Could you send a better description of the string being searched? 
Perhaps an example URL as well as what you are looking for?  I have
written quite a bit of code for screen-scraping pages, and think that
there has to be a better way than the approach of switching characters
to "%" symbols.  :-)

Usually, the splitting method is the best, but there are definately
plenty of things to try.  Just a little more info... :)
