need advice on loading XML file

xmldocument load xml file
I have created an XML application for users to view information about
project datasets (www.nwcsr.com/meta).  The page works great, but the
data island takes quite awhile to load (5mb).  The current approach (in
XSL) looks like this:

function rewriteOtherFrame(xslURL, variable, datTbl) {
var curPattern =
curPattern.text = "codeBook/fileDscr[@ID='" + variable + "']";
myid.innerHTML = xmlData.transformNode(xslStyle.XMLDocument);
<xsl:attribute name="ID">xslStyle</xsl:attribute>
<xsl:attribute name="ID">xmlData</xsl:attribute>
<xsl:attribute name="SRC">metaman.xml</xsl:attribute>

My question:  Can I find a more efficient way to access this data
(easily) using DOM, or should I try a different approach?  I am leary of
using SAX2, because it looks like a big code rework would be necessary.
I did see a SAX example using MSXML 4 and scripting that had a quick
load time (below).

My last question:  Can I use transformNode or something else in the
example below to filter the XML file?

Thanks in advance, I am a XSL/XML newbie and appreciate the help,

   //Create the XSLTemplate object (xslt).
   var xslt = new ActiveXObject("Msxml2.XSLTemplate.4.0");

   //Create and load the stylesheet (transform1.xsl) as a DOMDocument.
   var xslDoc = new ActiveXObject("Msxml2.FreeThreadedDOMDocument.4.0");
   var xslProc;
   xslDoc.async = false;

   //Connect the XSLTemplate object to stylesheet DOMDocument.
   xslt.stylesheet = xslDoc;

   //Create XSLT processor using stylesheet for XSL template.
   xslProc = xslt.createProcessor();

   //Create and load sample XML file (books.xml) as a DOMDocument.
   var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
   xmlDoc.async = false;

   //Create SAX writer.
   var xmlWriter = new ActiveXObject("Msxml2.MXXMLWriter.4.0");

   //Assign XML sample file as input of the transform() method.
   xslProc.input = xmlDoc;

   //Use a SAX writer as the output of the transform() method.
   xslProc.output = xmlWriter;

   //Do transformation on the sample XML file.

   //Use SAX writer ouptut to generate inner HTML for page.
   result.innerHTML = xmlWriter.output;
