   The simplest way is to simply serialize the DOM on the
client
(printNode, DOMUtilities.writeNode) and use
'postURL'/XmlHttpRequest(?)
(JS functions) to send it back to the server.  I don't know
what client 
you are using (Batik, ASV, Opera, FF), so I can't provide
real details 
but that should get you started.

Good to hear that, as that is the road I have started down,
hoped it was
the correct method.

Will post back with any useful snippets for future
reference.

Thanks as ever,
Dylan

Hi,

A bit of extra advice gratefully received....

I've got my DOM serialized and posted back to the server,
I'm now trying
to update my initial SVG doc with the new DOM (or create a
new doc)..

So my initial SVGDocument is something like....

<?xml-stylesheet type="text/css" href="http://blah/blah.css&
quot;?>
<?xml-stylesheet type="text/css" href="http://blah/blah.css&
quot;?>
<svg contentScriptType="text/ecmascript.... etc
etc>
<old stuff />
</svg>

And my new Node to overwrite the previous is...

<svg contentScriptType="text/ecmascript.... etc
etc>
<new stuff />
</svg>

And I thought I could call something like..

doc.replaceChild(oldDocNode, newDocNode);
or
doc.importNode(newNode, true);

But I'm getting various errors with the various combinations
of
parameters/methods I'm trying. I guess what I am trying to
do is very
simple, and I can't see the wood for the trees...

Any tips greatly appreciated,

Dylan.
