String comparisions

[Talib Hussain]

Experts,

I have a requirement of comparing string and getting the difference out

For Example :

strOne = "Hello, this is a test"
strTwo = "Hello, this is a test forum"

This should result that word "forum" is extra.

Any thoughts?

strTwo.split(strOne)[1].lstrip

But that's very specific.

just for that instance:
p (strTwo.split - strOne.split).join

Look into the ruby full-text search.

IMHO your question is by far not specific enough. What kind of output
do you expect exactly? Do you want all _words_ reported that are
missing or extra? Do you have to have _substrings_ reported which are
missing or extra? Do you need _positional information_ with that? If
so, which (word position, character position)? Do you need human
readable output or do you want to automatically process it? etc.
