Getting information server side

Hello I have a html table with info. I can get this info out of it with this little script, but how do I get this server side(ASP)? I need to get this into my xml database.

this script works. But this only works client side.

<script language="JavaScript">{
 function getActorAchternaam(nuber){
 var antwoord=(table.cells[(nuber-1)*2].innerText);
 return antwoord;}

any ideas how to do this?
