please be gentle, I'm new to Python. I've installed several modules, but cant find one that fits my needs. Maybe you can point me to the right one.

I want to search an already text-searchable PDF for a certain pattern ([A-Z][A-Z][0-9][0-9][0-9][0-9]) and it should give me back all the locations (X1,Y1,X2,Y2).

Is there anything similar to this that I could use?

Thanks!
