feature access with mapscript ? functionnality of mapscript ?

[Xavier Mauclaire]

Hi
 
I'm using Mapserver do draw layers comming from either PostGis or shapefile
and i would like using mapscript to perform actions like :
 
    Zooming to a selected feature (feature selected by data attributes
stored in the database)
    Allowing a feature sequential access to get feature extent for example.
 
Doing theses thinks with mapserver with avoid writing one piece of code by
source type (postgis, shapfile) and so using external libraries.
is it possible with mapscript ?
 
 
regards
