Thanks a lot for your help! Much appreciated.

However, now the script is not working, it exits with an error message: "Not a HASH reference at blastHit.pl line 102." It points to this line:

push @{$ret},join '|',

Something seems to be wrong with @{$ret}; I am educating myself on how Perl handles arrays, hashes, references and such, but in the meanwhile I'd be grateful if you would share your thoughts on this. Why it is not working now when previously it worked with the single XML field?

Thanks a lot again!
