I am trying to process ATOM search results from twitter using the umbraco.library:GetXmlDocumentByUrl.

I have very much copied the approach from the Twitter4Umbraco project where I know this works, however when applying this to the ATOM search xml, I am having difficulty using xpath to drill down into the document.

Here is what I have:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
 version="1.0" 
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
 xmlns:msxml="urn:schemas-microsoft-com:xslt"
 xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
 exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template match="/">

  <xsl:variable name="MyFeed" select="umbraco.library:GetXmlDocumentByUrl('http://search.twitter.com/search.atom?q=umbraco')" />

  <!-- this works - shows me the contents of the variable -->
  <textarea>
    <xsl:copy-of select="$MyFeed" />
  </textarea>

  <br />
  
  <!-- this doesn't :( -->
  <textarea>
    <xsl:copy-of select="$MyFeed//feed/entry" />
  </textarea>
  
  <!-- Once its working, I want to-do something like this -->
  <xsl:for-each select="$MyFeed//feed/entry">
    <xsl:apply-templates mode="result" select="current()"/>
  </xsl:for-each>

</xsl:template>

<xsl:template match="entry" mode="result">

  <!-- Once I'm here, I can do my stuff! but for now .. -->
  <div>
    <p>
      <xsl:value-of select="title" />
    </p>
  </div>
 
</xsl:template>

</xsl:stylesheet>

Im pretty sure its got somehting todo witht the namespaces being used in the document held in the variable, however i'm losing the plot a little trying to get this to work!

Any help much appreciated.

Thanks,

Adam
