in reply to Reading from a filehandle written to by a subroutine?

If your on 5.8.x, then you should be able to use a "memory file". See perlfunc:open/perlopentut. 

open my $memFH, '+>', \my $buffer;
$object->cat( $memFH, $target );
while( <$fh> ) {
    ## do something with it
}

# Or

$buffer =~ s[...][...]mg; #etc

    Thanks for the pointers. A bit of background, since I wasn't terribly clear:

    I'm trying to get info out of a Subversion repository, using the Subversion perl bindings. One of those modules has a method (cat) where you specify the a target (including a revision number), and it writes that version of the file to a filehandle you give it. So, there's no file for me to open, but I need to be able to read from the resulting filehandle to get back the file from the repository.

    The Memory file seems like a promising tack to take, I'll try that.

    Thanks.
