[pdt-dev] Using ModelQueryExtension

["Jim Kremens" <kremens@xxxxxxxxx>]

Hi all,

I'm trying to extend PDT to support custom html tags and attributes.
After some confusion,  I've implemented the
org.eclipse.wst.xml.core.modelQueryExtensions extension point and
built a class that extends ModelQueryExtension (thanks for the tip
Roy!):


package org.fhtml.eclipse.editors;

import java.util.ArrayList;
import java.util.List;

import org.eclipse.wst.xml.core.internal.contentmodel.modelquery.extension.ModelQueryExtension;
import org.w3c.dom.Element;
import org.w3c.dom.Node;

public class FhtmlModelQueryExtension extends ModelQueryExtension {

       public FhtmlModelQueryExtension() {
               System.out.print("NEVER CALLED\n");
       }

       public String[] getAttributeValues(Element e, String namespace,
String name) {
               //See XSDModelQueryExtension for an example
implementation of this...
       }

}


But my class is never invoked.  I've looked at other implementations
of ModelQuery, like in the XSD and JSP packages, and unfortunately, I
can't discern when these extensions are actually called.

Has anyone had success with this extension point?  Also, if anyone
knows of any real documentation on the topic, that would be great as
well.  As far as I can tell, there's almost nothing, as this is meant,
for now, to be an internal extension point.

Thanks,

Jim Kremens
