Perl Array and Hash references Handling

my problem is that i'm getting no Output at the end of Script.. All the prints while parsing are ok, but arrays at end are empty.

What i'm doing wrong? Isnt this the way to handle the refs?

thx 4 response

    $content = $content->decoded_content;

    my @rows = split /\n/, $content;
    my $trigger = 0;

    while (defined($_ = shift @rows)) {

Sample Input:

    Kontext Auswertung fuer Ticket: #12345 (xxxxSomeTextxxx)

    HINWEIS: xxxxSomeTextxxx

    Branch: HEAD

    Sourcen (4):

    geaenderte Methoden (1):

    geaenderte Workflows (2):


It's quite hard to figure it out without any input data, because it means that we can't run a copy of the script on our own machines! It is generally pretty useful if your sample code is self-contained!

That said, I think your problem stems from doing this kind of thing:

my $branch_ref = $branches{$1};
%tmp_branch = %$branch_ref;

The second line does a shallow copy of the hash, so %tmp_branch is no longer the same hash as the one referenced by $branches{$1}. When you add data to the %tmp_branch hash, you are not adding data to the $branches{$1} hash.

@tmp_array suffers similarly.
