If you're using MSXML, then you can write Javascript code in an <msxsl:script> block which you can invoke from an XPath expression during the course of the transformation (look up "extension functions"). This Javascript code can invoke the MSXML parser on your escaped string and pass back the resulting DOM tree.

I'm using .NET 1.1...
Does it uses MSXML or has its own implementation?

If you're using System.Xml.Xsl in .NET then there's some material on writing extension functions at

I've not played around with this stuff in .Net yet so I was curious so I knocked together the following sample:

XML File to be processed:

Code:

<?xml version="1.0" encoding="utf-8" ?> 
<root>
    <child>
    &lt;element att="value"&gt;one&lt;/element&gt;
    </child>
</root>

XSL Transform File:

Code:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" 
    xmlns:my="http://www.wackylabs.net/dotnet" 
    exclude-result-prefixes="my msxsl">

<xsl:output indent="yes" />

<msxsl:script implements-prefix='my' language='C#'>
  <![CDATA[
  public XPathNavigator ParseXml(string xml)
  {
    System.IO.StringReader sr = new System.IO.StringReader(xml);
    XPathDocument doc = new XPathDocument(sr);
    return doc.CreateNavigator();
  }
  ]]>
</msxsl:script>
<xsl:template match="child">
    <child>
        <xsl:copy-of select="my:ParseXml(string(.))" />
    </child>
</xsl:template>

</xsl:stylesheet>

The output, after running through XslTransform:

Code:

<?xml version="1.0" encoding="utf-8"?>
<child>
  <element att="value">text here</element>
</child>

I hope this gives you a good starting point for your own code.
