in reply to system & shell metacharacters

Are you sure you want to pass XML data on the command line? Why not have bar.pl read the XML data from stdin? Or, for that matter, why not just give bar.pl the name of the file and have it read the XML file itself?

    I'm with you. I'd use something like 
    open BAR, '|bar.pl' || die qq(Useful msg: $!);
print BAR $xmldata;

    and let bar.pl read from STDIN. No shell at all. OP might want a glance at perlipc.

      open BAR, '|bar.pl' || die qq(Useful msg: $!);

      ... is wrong, because it is interpreted as:

      open BAR, ('|bar.pl' || die qq(Useful msg: $!));

      ... so remember to use "or die" rather than "|| die".

    Do not pass large amounts of data on the command line. The system only provides a certain amount of memory for that data and you can not exceed that amount.
