Denis,

Without using an intermediate control, it is complicated, I am not sure
how you can do this.

If you had a web service for your JavaScript and your web page to get
the
instance data from... It might be possible to use the default submission
to update (from javascript) instance data.

There would be side effects like what xforms events are fired (or not),
the page might refresh.

One instance containing the serialized text of another, plus a hidden
control
to hold the text, plus a way to create a DOM object in javascript
from the text
is the solution Orbeon designed.

Regards,
Hank
