repeating words

[dvdljns]

I need a script that will check a webpage and list all the words
that repeat and how many times they repeat and save that to a txt file.
Thought I saw one like it on javascriptsource but cannot find it now

JavaScript will not be able to save to a .txt file. You will have to use some sort of server-side language such as PHP or Perl to do this.
