XPath and Perl data structures (Score:1)

by rob_au (1845) <rob.caseyNO@SPAMbluebottle.com> on 2003.11.13 7:17 (#25746) Journal

I've been working on a XPath-like expression language for Perl data structures using Barrie Slaymaker's EventPath grammer which was based on James Clark's XPath grammer. I can now say /this/method::foo(/that)[@can="dance"] and get back any objects returned from the foo method of /this called with /that, and select those returned objects that can('dance'). Eventually I'll factor most of the code out and put it on CPAN as Data::DPath.
After reading this journal entry, I thought you might find it interesting to take a look at Class::XPath [cpan.org] by Sam Tregar [perl.org] - This syntax for walking object trees has also been discussed previously on Perlmonks in this thread [perlmonks.org].
