XSL Script for XMetal2.1

Hi,
I was wondering if any of you have experience with writing XSL scripts
for XMetal2.1 , for preview in HTML function? I am trying to write a XSL
script for this purpose and I would like to know how I can pass
parameters to XSL script, so that I can view the HTML output for a
specific page, instead of seeing the whole document.

Thanks for your help.

---------XSL Script---------

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
	<xsl:param name="moduleNum"/>
	<xsl:param name="sectionNum"/>
	<xsl:param name="screenNum"/>

JavaScript Macro I use within XMetal
-------------------------------------------------------------------
// This macro gets called when the user has selected Page Preview view,
  // or Preview in Browser.  The BrowserURL property is the URL that
will 
  // be passed to the browser.  On entry, it contains the URL of a
temporary
  // copy of the XML file being edited.  We apply an XSLT stylesheet to
create
  // an HTML file and set BrowserURL to be the path to this file.
// This macro illustrates the use of the MSXML component to do an
// XSL transformation.  Note that the version of MSXML that ships
// with IE5 is not compliant with the final recommendation of the
// W3C XSLT working group.
