Problem running Perl Script with huge data files

Hello Everyone,

I have a perl script that reads two types of data files (txt and XML). These data files are huge and large in number. I am using something like this :

Code:
foreach my $t  (@text)
{
    open TEXT, $t or die "Cannot open $t for reading: $!\n";
  
    while(my $line=<TEXT>){
       ....My code....
    }
}
close(TEXT);

foreach my $x  (@xml)
{
    open XML, $x or die "Cannot open $x for reading: $!\n";
  
    while(my $line=<XML>){
       ....My code....
    }
}

When I run it directly like following, it gives me "Out of memory" error:

Code:
Usage: perl runXML.pl

Can anyone suggest me as to how I can run this using "qsub" or something? I have these files in a directory structure like this:

Code:
/Data/2010_aaa/data.txt
/Data/2010_aaa/data.xml

/Data/2010_bbb/data.txt
/Data/2010_bbb/data.xml

/Data/2010_ccc/data.txt
/Data/2010_ccc/data.xml

/Data/2010_ddd/data.txt
/Data/2010_ddd/data.xml

And I need to run this script on all these files, as my data is scattered in these files.

Thanks!
