Well, it can be line-oriented. It just depends on the regexp pattern and flags specified, i.e. `/^somePattern/someFormatter/` vs `/^somePattern/someFormatter/ms` (`m` flag to enable multi-line mode, `s` to let `.` match `\n`). It has support for multi-line matches, as well as matching per-line. Maybe I'm just misunderstanding you.

  By mentioning sed and line-oriented, I means you don't have to read all content of stdin (i.e. full buffering) before matching.

    Okay yes, you're correct; xo does not buffer stdin, because the regular expression pattern may span the entire contents.
