Match only "www.example.com" but not "www. some text"

Question

Need regex to match links like www.example.com in an html/text-string but:

not match "www. some text after"
not match "www" only such as "some text before www some text after"
not match link with http
must start with white space (\s) or not character before such as: " www.example.com" or "www.example.com"

I tried with:

'/(^|\s)(www[^\s].[^<> \n\r \s]+)/iex'

but also match "www. some text after"

doesn't have to be regex: http://stackoverflow.com/questions/6806929/is-url-valid-or-not — a3f, Jan 14 '13 at 11:28
Try with text: "Well, www is strange word but www. is closer to my mind.". You will see that "www." is matched too, but I don't need it. — Branislav, Jan 14 '13 at 11:33

You were looking for

/(^|\s)(www[^<>\s]+)/

\s includes \n,\r

You can also use (?<=^|\s)(www\.[^<>\s.]+\.[^<>\s.]+)(?=\s|$)

Much better, but still match "www. some text after". Don't know why. – Branislav Jan 14 '13 at 11:28
OK. This is working for me, based on your proposal: (^|\s)(www\.[^<>\s]+)/iex – Branislav Jan 14 '13 at 11:47
