Any DOM Node can give you its owner document using
Node.getOwnerDocument(), but you can also ask the editor for its
org.eclipse.wst.sse.ui.internal.provisional.extensions.ISour ceEditingTextTools
adapter and cast the result to
org.eclipse.wst.xml.ui.internal.provisional.IDOMSourceEditin gTextTools.
That interface provides a method to obtain the DOM Document.

The current model is on DOM Level 1 API compliant, it doesn't implement
all of DOM Level 2 and none of DOM Level 3. DOM Level 3 implements the
getTextContent(). You can use getNodeValue() or another DOM Level 1
api to get the information.
If you need DOM Level 2 and Level 3 support, I would suggest opening a
bug report to ask for it.
In the meantime, you can make an equivalant function by following the
example at the end of this article:

That's how it should be. The documentation for getNodeValue()
specifies a null result for certain Node types.

Correct. The following link gives a list of when something can return a
non-null value getNodeValue();
http://www.w3.org/TR/REC-DOM-Level-1/level-one-core.html#ID- 1950641247
If it's an element node, you are working with, then you must check to
see if there are descendants, the textual value if there is any will be
available in the returned Text node.
For the most part the way the DOM is implemented in WTP, is valid and
correct. However, out of 500 unit tests, there are about 150 of them
that the current DOM Level 1 doesn't pass.
See bug 214439 (http://bugs.eclipse.org/214439) for more information.
Most of these are probably edge cases, and in one particular case a
wrong assumption on whether Attributes can contain nodes. They can
according the spec, and the nodes are Text or entity nodes.
