Hello Jose,

Interestingly this is not the first time that DI has been asked about the possibility of using DISelect with other expression languages. I have some sympathy for this, given how awkward XPath expressions look inside XML documents.

Personally, I have no problem with enabling other expression languages for DISelect. The base reason for picking XPath initially was because it is what is used elsewhere in DIAL, in particularly in XForms. Hence, it makes perfect sense for that to be the expression language for DISelect used in DIAL. This is not necessarily the case in other potential uses of DISelect.

Right now, there is no particular group within DI pressing for additional expression languages, so its not likely to happen spontaneously. However, if W3C member companies wish to join DIWG, or its follow on after rechartering, to carry that work forward, I think that it could be easily accommodated in a future revision of DISelect.

By the way, I assume by JSP 2.0 you mean using those expressions in-line rather than embedding DISelect in a JSP or servlet. In that latter case you can, of course, already do this. I know I have!

Best wishes
Rhys

Dear all,

Does the current version of the content selection  standard allow to
include expressions in other languages than XPATH?  I'm thinking in
expressions expressed in Expression Language (JSP 2.0) for example.

Thanks and Best Regards
