The code is

[http://pastie.org/341880](http://pastie.org/341880)

And i want it to return

nil  
www.yahoo.co.in  
/~testing/i.html

but when I run this code, why doesn’t the www.yahoo.co.in detected?

You might want to play with your regex on Rubular (http://  
[rubular.com/](http://rubular.com/))  
A little experimentation shows that you probably want to include  
‘http://’  
in your input string

cheers

the code should work for both, if there’s no http:// then it should  
print out:

nil  
www.yahoo.co.in  
/~testing/i.html

if there is then it should print:

http  
www.yahoo.co.in  
/~testing/i.html
