[jdom-interest] JDOM and XSLTC.

[Cybrarian Rök]

Morning,

after diving a bit I suggest a so-so way to transform a JDOM Document
using XSLTC; finally I'going to implement this logic cause summer is
far away and I don't feel ready to JARmess my system before
next springtime ... RAAH!

the example code below is based upon Paul's suggestion;

-Cheers.

import org.jdom.*;
import org.jdom.output.SAXOutputter;

public class JdomDocumentToXsltcDomDOMImpl {
  public static void main(String[] args) {
    try {
      /* ... manipulation tasks ... */
      Element foo = new Element("foo");
      /* ... and so on ... */
      Document doc = new Document(foo);
      /* ... get a new DOMImpl ... */
      org.apache.xalan.xsltc.dom.DOMImpl domImpl =
        new org.apache.xalan.xsltc.dom.DOMImpl();
      SAXOutputter x = new SAXOutputter(domImpl.getBuilder());
      x.output(doc);
      /* ... pass the domImpl to any interested Translet ... */
      System.out.println("done! domImpl's size is: " +
        domImpl.getSize() + " nodes.");      
    } catch (Exception e) {e.printStackTrace();}
    System.exit(0);
  }
}
