Re: Custom Logic Sheets: Request Parameters in Nested tags

Remove the apostrophes:

<xsl:variable name="id">
  <request:get-parameter name="template-id"/>
</xsl:variable>

Hi,

I am trying to develop a tag that would 
  - Get a parameter called "template-id" from the request
  - Fetch the template with that template-id from an XML config file

Here's is how I am trying to accomplish it:

<!-- ===================================================================== -->
<!-- Fetch the template matching tempalte-id in Request -->
<xsl:template match="gvs:fetch-template">
  <!-- Get template-id -->
  <xsl:variable name="id">'<request:get-parameter name="template-id"/>'</xsl:variable>
  <xsl:variable name="query-template">
   <xsl:call-template name="get-template">
     <xsl:with-param name="id" select="$id"/>
   </xsl:call-template>   
  </xsl:variable>
  <xsl:value-of select="$query-template"/>      
</xsl:template>
<!-- Get Query Template from queries.xml, given its ID -->
<xsl:template name="get-template">
  <xsl:param name="id"/>
  <xsl:variable name="query-template" 
select="document('../control/config/queries.xml')/gvs-site:queries/gvs-site:[EMAIL 
PROTECTED]/template"/>
  <xsl:value-of select="normalize-space($query-template)"/>
</xsl:template>
<!-- ===================================================================== -->

For reasons that I cannot think of, this does NOT work!

Interestingly, the following tag (which is essentially the "<!-- Get template-id -->" section of the fetch-template tag) will correctly read the template-id from the request: 

<!-- Get the Template ID from Request -->
<xsl:template match="gvs:get-it">
  <xsl:variable name="id">'<request:get-parameter name="template-id"/>'</xsl:variable>
  <xsl:copy-of select="$id"/>   
</xsl:template>
Also, If set the template-id to a static value in the fetch-template tag, it will return the correct template from the XML file.

So the questions I have are:
1. How can I get this to work? Are there any other suggested methods?
2. Why does the tag fail as it exists?
I'd be grateful for any answers/pointers to the manuals/old threads, etc. :)

Thanks,

Sreedhar
