我生成了一个看起来像这样的哈希。 （使用翻斗车打印）

看过How to iterate through Hash (of Hashes) in Perl?并且无法让它为我工作。
需要遍历所有看起来像'sufia：s4655g60k'的键，然后对于每个键，我需要提取'curVer'并根据'curVer'的数量我需要循环'version.0 '获取键的相应值。
如何遍历此哈希并读取/更新现有键/值？
答案 0 :(得分：1)
for my $key (keys(%$VAR1)) {
my $rec = $VAR1->{$key};
my $cur_ver = $rec->{curVer};
my $subrec = $rec->{"version.$cur_ver"};
my $checksum_new = $subrec->{'checksum.new'};
my $checksum_old = $subrec->{'checksum.old'};
my $name = $subrec->{name};
my $path = $subrec->{path};
...
}
