   I am getting this strange problem. Let me give my xml and script function before I explain my problem.

   my xml:

		<book>My book Title</book>
		<pencil>My pencil length</pencil>
		<pen>My pen color</pen>

  my xslt:
	<xsl:stylesheet version="1.0" xmlns="" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:scrdt="urn:reval-com:scripts:datatypes">
	<xsl:template match="/">
			<xsl:call-template name="callInit">
				<xsl:with-param name="itemNode" select="."/>
	<xsl:template name="callInit">
		<xsl:param name="itemNode"/>
		<xsl:value-of select="scrdt:init($itemNode)"/>				
      <msxsl:script language="JScript" implements-prefix="scrdt"><![CDATA[
	function init(itemNode)
		if( !itemNode.length) return "";

		var val = itemNode.item(0).selectSingleNode('book');

		//var val = itemNode.item(0).firstChild;
			return val.text;

		return "Error";


     So my problem is, when ever I transform my xml with this template, it is printing "Error". It seems like it is not able to get to "book" node when I use selectSingleNode("book"). But variety is when ever I access it as .firstChild, it is recognizing  the node  and printing the correct value. 

     I have no idea what is going on there. Any leads will be appreciated.
