It depends on what the external Perl routine does.
In particular I want to use LWP::UserAgent to grab a web page, pipe
the output to Tom Christiansen's "striphtml" routine
(http://www.cpan.org/authors/Tom_Christiansen/scripts/striphtml.gz)
and then pipe that output back in for some subsequent processing.
The striphtml program only consists of a few substitutions, so you
need to assign the page that is to be processed to $_. This is one way
to make use of the program:
sub striphtml {
local $_ = shift;
do 'striphtml.pl';
$_
}
$page = striphtml($page);
