Regexp.match(string) will return you a MatchData object, which is not just the match: It can be accessed as an Array. So: sub[0] returns the entire matched string sub[1], sub[2], ... return the values of the matched back references (the ones between parentheses).
sub[1] is therefore the thing you want to use. No need to use to_s. On 22 sep, 14:20, jef <[EMAIL PROTECTED]> wrote: > hi > > /.*<coordinates>(.*)<\/coordinates>.*/ The reg exp you gave works > fine.
