Problem in XSLT: Convert the Text value into a NodeSet

Question

I have a XML which has an element that hold a xml fragment within a CDATA, something like:

<node><![CDATA<root><child val="1"></child></root>]]></node>

now I need to parse this xml and get the value of "val" attribute. I have to use XSLT for this parsing. The problem is that normal xslt:copy-of select or xslt:value-of select is giving the value of "node" element with Type Text, which can not be parsed using XPATH. i've tried something like:

<xslt:variable name="NodeValue"><xslt:copy-of select="//node" /></xslt:variable>

and try to retrieve the value:

<xslt:value-of select="msxsl:node-set($NodeValue)/root/child/@val />

Please help me out if you've any other idea.
