Hi all. I have been searching for this kind of match for quite some time. Also trying several things, but without any result. I am trying to capture content between 2 words. In this case the 2 words are statis and the content between them is dynamic. For example: My house number is 21 you know. So i would like to capture the 21 in this case between "is" and "you". Anybody who has any suggestion in this? Cause i just can't seem to figure this out for some reason.
