This is the part of html result i am getting upon querying http://results.vtu.ac.in/ with usn=1kn06cs054.

I need to query the result table and store it in local database how can i query it using xpath. i need to store and display oputput as

Name=THONGAM DEEPAK SINGH  
Usn=1kn06cs054  
Semester=8  
Subject=Programming language  
Subject code=06cs846  
external-11  
internal-18  
total=29  
result = Fail  

I am new to parsing so not much idea about doing . solutions with code will be highly appreciated Thanks

What you get there can never be queried using XPATH, it's not valid XML.
