Hi all. 

I'm searching for a way to cache a lot of xml content. The xml is fetched from different external sources and transformed using xslt. 

The xml will be used in almost all xslt macros in the solution.

Example:

<xsl:template name="treebuilder">
  <xsl:param name="currentPage"/>

   <xsl:variable name="id" select="$currentPage/ancestor-or-self::MainMaster/ID"/>
   <xsl:variable name="fixid" select="$currentPage/ancestor-or-self::MainMaster/FixId"/>
   <xsl:variable name="xmlcat" select="external.Api:GetMyData(id, '')"/>


  <xsl:variable name="treetosave">
      <katalog id="{$xmlcat//id}" navn="{$xmlcat//vNavn}">
        <beskrivelse>
          <xsl:value-of select="umbraco.library:ReplaceLineBreaks($xmlcat//vBeskrivelse)" disable-output-escaping="yes"/>
        </beskrivelse>
        <kategorier>
          <xsl:attribute name="antal">
            <xsl:value-of select="count($xmlcat//Table [string(uid) = ''])"/>
          </xsl:attribute>

          <xsl:call-template name="buildkat">
            <xsl:with-param name="src" select="$xmlcat//Table [string(uid) = ''] "/>
            <xsl:with-param name="allsrc" select="$xmlcat"/>
            <xsl:with-param name="level" select="1"/>
            <xsl:with-param name="currentPage" select="$currentPage"/>

          </xsl:call-template>
        </kategorier>
      </katalog>
</xsl:variable>
</xsl:template>
