    Feed Cache trouble

    Hi guys,

    I needed to display an RSS feed from an external source and I found Darren Fergusons Feed Cache which seemed to be able to do the trick.

    The trouble is that Fergusons XSLT is displaying XML that looks like this:

    <feed>
        <entry>...</entry>
        <entry>...</entry>
    </feed>

    and the source of the feed I need to display looks like this:

    <rss>
        <channel>
            <item>...</item>
            <item>...</item>
        </channel>
    </rss>

    My question is: How do I customize Fergusons XSLT to display the feed above:

    <?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"
     exclude-result-prefixes="msxml umbraco.library Atom"
     xmlns:Atom="http://www.w3.org/2005/Atom">
       
        <xsl:variable name="y" select="document('../umbraco/plugins/FergusonMoriyama/FeedCache/twit.xml')/Atom:feed"/>
        <xsl:output method="xml" omit-xml-declaration="yes"/>
        <xsl:param name="currentPage"/>
       
        <xsl:template match="/">
            <xsl:for-each select="$y/Atom:entry">
                <p>
                    <em>
                        <xsl:value-of select="umbraco.library:FormatDateTime(Atom:published, 'MMMM d, yyyy @ H:mm')"/>
                    </em>
            <xsl:value-of select="Atom:content" disable-output-escaping="yes"/>
                </p>
            </xsl:for-each>
        </xsl:template>
    </xsl:stylesheet>

    The package has been installed correctly (its no problem to display Fergusons Twit feed). Hope someone can help!

    I have not used this package before... But you could have a look in twit.xml to see if there is a feed definition in there. If so, you can probably change "entry" into "item" and you should be good to go. If not.. then I don't know ;-)

    Thanks Sebastiaan! I've already tried replacing "entry" with "item", "feed" with "rss" and included "channel" in different way - and nothing seems to work! No output... Thanks for your suggestion though! :)

    No problem! Oh by the way, you might also need to change the "Atom:" references to convert to rss feeds instead of atom feeds. I am not familiar with the "Atom:" notation in this XSLT though.

    The feed I want to use is also an ATOM-feed - so no problem there ;)

    Hi Jonas, what is the URL of the feed you want to transform?

    To me it looks like you're getting your feed types mixed up. You say that it's storing in the "<feed><entry></entry></feed>" format. That looks like an ATOM feed to me.

    I found a random ATOM feed and put together this XSLT file. Works fine for me:

    <?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:atom="http://www.w3.org/2005/Atom"
    exclude-result-prefixes="msxml umbraco.library atom">

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

  <xsl:param name="currentPage"/>
  <xsl:param name="numberOfItems">
    <!--<xsl:value-of select="/macro/numberOfItems"/>-->
    <xsl:text>5</xsl:text>
  </xsl:param>

  <xsl:param name="dataPath">
    <xsl:value-of select="umbraco.library:RequestServerVariables('APPL_PHYSICAL_PATH')"/>
    <xsl:text>umbraco\plugins\FergusonMoriyama\feedcache\sophos-security-news.xml</xsl:text>
    <!--<xsl:value-of select="/macro/cachedFeedFile"/>-->
  </xsl:param>

  <xsl:param name="feedData" select="umbraco.library:GetXmlDocument($dataPath,false)"/>

  <xsl:template match="/">
    <div class="display-feed">
      <xsl:apply-templates select="$feedData//atom:entry [position() &lt;= $numberOfItems]"/>
    </div>
  </xsl:template>

  <xsl:template match="atom:entry">
    <dl>
      <a class="feed-link">
        <xsl:attribute name="href">
          <xsl:value-of select="atom:link"/>
        </xsl:attribute>
        <xsl:value-of select="atom:title"/>
      </a>
    </dl>
    <dt>
      <xsl:value-of select="umbraco.library:StripHtml(atom:summary)"/>
    </dt>
  </xsl:template>

</xsl:stylesheet>

    Forgot to mention, feedcache doesn't change the format of the feed. You can even cache ICS iCal files.

    The XSLT file for an RSS-formatted feed would be as follows:

    <?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:atom="http://www.w3.org/2005/Atom"
    exclude-result-prefixes="msxml umbraco.library atom">

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

  <xsl:param name="currentPage"/>
  <xsl:param name="numberOfItems">
    <!--<xsl:value-of select="/macro/numberOfItems"/>-->
    <xsl:text>5</xsl:text>
  </xsl:param>

  <xsl:param name="dataPath">
    <xsl:value-of select="umbraco.library:RequestServerVariables('APPL_PHYSICAL_PATH')"/>
    <xsl:text>umbraco\plugins\FergusonMoriyama\feedcache\sophos-security-rss-news.xml</xsl:text>
    <!--<xsl:value-of select="/macro/cachedFeedFile"/>-->
  </xsl:param>

  <xsl:param name="feedData" select="umbraco.library:GetXmlDocument($dataPath,false)"/>

  <xsl:template match="/">
    <div class="rss-feed">
      <xsl:apply-templates select="$feedData//item [position() &lt;= $numberOfItems]"/>
    </div>
  </xsl:template>

  <xsl:template match="item">
    <dl>
      <a class="feed-link">
        <xsl:attribute name="href">
          <xsl:value-of select="./link"/>
        </xsl:attribute>
        <xsl:value-of select="./title"/>
      </a>
    </dl>
    <dt>
      <xsl:value-of select="umbraco.library:StripHtml(./description)"/>
    </dt>
  </xsl:template>

</xsl:stylesheet>

    Daniel S: The feed I need to display is not <feed><entry></entry></feed> but <rss><channel><item></item></channel></rss>. I will try out your examples.

    Darren: It's located at http://helpanoutdoor.dk/rss/catalog/new/sid/1/
