Yet, won't yours -- id:\"[^ ]+\" -- match too much in this example: Bla, bla, see id:"some@thing"--"some famous quote" is bla. How about this one? id:\(\"?\)[^[:space:]"]+\1 Test: id:some@thing "something" id:"some@thing"--"something" id:"some@thing"--something id:some@thing "something else" id:"some@thing"--"something else" id:"some@thing"--something else id:some@thing id:"some@thing" Grüße, Thomas
