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

Howdy Brian and all,
I'm interested in this also.
You suggested using JDom. I looked over some of the ways to save an XML
document (including JDom) and picked JAXP 1.3. I'm using it because it
comes with J2SE 5.0 and includes the recent XML and XSLT stuff from
Apache. My work uses XSLT to transform the XML.
Did I choose poorly?
Thanks,
Gary

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();
}
