[Zope] Getting at form variables

I wanted that a url of the form 'http://url?a=b+c&d=e' produce a page like: [----desired-webpage---- You submitted: a = b c d = e ---------------------------] I have finally found the following way to do it:- [----dtml-snip------------ You submitted: <dtml-in "REQUEST.form.keys()"> <dtml-var sequence-item> = <dtml-var "REQUEST.form[_['sequence-item']]"> <br> </dtml-in> ---------------------------] Is there a neater/better way? More generally, given a dictionary called map and a string called key... <dtml-var map> prints `{a: 'b c', d: 'e' }` <dtml-var key> prints `a` ...is there a way to get at map[key] through DTML ? (`b c` in the above example) <dtml-var map[<dtml-var key>]> doesn't work. Thanks, Shalabh
