compare two string and get the difference

[jyoti]

Hi there,
I am trying to compare two strings and get the differenc
in vbscript.

Example: Str1="This is a test text"
Str2="This is a fine test text but a little long"
I like to compare str1 with str2 and get the difference.
Above example the difference will be "fine" and "but a
little long"
How do I do that? A sample code would be apprciable.

Thanks for your time

actually that isnt' the "difference ". Technically you'd have to do a
position by position check or a word by word check, splitting it on the " "
(spaces) which isn't accurate really though.

There really is no direct way to get these differences directly. Could you
explain a little more on the idea you are trying to get to?

Thanks for your reply..

I am developing a web site content managment system for our
organization. Anybody changes anything on the content of the web site,
goes through a review process. When somebody make any update and upload
to pre-production area, the system sends an email to reviewer to review
the update. The email contains a URL where reviewer can view the updated
page.

I have two folders. One is original folder and the other one is Update
folder.

I like to highlight the updated area when reviewer visits the url to
review.

Example:
At Original Folder:
Test.txt file contains " This is a test text"
At Update Folder:
Test.txt file contains "This is a fine text blala"
I like to highlight the word "fine" and "blala".

I can go line by line and compare both files. If lines are different
then I can highlight the whole line on Test.txt on update folder. But
the problem is if line is too long and user makes just one or two words
update, then it will highligh the un-neccessary area.

Any suggestion..

Thanks for your time.

what I'm saying though is that

"Hello my name is Curt" campared with
"Hello There my name is Curt" doesnt' result in only showing "There" as the
difference. EVERYTHING from the word "There" on is different technically,
it's all shifted over one word.

I would say do a LINE comparison, just indicating that the LINE has changes,
but again, if anything shifts down a line EVERY line from that point on will
be "changed".
