printing only the middle word between two patterns

How would I print the word "and" between the words "FOO" and BAR" using sed? My file has three words in it FOO and BAR. I only want the word "and".

Thanks every one.

Code:
sed -e's/\<FOO\>.*\<\(.*\)\>.*\<BAR\>/\1/'

Code:
 awk '{ print $2 }' <In File>

If your infile contains 3 coloumns, then it will print middile coloumn only.

Thanks Scrutinizer, that worked great.

How would I modify this to print an IP address?
(FOO 10.192.12.102 BAR)

I thought it would work for anything in between two words but I see it only works for text. I tried

sed -e's/\<FOO\>.*\<\([.0-9]*\).*/\1/'

but it does not produce and results.

Thanks

Try this:

Code:
sed -e's/\<FOO\>\W\+\<\(.*\)\>\W\+\<BAR\>/\1/'

Thanks Deepaks. That worked. What exactly is the command saying?

Since you asked..

s means search and replace, the forward slash starts the match.
- match FOO in word boundaries ( \< and \> ), followed by
- At least one character that is not alphanumeric or underscore ( \W\+ )
- Then look for any characters ( .* ) in word boundaries.
- Mark these characters by using \( and \) so that we can reproduce it later using \1
- Then this is followed by non alphanumeric or underscore characters, followed by
- BAR in word boundaries
- / marks the end of the match
- \1 reproduces the marked characters
- / marks the end of the search and replace
