[Xsltforms-support] parsing XPath expressions

[christophe g. <chr...@e-...>]

Dear Alain and all

I have done some tests with the xsltforms library today to see what would be
the amount of work necessary to port my xForms application (currently runing
under with the mozilla plugin) to xhtml forms. there are part of code that
will need to be refined (css mainly, I fear), but it seems more or less in
control.

But, first of all - the xsltforms library and concept looks great and it is
a real relief to see xforms solutions coming out! And the fact that
xsltforms is integrated with eXist is also a really good new.

There are a couple of errors thrown while xpath code is being processed that
I don't quite get however (as I think it is valid xpath, or at leat, it was
recognized so with the FF plugin). I use the latest code downloaded from
sourceforge, and FF 3 under a linux distribution) and, by the way am not in
a hurry as I will continue to use the FF plugin for development and switch
to xsltforms a bit later.

Cheers
Christophe
