Subject: Building an array of matching strings.

I want to search through a block of text and build an array of all
strings contained within this text that match a given pattern.  I know
the following hack will work, but it seems like a misuse of the gsub
method:

  # Assume that 'text' contains the block of text and that 'pat'
  # is a Regexp instance containing the pattern to match.

  matchingStrings = []
  text.gsub(pat) {
    |m|
    matchingStrings << m
  }
  
Is there a cleaner and elegant way to do this?

Thanks in advance.
