I have made the similar project and faced the similar problem. But I managed to get the required data after proper filtering the String.

I have made tutorial video of that, have a look to the video understand the code I used for filtering and understand the logic also so that you can use it anywhere in future. I am attaching the link from the time I started explaining about the filtering process. Hope it helps you. If still have any doubt comment on that video I will come back to you
