POSIX regexp for finding everything between wordX and wordY

I have string as:

FOO /some/%string-in.here BAR

I would like to get everything between FOO and BAR but NOT including FOO[:space:] and NOT including [:space:]BAR

Any ideas it will be appreciate it.

To get everything between FOO and BAR, except any spaces after FOO or before BAR, use this regex for POSIX ERE:

FOO[[:space:]]*(.*)[[:space:]]*BAR

or for POSIX BRE:

FOO[[:space:]]*\(.*\)[[:space:]]*BAR

Because POSIX only supports greedy quantifiers, this regex captures everything between FOO and the last occurrence of BAR, in case there is more than one BAR.

Can't you just use a capturing group?

/FOO (.+?) BAR/
