TextFinder library download?

Hi, I am building an RSS arduino reader which will display data to LED diodes, I am using sample code from

Anyway when I compile the code i get the error ‘TextFinder’ does not name a type
I think that is because I lack TextFinder library(#include <TextFinder.h>), I cant download it from arduino website, can someone help me and upload it somewhere?
