Looks like you have a program that is not working correctly.
Do you have any experience with Perl?

I copied this from the Linux article (adding the use lib path) and it seems to work ok.
Is this the script you are using?

eley@bumby:~$ cat x.pl
#!/usr/bin/perl -w
use lib '/home/moseley/123/swish-e-2.4.1/prog-bin';
use pdf2xml;


my @files =
    `find /usr/share/cups/doc-root -name 'i*.pdf' -print`;
for (@files) {
    chomp();
    my $xml_record_ref = pdf2xml($_);
    # this is one XML file with a SWISH-E header
    print $$xml_record_ref;
}

moseley@bumby:~$ perl x.pl | swish-e -S prog -i stdin  -T properties
