As others said, better use a real XML module!

Regarding 5 GB strings, I wouldn't be surprised if it couldn't be sufficiently held in memory and Perl's attempts to outsource leads to problems.

    I am running perl 5.16.2 64bit on a 16GB I7 machine and have given it a cursory test to the 16GB max and have found no other problems

    It could be the regex engine in x64 perl still has a 4GB limit?? substring() works out to 16GB $bigstring
