Subject Re: JXPath over Generic Collection<?>, How?
Date Thu, 26 Feb 2009 06:53:08 GMT
Many queries don't work,  I can't get any results for the following (code
taken from previous email)...
        runEvaluation("/root/animal/cat/tiger[last()]", context); //absolute
& single
        runEvaluation("/root/animal/dog/*", context); //absolute & multiple
        runEvaluation("//dog", context); //deep search
        runEvaluation("//dog/*", context);//deep multiple
        runEvaluation("//cat/*[objectName='LION']", context);//deep filter

These are the really interesting benefits on xpath that I would dearly like
to have.

A Huge Thanks once again for your reply Matt!!! :)
