Here you have you'll have to use vendor:node-set() function to change from
rtf to nodelist

define in your xsl:stylesheet the fn namespace:
<xsl:stylesheet ...  xmlns:fn="http://exslt.org/common";>
 ...
 <xsl:for-each select="fn:node-set($values)">

>     <xsl:for-each select="$values">
>       <xsl:value-of select="$keyValue"/>-<xsl:value-of 
> select="name()"/>
>     </xsl:for-each>
>   </xsl:template>
> </xsl:stylesheet>
> -----filter.xsl---------
> 
> --------shell output------
> [;] xalan -IN data.xml -XSL filter.xsl
> 
file:.../filter4.xsl; Line #23; Column #33;  XSLT Error
(org.apache.xpath.XPathException): Can not convert #RTREEFRAG to a NodeList!
