I've been getting at the DOM via the StructuredModelManager:
IStructuredModel editModel = null;
try {
//retrieve a reference to the file being edited
IFile file = [TODO: get IFile here];
//get the model manager
IModelManager modelManager = StructuredModelManager.getModelManager();
//open the model for edit if making changes, if you only need read-only
access to the model, you could use getModelForRead(IFile) instead.
// Alternatively, use modelManager.getModelForEdit(IStructuredDocument)
if you have a reference to the IStructuredDocument instead of the IFile.
editModel = modelManager.getModelForEdit(file);
//cast the structured model to a DOM Model
IDOMModel domModel = (IDOMModel)model;
//get the DOM document from the DOM model
Document doc = domModel.getDocument();
//TODO: perform the edits to the DOM here
} finally {
//release the model from editing
if (editModel != null) {
editModel.releaseFromEdit();
//or editModel.releaseFromRead() if opened for read
}
}

Thanks Eric, thats somewhat what I needed. The problem is I have an
ITextSelection with the line text, I need a node from the selection, so I
can walk up it to find the parent tag. My problem with getting the whole
DOM is I dont know where the line text is in the DOM to start walking up....
Hope that makes sense.
Anyone have anyother ideas?
Thanks

As of 1.0M8, you'll find that the StructuredTextEditor's selection
is both ITextSelection and an IStructuredSelection of DOM Nodes (for
DOM models, anyway).
