Hi all,

I am extending XML Editor of Eclipse.

Is it possible to access to DOM of the XML file opened inside the editor?
How?

Thanks
Marco

That depends on what you mean by extending the XML Editor. What do you
mean?

I am extending the content assist as I said in other posts.
I am working on org.eclipse.wst.xml.ui plugin and everything works fine.

I would like, if possible, get the DOM of the XML file opened inside the editor.

Thanks
Marco

So where from, exactly, are you trying to get the DOM, from the editor
class, or somewhere else?

Also, if you're changing org.eclipse.wst.xml.ui itself, the license may
place additional requirements on you, i.e.
http://www.eclipse.org/legal/eplfaq.php#MODDIST .

At the moment I am working on AbstractXMLModelQueryCompletionProposalComputer.

And, about license, I do not distribute the code to any others people, I will keep it only for me.

No. If you do not distribute the modified Program, you do not have to make your modifications available to others.

Thanks

Assuming you're in one of the methods with a ContentAssistRequest object passed in as an argument, the node and parent node in that object are part of the DOM model already. Otherwise it's really a question of what objects you have on-hand to work from.

At the moment I am working in addAttributeValueProposal to add proposal for attribute values.
Here so I have access to DOM in particular I have the current node, right?

But is there a way to have the DOM of the whole document?

Thanks

You seem to be using DOM in a generic sense while I'm using it to refer to the org.w3c.dom.* interfaces which we mostly implement, and those have clear means for getting the object that represents the entire document. Or do I misunderstand?

No no, like you, I mean to referring to org.w3c.dom Smile

I saw that for example, in addAttributeValueProposal an object org.w3c.dom.Node, is it right?
So at ervery call to the content assist I have an object containing that particular node, is it right?

Thanks a lot
Marco

Is it possible to build an XPath query on the current node?
I am trying to do that but probably I did errors somewhere; I am in "addAttributeValueProposals" and I have the "node" variable (org.w3c.node) which contains the current node.

If I do

XPath xpath = XPathFactory.newInstance().newXPath();
XPathExpression xPathTest = null;
NodeList o = null;

try {
    xPathTest = xpath.compile("//@*");
    o = (NodeList) xPathTest.evaluate(node, XPathConstants.NODESET);
} catch (XPathExpressionException e1) {
  e1.printStackTrace();
}
			
System.out.println(o.getLength() + " length");

I obtain the number of ALL attributes inside the node and not inside the current node, where I am wrong?
