RE: passing a string as a node list

Thanks, Maulik.  I changed to 2.1.0 but it broke all my parameters!  
2.0.1 is now working.

I don't quite understand your example though.  I gather that $chandoc 
is set externally to the template as a string of xml?  How is 
$evalparam being set, I though xalan:evaluate() would produce node list 
from a string containing xml tags?

I've been trying:

.......snip.......
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:xalan="http://xml.apache.org/xalan" exclude-result-
prefixes="xalan">
.............
<xsl:for-each select="xalan:evaluate($keywords)//*">
	<xsl:value-of select="./text()"/>
</xsl:for-each>
.......snip.......

where $keywords is a string containing:
<keywords>
 <keyword>
  find
 </keyword>
 <keyword>
  me
 </keyword>
</keywords>

which I was hoping would convert the string in $keywords to a node list 
and give me all the text in each node.  But it throws the exception:

Unknown error in XPath SystemId Unknown

Any hints would be great.

Thanks again,
Tim.
