Hello,

I am playing around with the Twitter API and I am trying to extract  
the hash tags from the updates. Something like this:

“This is the string that I want to pull #tags #out #of”

I have the regex that gets the tags, but I am not sure how to extract  
them from the string into an array.

Thanks in advance!

Pass the regex to String#scan, which will return an array of matches.  
Check  
the docs for details.
