Question

我在解析以下config.yml文件时需要一些帮助：

yamlFile:    
    map:    
        "[abcd.txt]":    
            - name: John    
            - city: Omaha    
        "[efgh.txt]":    
            - name: Sandra    
            - city: Columbus    
        "[ijkl.txt]":    
            - name: Annie   
            - city: Chicago

我正在使用以下脚本进行解析。

my $config = LoadFile('config.yml');   
use Data::Dumper;    

for my $conf ( keys %$config ) {    
    print "$conf\n";   
    my $map = $config->{$conf};    
    for my $map1 ( keys %$map ) {    
        print "$map1\n";    
    }    
}

这将打印以下内容：

yamlFile    
map

由于$ map1的键不同，如何进一步获取每个元素的名称和城市？

以下是如何访问YAML配置文件中项目的示例：

use feature qw(say);
use strict;
use warnings;
use YAML qw(LoadFile);

my $config = LoadFile('config.yml');   
my $map_hash = $config->{yamlFile}{map};    
for my $conf ( keys %$map_hash ) {    
    say $conf;   
    my $elems = $map_hash->{$conf};
    for my $map1 ( @$elems ) {    
        for my $data ( keys %$map1 ) {
            say "$data:", $map1->{$data};
        }
    }    
}

输出：

[ijkl.txt]
name:Annie
city:Chicago
[abcd.txt]
name:John
city:Omaha
[efgh.txt]
name:Sandra
city:Columbus
