[xsl] An XSL question

["N Zhou" <zhou_naijun@xxxxxxxxxxx>]

Hi,

I have original xml data is:
<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection xmlns:gc="http://localhost/wfsschema/gc";  
xmlns:wfs="http://www.opengis.net/wfs"; 
xmlns:gml="http://www.opengis.net/gml";
>
   <gml:featureMember>
     <gc:ngs>
       <gml:boundedBy>
       	<gml:Box srsName="epsg:4326">
       	</gml:Box>
       </gml:boundedBy>
     </gc:ngs>
   </gml:featureMember>
</wfs:FeatureCollection>

I have an xsl as:
<xsl:template match="/">
 <Points>
    <xsl:for-each select="wfs:FeatureCollection/gml:featureMember">
       <Point>
          <gml:boundedBy>
             <xsl:attribute name="srsName">
           	  <xsl:value-of 
select="gc:ngs/gml:boundedBy/gml:Box/@srsName"/>
             </xsl:attribute>
         </gml:boundedBy>
       </Point>
   </xsl:for-each>
 </Points>
</xsl:template>

However, I cannot get the value of "srsName" in the transformed file. Can 
anybody help me?
It's a strange problem for me. I'm using XML::LibXSLT for the 
transformation, which has this problem. However, the xsl works perfect when 
I use XML::XSLT. I wonder if there is an error in my xsl file or the 
XML::LibXSLT?

Thank you very much!
