I don't know if you can do it with a single grepand a perl-like "look ahead" / "look behind" match. You can do it with two greps, though (or use perl or awk or similar):
Code:
grep -o "[>].*[<]" file | grep -o "[^<>]*"
word word word word.
word word word word word word .
word word word word word word word word .
word word word word word word word word word word word word word word word word word .
