Thanks for the replies!
I've just found a solution by accident:
  /regexp/e cat file.txt

Documentation is not very clear here: "If a parameter is specified,
instead, the e command interprets it as a command and sends its output
to the output stream (like r does)."
(http://www.gnu.org/software/sed/manual/sed.html#Extended-Commands)
There's a difference, as r sends the output at the end of a cycle,
while e sends it immediately.
