XSLT; parse escaped text into node-set and extract subelements

I've been struggling with this problem all day and I'm almost ready to end.

I have an XML file where certain pieces of data are stored as escaped text, but are themselves well-formed XML. I want to convert the entire hierarchy in this text node to node-set and extract the data in it. No combination of variables and functions that I can think of works.

As I expected it will work:

<xsl:variable name="a" select="InnerXML">
<xsl:for-each select="exsl:node-set($a)/*">
    'do something
</xsl:for-each>

InnerXML input element contains form text

<root><elementa>text</elementa><elementb><elementc/><elementd>text</elementd></elementb></root>

but it doesn't really matter. I just want to go to the xml like a normal node-set.

Where am I going wrong?

If you can use Saxon 9.x , it provides a saxon: parse () function to do this.

what i did has a msxsl script in xslt (this is in windows .NET environment):

  <msxsl:script implements-prefix="cs" language="C#" >
    <![CDATA[
    public XPathNodeIterator parse(String strXML)
    {
      System.IO.StringReader rdr = new System.IO.StringReader(strXML);
      XPathDocument doc = new XPathDocument(rdr);
      XPathNavigator nav = doc.CreateNavigator();

      XPathExpression expr;
      expr = nav.Compile("/");

      XPathNodeIterator iterator = nav.Select(expr);

      return iterator;
    }
    ]]>
  </msxsl:script>

then you can call it like this:



<xsl:variable name="itemHtml" select="cs:parse(EscapedNode)" />

and this variable now contains xml, you can iterate through
