automatically identify patterns. (RegEX)

[Idan.Yael]

hi all,
i would like to know if there a software on the net i can download
which can identify text patterns between text files...
meanning:

if i have 10 files and i want to compare those files and find their
tamplate translated to a regular expression string.

for eample,
lets say i got a news site with holds an index of all the news
published.
i want to take 5-10 pages and declare the sections that i know supposed
to be diffrent between the files.
the software will then run on the files and give me the regular
expression to identify the pages i got and get the "changing text" in a
group ( "(<text>)" ).
so that way i can just scan the site and know about all the urls that
match this regular expression tamplate.

i know this is alot to ask for but i though i might give it a try and
ask before i start coding myself

thanks in advance for any answer,
Idan.

Don't do software requests. I think every decent text editor has some kind
of file compare functionality, though. Or you can always just get diff.

Even assuming you mean a template, what does "translated to a regular
expression string" mean to you? Clickety-click regex trick? I'd like
something to write my regexes for me, too. In fact, it would be nice if it
did all my coding so I could nap some more during the day... : )

If they all have the same template, then why not just use diff? It's
certainly not a hard task to run the command, read the output, parse out the
lines you need and then extract them from a file (finding the start and end
delimiters for the changed text will be the trick).
