[OpenLayers-Users] some questions about popup extent & hyperlink

[beppe]

Hi,
I'm an italian OL's newbie, I come from a mapserver world and I'm very
happy to discover every day something about OpenLayers!
I've this code [1] and this mapfile [2], the geographic elements are
stored in a postgis table.
The code works but in the popup window, info are displayed like this:
"GetFeatureInfo results: Layer 'ut' Feature 78: paese = 'Coredo'
localita = 'S. Barbara'"
Obviously I don't want info about "GetFeatureInfo", "Layer" and
"Feature", but only about "paese" and "localita".
The info, then, are print like a "text string". I'd want print the info
in table style...but I don't know how !!!

Question 2.
I'd like to have in popup an hyperlink to a page in wich print a map
with the extent of the selected feature, but:
1. my feature are point
2. I don't know how write the code!!!

Any ideas, example or tutorial?
thanks
