我正在寻找解析 YAML 文档的帮助。具体来说，我不确定主机是否打印/访问“卷”元素。任何帮助将不胜感激。提前致谢！

代码：

#!/usr/bin/perl

use YAML::Tiny;


# Open the config
$yaml = YAML::Tiny->read( 'file.yml' );

# Reading properties
my $root = $yaml->[0]->{rootproperty};
my $one  = $yaml->[0]->{physical_interfaces}->{e0a};
my $Foo  = $yaml->[0]->{physical_interfaces}->{e0b};
print "$root\n";
print "$one\n";
print "$volume1\n";

我的 yaml 文件如下所示：file.yaml
