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"

Answer 1

You were looking for

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

\\s includes \\n , \\r

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