Hi everyone,
I would like to modify the doSave method in order to save the diagram
as an xml document. How can I do this?
Thank you

Gary,
You can't really compare JDOM and JAXP :)
I think this artcle explains it rather nicely (rather dated, but still
mostly valid)
http://www-106.ibm.com/developerworks/xml/library/x-jaxp/
Hope this helps,
Brian.

hi,
you can do this in the doSave() Methode very simple by using the standard
XML APIs.
Here is s short example:
/****************************************************/
import java.io.ByteArrayOutputStream;
import org.eclipse.core.resources.IFile;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
......
public void doSave(IProgressMonitor monitor) {
try {
ByteArrayOutputStream out = new ByteArrayOutputStream();
XMLModelParser.saveModel(out);
// create XML DOM Tree
DocumentBuilderFactory domFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
Document doc = domBuilder.newDocument();
// Insert the root element node
Element element = doc.createElement("root");
doc.appendChild(element);
// Insert a comment in front of the element node
Comment comment = doc.createComment("a comment");
doc.insertBefore(comment, element);
// Add a text node to the element
element.appendChild(doc.createTextNode("D"));
// Add a text node to the beginning of the element
element.insertBefore(doc.createTextNode("A"),
element.getFirstChild());
// Add a text node before the last child of the element
element.insertBefore(doc.createTextNode("C"),
element.getLastChild());
// Add another element after the first child of the root element
Element element2 = doc.createElement("item");
element.insertBefore(element2,
element.getFirstChild().getNextSibling());
// Add a text node in front of the new item element
element2.getParentNode().insertBefore(doc.createTextNode("B "),
element2);
// Prepare the DOM document for writing
Source source = new DOMSource(doc);
Result result = new StreamResult(out);
// Write the DOM document to the outputstream
Transformer transformer =
TransformerFactory.newInstance().newTransformer();
transformer.transform(source, result);
// save outputstream to IFile....
IFile file = ((IFileEditorInput)getEditorInput()).getFile();
file.setContents(new ByteArrayInputStream(out.toByteArray()),
true, false, monitor);
out.close();
} catch (Exception e) {
e.printStackTrace();
}
