与正则表达式匹配的链接

Question

I want to match link with regex until first space or < occur. I tried this regex

\b(((http|ftp)(.)?\:\/\/)?(www\.)?example\.com([^\s|<]+)?)\b

But the problem with this regex is that it is also matching example.com.au. So what i want to match

example.com                      // match
example.com/somelink/link        // match

example.com.au                   // do not match
example.com.au/somelink/link     // do not match

match till first space or < occur

Answer 1

Here's a solution that will match http://example.com/whatever but not http://example.com.au/whatever.

/\b(((http|ftp)(.)?:\/\/)?(www\.)?example\.com(?!\.[\w\d])(\/[^\s<]*)?)\b/

This was tested against this text:

Match http://example.com/ but not http://example.com.au
This is a sentence about http://example.com/.
http://example.com<
http://example.com/asdf.asdf.asdf/ asdf
http://example.computer

It uses a negative lookahead to specifically exclude example.com followed by \.[\w\d].
