Tried regexp - (http://(?:.)*?\\.) ((?:.)*?\\.) ((?:.)*?\\.) ((?:.)*?\\.) ((?:.)*?\\.)

But it is working for the first URL not for the second URL. Because I used this ((?:.)*?\\.) to check repetitive group of .(dot) with space. It doesn't seems to be worked for second URL. Is there any way to do such thing for all URL.

Answer 1

Unfortunately, this is not possible, unless you make assumptions such as require the URLs to appear at the end of sentences, end with .html etc. (and that is unreasonable, especially because all the links in your example don't appear at the end of sentence nor end with common suffix). To illustrate the reason why this is not possible, observe how you can't tell difference between:

A new site: http://example.com/ appeared.

and:

A new site: http://example.com/ appeared .

Answer 2

possibly something like this?;

list = str.split('http://search. atomz. com/search/?sp_a=sp01089f00&sp_f=iso-8859-1&sp_q=%22daily+eastern+news%22')
nlist = ''.join(list)
print nlist

which returns; http://search.atomz.com/search/?sp_a=sp01089f00&sp_f=iso-8859-1&sp_q=%22daily+eastern+news%22

You may need to complicate it with variables etc, since this is a barebones function..
