But it doesn't do all I wanted, at least not straightforwardly. I want them all! :-) That is, a list of all parameters for a name. With the two additions, I guess you could do that with a loop, but then, I have this something against mixing in Perl... In the interest of backwards compatability and maintaining relative simplicity, I guess it is best to keep that element like it is... :-) May I suggest an element, something like <param:get-all name="foo"/> that if given the query ?foo=bar&foo=baz will return <value>bar</value> <value>baz</value> Possibly, the name of the element (instead of 'value') could be an attribute too, and perhaps an optional element around these... > =head2 C<<param:count name="foo"/>> > > Returns the number of parameters provided on the request.

Hm, this returned 1 on me if I used multiple parameters with the same name. With different parameters, and no name attribute, it was correct. I'll try to look more about what could be the matter with that later (gotta run now (quite literally)). > This code is *completely* untested, since my development server has been > taken by my SysAdmin for some emergency server replacement work, Uhm, that's life... :-) I don't even have a separate development server (so I do most work on my workstation, and upload when I want others to have a look). > so if > anyone wants to grab the latest copy out of CVS and try it out, go for it. > If you do try it out, let me know if it works / fails, so I can release it > to CPAN or fix the bugs, respectively: Sure!
