No, it makes changes using the DOM interfaces (with help from
IDOMModel) as much as possible. Certain precise changes are often
done using the raw text, but this tends to be used mostly by
formatting and cleanup where whitespace is significant. Selection
and responsibilities such as saving are routed through the
StructuredTextEditor, though.

The design page is actually using the text document to obtain the
DOM model, Otherwise, it tends not to be used there.

Can anyone point me to these said DOM interfaces as im am so lost in how
the editor is making these changes. Closest I can find it is being done
through XMLModelUpdater, but it is in internal and I have no visibility to
use it.
Or am I missing the whole boat?
Basically what I am trying to do is make a multipage editor very similar to
the XSD editor, with source on one page and Gef on the next, when a change
is made in gef page, source knows about it, and same other way around. But
not knowing how to update the DOM, changes to the gef dont keep in sync with
the source.....
Sorry to keep asking the same thing but thak you for your time

No, in fact I got asked the same question just last week. The DOM
interfaces mentioned are the interfaces in the org.w3c.dom packages.
The XML model implements them to a reasonable extent. Changes
made to the model using the DOM interfaces are automatically
reflected in the text, and vice-versa, assuming the syntax is
well-formed. Most of your concern will be in keeping your GEF model
in sync with DOM changes.
