select ... for xml, server side query from web page on vb

Hi,

I have a select like this:

select quarto "propr1",

(select  primo "prop2",

secondo "prop3",

terzo "prop4"

from mytable  for xml  path('Spesa'),  type)  "prop5"

 for xml PATH('precom'), ELEMENTS  XSINIL

that work fine on MS Managenent Studio.

I would like to obtein the xml result file on a web page and save it on client using vb.

Where can I find same examples? 

Many thanks in advance
