if you are looking for a regex. that elas with only one line at a
time: <string1>(.*)<string2>
in Perl or python this should be enough, the result will be in some variables.
I prefer, awk, and in awk and variants you will have to use
match(function). Result will be first element in array.
eg (from "GAWK: Effective AWK Programming"):
$ echo foooobazbarrrrr |
> gawk ’{ match($0, /(fo+).+(bar*)/, arr)
> print arr[1], arr[2]
> print arr[1, "start"], arr[1, "length"]
> print arr[2, "start"], arr[2, "length"]
> }’
a foooo barrrrr
a 1 5
a 9 7
sed/grep, I don't know if such a thing is possible.
