Help Comparing 2 Fields

I'm in them middle of developing an application that monitors a hand
full of web sites by comparing their content from one day to the
next. I'm using the Troi plug-in to capture the page content, and
bringing it into a text field.

I have 2 fields, TODAY's and YESTERDAY's before I get ready to move
the new content in, I move what was in TODAY to YESTERDAY and then I
bring in TODAY and do a simple If (TODAY = YESTERDAY) calculation.

That works fine for a majority of the sites that are being monitored.
However, today I found out that one of the new sites being added has a
stock ticker on it that gets updated daily. Since the ticker data is
not what needs to be monitored I don't care if that changes everyday,
except that it messes up my simple IF statement because now TODAY's
site does not match YESTERDAYS.

Each site monitored is different, what do you think the best possible
solution is to ignore the ticker changes ? I need to figure out a way
to add a tollerance to the if. Like if it's 90% the same, that's OK.
Is that possible ?

"Fuzzy" comparisons aren't possible in FileMaker. Even if it was possible,
how can FileMaker determine that the 10% that is different is or isn't what
you are interested in?

The only real way to achieve this would be to remove the "ticker" part of
the website from both Fields, but that would be very difficult unless there
is some way of determining where it starts and ends.
