[CS-FSLUG] Script for replacing a string in a html-document?

[Jukka]

Hi all!

I hope you don't think I am too lazy (which I well may be.. :). I have
170 similar html-documents with links pointing to a wrong directory
which I'd like to correct, but not "by hand" (I have done it once
already and it was tough...). Could someone give me an example-script
which replaces string in a html-document? I go to look something from
the net while waiting your responses.

Blessings,
Jukka
