XML generation in Pig

[DIPESH KUMAR SINGH]

Hi,

I have data in a file which has schema, say like this: (stud_id, Physics,
Chemistry, Bio, CS)

I need to generate an output which should contain (stud_id , xml_payload)
for each record in my relation.

The type of dynamic xml i need to generate is like this:

<stud xmlns: www.w3.org .... ... >
   <stud_id> A-12 </stud_id>
   <subjects>
         <marks>
               <phy> 98 </phy>
               <chem>96 </chem>
        </marks>
   </subjects>
</stud>

<stud xmlns: www.w3.org .... >
   <stud_id> A-102 </stud_id>
   <subjects>
         <marks>
               <phy> 98 </phy>
               <chem>96 </chem>
               <CS> 100</CS>
        </marks>
   </subjects>
</stud>

Any suggestions on how to proceed on this? I am bit new to pig.

Thanks & Regards,

Dipesh
