Comparing Pages and Returning Differences as Regular Expressions

[matt cook]

The concept - a HTML file changes regularly. However, only certain
parts of the page change. I want to find a regular expression that
describes that changed area.

Can anyone here think of a rough way to go about this? I'm thinking
grab the page once a day, put it in a table with a date stamp, and
then do something.

How about using the power of PHP? no HTML file at all, instead use PHP
to dynamically generate the webpage every time it's requested from the
webserver... you could objectify the webpage to your hearts desire and
have any or all parts of it change for any given time interval.

I think this is beyond regular expressions. You probably need unix
"diff". You can easily call that command by calling shell.
