Extracting text info from existing PDF files

Hello All, 

I am attempting to extract text and position information from a PDF file
but I am having some difficulty. I have tried to use PDF::API2 however
it seems to be more aimed at creating PDFs as apposed to extracting
info from them. I will look at CAM::PDF next however I was wondering
if anyone  may have experience extracting info from PDF files and that
may have an example or some advice.

Thanks in advance
Brian
