How can one do this? In a previous message I noted that it was useful
for me to obtain w3c Documents from XMLModels.
I have a need to do the same on XML files stored in jar files. These
would be JDT JarEntryFiles hiding behind the IStorage iface. Since
these are readonly and never change I assume that such models would be
unmanaged.
But IModelManager is geared towards source found in IFiles. Any ideas?

A feature request is always good, since even if we don't implement, or implement exactly as requested,
we'd have better "data" on how people are thinking of using it, and could attempt to
satisfy.
I'd also be interested in more details of how/why you are using the model. As you discovered,
it creates a DOM model regardless of if valid or well-formed ... it really is for editing DOM's, where
the DOM would be expected to be illformed at various points. So ... just curious, what
features or aspects do you find benificial in your "project builder" context?
Thanks.

Easy, the document offsets for the artifacts in the file (tag name.
attribute value etc). I'm creating markers when I encounter errors and
the line:column offsets obtained from XML parsers are less than ideal
for this task. I spent a lot of time hacking the Xerces parser to get
good offset info but it's a hack for sure.
If wtp and sse can give me a dom interface *plus* the added extra info I
need then I'm quite happy to discard my old hacks! Besides, then I don't
have to maintain my hacks anymore ;-)
My stuff was depending on other open source projects for custom DOM
validation, XML parsing, and structured documents. WTP seems to give me
all that and more.

Noted. thanks. I have no need to modify the contents (indeed how would
one modify a readonly IStorage).
