I need to combine 2 XML documents into one.  The base document contains item specific
data and the second contains boiler plate text which needs to be accessed one node at
a time.  All the files reside on a PC hard drive.  I am using Stylus Studio 6
Professional Edition, Build 377m.


Snippet from base XML document:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="c:\drv_e\brl\database\tools\Spec_Doc\spec_trans_1.xsl"?>

<spec_doc src_file="item_spec.xml">

   <title_pg>

      <tp_header file_id="boiler_plate.xml"
                 element="/boiler_plate/branch_name"> </tp_header>
...

Transform stylesheet snippet for the above XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="xml" omit-xml-declaration="no"/>

   <xsl:template match="/">
         <xsl:apply-templates/>
   </xsl:template>

   <xsl:template match="/spec_doc">
      <fci_doc>
         <xsl:apply-templates/>
      </fci_doc>
   </xsl:template>

   <xsl:template match="title_pg">
      <title_pg>
         <xsl:apply-templates/>
      </title_pg>
   </xsl:template>

   <xsl:template match="tp_header">
      <xsl:variable name="filename" select="@file_id"/>
      <xsl:variable name="nodename" select="@element"/>
      <xsl:copy-of select="document($filename)/boiler_plate/branch_name"/>
   </xsl:template>
...

This format works and produces the output I want.  What I would like to do is
use the variable "nodename" in place of "/boiler_plate/branch_name".  I have
tried inserting $nodename in place of the node name, as in:

      <xsl:copy-of select="document($filename)$nodename"/>

but get the error message:
"Unexpected token in xsl:copy-of"
