Hi @NishanthR,

As a basic guideline, it’s always advised to not share the code on forum.

As for your doubt, clearly there is some issue with the method. I am guessing you aren’t returning the strings you have extracted or aren’t extracting the string properly. Just check your code using a debugger and see which is the case.

Let me know if you need help!
