passing parameters to a specific xslt stylesheet, with data from /request/parameters

Hi everyone,
I'm trying to put data from /request/parameters into a call to a
specific xslt stylesheet. I'm a newbie in Orben Forms, and I tried
something like the following without any good results:

  <p:processor name="oxf:request">
    <p:input name="config">
      <config>
        <include>/request/parameters</include>
      </config>
    </p:input>
    <p:output name="data" id="request-info"/>
  </p:processor>

.... (here I generate an xml data: "xml-data") then I tried:

  <p:processor name="oxf:xslt">
    <p:input name="data" href="#xml-data"/>
    <p:input name="config">
      <xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:import href="file:///specific/my.xsl"/>
        <xsl:param name="a_param"
select="#request-info#xpointer(string(/request/parameters/parameter[name='some_param_name']/value))"/>
      </xsl:stylesheet>
    </p:input>
    <p:output name="data" ref="data"/>
  </p:processor>

Finally I got: "Failed to compile stylesheet. 1 error detected."

The my.xsl stylesheet only process the format of #xml-data's content,
but I need to pass a parameter to it which must based on information
retrieved from /request/parameters. How can I accomplish this?

Edgard.

Edgard,

I have attached an example of how to retrieve the username of the
logged in user from the session. Hope this helps.

The following code above won't work:

 
select="#request-info#xpointer(string(/request/parameters/parameter[name='some_param_name']/value))

The XSLT @select attribute must be a valid XPath expression. Here, you
are using something that looks like an XPL URI instead.

But what you can do is add your own input on oxf:xslt:

  <p:input name="request" href="#request-info"/>

Then, you can access this from within XSLT:

   select="doc('input:request')/request/parameters/..."
