the blog entries out properly:

<?xml version="1.0"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:atom="http://www.w3.org/2005/Atom"
  xmlns:openSearch="http://a9.com/-/spec/opensearchrss/1.0/"
  xmlns:georss="http://www.georss.org/georss"
  xmlns:aml="http://markup-languages.googlecode.com/ns/aml"
  version="1.0">
  

  <xsl:output method="xml" indent="yes" />
  
  <xsl:template match="/feeds" >
    <aml:aggregated>
      <xsl:for-each select="feed">
        <xsl:element name="aml:blog">
          <xsl:copy-of select="@uri"/>  
          <xsl:apply-templates select="document(@uri)" mode="document"/>
          <xsl:apply-templates select="keyword" mode="document" />
        </xsl:element>
      </xsl:for-each>
    </aml:aggregated>
  </xsl:template>
  
  <xsl:template match="rss/channel" mode="document">
    <xsl:for-each select="item">
      <xsl:sort order="descending" select="atom:updated/text()"/>
      <xsl:copy-of select="."/>
 
    </xsl:for-each>
  </xsl:template>
  
</xsl:stylesheet>

Now the problem I am having is sorting by the keyword I indicated in the XML document. As you can see I tried using the apply-templates but it still pulls in all the blog entries.

Another thing I want to do is more feeds to my XML file but different feeds do not use <pubDate> so how do I convert it to actualy print the <pubDate>. Any help would be most appreciated.
