Sorry, sorry, I am just not getting it. Sigh.
Anyway, I (of course) neglected to fully describe the XML hierarchy. It is not simply OneUploadedFile:ChecksumResult
It is DepositoryProcessingRecord:MultiFileDoc:OneUploadedFile:ChecksumResult
So, in trying to extrapolate, I am getting Not an ARRAY reference at ./parseXML.pl line 46. Line 46 is:
my $checkSumResult = $xmlRef->{DepositoryProcessingRecord}->{MultiFileDoc}->{OneUploadedFile}->[0]->{'FinalDocStoragePath'};
I apologize; I just can't get my head around this.
