List of Xpath functions supported by Jackrabbit
Hi,
Does anyone know where I can find the list of Xpath functions supported
by jackrabbit?
Whenever I try to use some Xpath functions(like fn:contains,etc) to
query my jackrabbit repository,
I get an exception saying the function is unsupported.
It would be really helpful if somebody can point me to the appropriate link.
Thanks in advance.
Regards,
Prakash

that is correct, and Jackrabbit does not implement all Xpath (2.0)
functions, but in Chapter 6.6.6 (XPath Grammar) you can see the minimal
set of functions that are required to be implemented

yes, but see 6.6.6 for the minimal required parts

As is indicated in the spec. Some functions are implemented in
Jackrabbit which are not mentioned as required in the spec, though I am
not aware of a list of these functions

jackrabbit supports all of the required and optional functions in the JCR 170
specification. but that still excludes a lot of functions defined in the XPath
specification.

Hi Ard,
Thanks for your response. The jsr-170 spec says that the implementation
may not implement all the Xpath functions.
Its up to the implementation to decide what functions to implement and
what not.
There are whole lot of functions in Xpath that are not implemented in
jackrabbit.

Prakash

Think you mean jcr:contains instead of fn:contains. Furthermore, did you
take a look at jsr-170 [1]. In the spec you can find the Xpath features
implemented in Jackrabbit. Jackrabbit has some additional Xpath features
implemented, but I am not sure wether there is a list of these features
