Regex link matching on raw text

Anyone got any ideas how to match links from such string:

C#

"http://www.youtube.com/Vid56xtghhttp://vimeo.com/channel/id=14498http://rapigator.net/file/345gtrG/mike_goes_mad.avi"

Basically this string contains 3 links merged together. I need to separate it out somehow into 3 distinct links. Any way to do that with regular expression?

Thanks!

What I have tried:

Tried playing with regular expressions but without any luck. Not sure how to stop it when another "http(s)?://(www\.)?" block is reached...

By the hell, how did you end up with something as stupid as the 3 links in a single string ?

Simple - some sites have reference links in placed in comments and when I get the content - everything is mixed.

See solution 1 for a working solution.

This site can help to see if a regex is doing what you expect.
Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]

I guess you will have to read regex documentation to understand advanced usages.
perlre - perldoc.perl.org[^]

Valid question.
Good point with the Regex tools too.

Solution 1

You can try this

http:(?:(?!http:).)*

It will match from http: up to the next occurence, but not including it.
The result of your sample string will be 3 separate matches.

[UPDATE]
Forgot the https variant:

http(?:s)?:(?:(?!http(?:s)?:).)*

5ed.
This also boils down to our last comments. First response could be: what the hell is that input data with "merged links"? Should the purpose of programming be compensation of someone's idiocy? Maybe elimination of idiocy could be a bit more productive? :-)

Very true. Bad (or strange) input data seems to be very common.

I used this:
http(s)?://((?!(http)).)*
