I want to take a Twitter text like this:

s = "Today 09/07 sunday http://t.co/123 - AC/DC COVER Opening and DVD - woman R$10 / man R$15. - http://migre.me/59qwc"

and turn it into this..

s = "Today 09/07 sunday LINK - AC/DC COVER Opening and DVD - woman R$10 / man R$15. - LINK"

This snippet is failing for some reason, please, some help

s.replace(/(http\:.*)\s/g , 'LINK')

Try using

/\bhttps?\:\S*/ig

which uses \S* to match runs of non-space characters so won't have problems matching at the end of input where there is no following space.

This should strip HTML from your text

s.replace(/<.*?>/g, '');

As stated, .* will match whitespace and thus replace everything. Depending on the system you are using, you may be able to get away with something like \S*, which matches only non-whitespace characters, or else a more explicit [^ ]* instead.

.* will eat all, including whitespace, so this finds everything, until it cannot go further, then it backtracks to find the single whitespace character. You'll have to match only non-whitespace characters for the URL and you will be done.
