Subject: [xsl] Nodesets as parameters From: "Hunsberger, Peter" <Peter.Hunsberger@xxxxxxxxxx> Date: Tue, 23 Oct 2001 09:46:25 -0500 |
Hi all, let me try this again. I want to pass the XSL parser a parameter that is nodeset. I believe that in theory this should be possible? I know variables can be nodesets, I'm assuming parameters can also be nodesets? Based on this assumption, I'm attempting to build a document fragment and then call the parser: org.apache.xalan.stree.DocumentFragmentImpl parmDoc = new org.apache.xalan.stree.DocumentFragmentImpl( ); for( Enumeration pr = data.getValues(); pr.hasMoreElements(); ) // Get next parameter value { String prn = (String)pr.nextElement(); // Get the parameter name Element parmE = parmDoc.createElement( prn ); // Create an element with that name parmE.setAttribute( "value", data.getValue( prn ) ); // Set the value for the element parmDoc.appendChild( parmE ); // Add the new element to the doc fragment } parmDoc.setComplete( true ); transformer.setParameter( "my-parms", new org.apache.xpath.objects.XNodeSet( parmDoc ) ); transformer.transform( xmlSource, new StreamResult( response.getOutputStream( ) ) ); When I attempt to reference the resulting parameter the parse just hangs and does not return. I suspect that either I should not be using a DocumentFragmentImpl or that I'm missing something in the construction of the fragment. The second theory is somewhat validated by the fact that the call: parmDoc.getDocumentElement(); which should return the root value for the fragment returns a null value! However, I see no way to add anything to the document fragment except by using appendChild, so I don't see any way around this? Anyone have any ideas?
