Hi,
I have the following code :
<xsl:template match="/">
<xsl:variable name="target-dcr"
select="document('file:///C:/cygwin/home/zaphod/iwmnt/iceAG/main/US/IMC/WORKAREA/US_IMC/templatedata/Category/IndustryOverview/data/aerospace-and-defense')"
/>
<xsl:for-each select="$target-dcr">
<xsl:message><xsl:value-of
select="/ewcm:IBMWebContent/ewcm:Metadata/ewcm:Identifier"
/></xsl:message>
</xsl:for-each>
<xsl:variable name="tmp"
select="java:services.ice.teamsite.XPathUtil.getNodeFromXPath($target-dcr,'/ewcm:IBMWebContent/ewcm:Metadata/ewcm:Identifier')"
/>
</xsl:template>
where XPathUtil.getNodeFromXPath is defined as follows :
public class XPathUtil
{
public static Node getNodeFromXPath(ExpressionContext xslContext,
Node rootElement, String xpathExpr)
{
NodeList nl;
try{
PrefixResolver prefixResolver =
xslContext.getXPathContext().getNamespaceContext();
System.out.println(prefixResolver.getNamespaceForPrefix("ewcm"));
nl =
XPathAPI.eval(rootElement,xpathExpr,prefixResolver).nodelist();
// dies here
System.out.println(nl.getLength());
return nl.item(0);
}catch(TransformerException te){
te.printStackTrace();
}
return null;
}
}
The XSL produces the following output :
file:///c:/cygwin/home/zaphod/cloning/code/template-handlers/CategoryTemplates.xsl;
Line #38; Column #17; a1000038

I'm not sure what I am doing wrong. Any ideas?
Thanks,
