ethernet web server form version 23

Hi, i am currently working on a project which i need to enter a mobile number on a web page and then have that read by a cellular shield!

I was using text finder library which works fine in version 1 of the arduino software but i need to run my code through version 23 in order to make the cellular shield work. I have been looking around for a while to try and find a solution without posting but i have hit a bit of a brick wall.

Does anyone know another way of being able to read text entered into a web form?

Thanks a lot
