I have been told that i can use xalan:evaluate function, but i cannot 
get it working. I am using xalan. I got the following error :

processor.javax.xml.transform.TransformerException: Prefix must resolve 
to a namespace: 00:00

I did declare the namespace as follows :
<xsl:stylesheet version="1.0" xmlns:xsl= 
"http://www.w3.org/1999/XSL/Transform"; 
<http://www.w3.org/1999/XSL/Transform> 
<http://www.w3.org/1999/XSL/Transform> xmlns:xalan= 
"http://xml.apache.org/xalan"; <http://xml.apache.org/xalan> 
<http://xml.apache.org/xalan> exclude-result-prefixes="xalan">

> Would appreciate if someone can help me solve this problem.
