Re: How to sort Using Dom and SelectNodes

Hi Karl,

With MSXML there is no method to sort nodes within the DOM. Your best bet
would be to create a simple XSLT (see below) to order the doc. The use code
something like:

var xmlUnsortedDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
var xmlSortedDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
var xmlSortXSLT = new ActiveXObject("Msxml2.DOMDocument.4.0");

... code to load the XML into xmlUnsortedDoc ...
... code to load the XSLT (see below) into xmlSortXSLT

// tranform the unsorted doc and stuff the resulting XML into a second DOM
xmlOrderedDoc.loadXML(xmlUnorderedDoc.transformNode(xmlSortXSLT));

... then get the required nodes with .selectNodes method

This XSLT should do the trick.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

 <xsl:template match="/">
  <xsl:apply-templates>
   <xsl:sort select="@order" data-type="number" order="ascending"/>
  </xsl:apply-templates>
 </xsl:template>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*">
    <xsl:sort select="@order" data-type="number" order="ascending"/>
   </xsl:apply-templates>
  </xsl:copy>
 </xsl:template>

</xsl:stylesheet>

Hope that helps

Malcolm
