关于捕获的开始和结束的正则表达式新手问题

Question

我需要一些正则表达式的帮助.请参阅下面的示例.我正在捕获它之间包含的特定rid值

","children":[

并以此结束

 
}]}]}

如下所示.

我的问题是下面显示的块重复了几次,我希望所有rid ","children":[ to }]}]}只在每个块的开始之间.

我知道我可以用以下方法捕捉个人摆脱价值: rid":"([\w\d\-\."]+)

但我不知道如何指定捕获所有rid":"([\w\d\-\."]+)该开始之间存在","children":[以 }]}]}

例:

     ","children":[{"type":"stub","context":"","rid":"b1c4922237ce.ee6a3644443fe.10711226e93.d0af7aadbd0-4be3-4353ddd.8b47.f2f4aaf2474f","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.290c6e93.91c15f91-a1c-4c36.9939.4ab7b94a39ad","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.27c3ee93.22e90c22-7406-463a.8bff.f6ea88f6ffcc","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.6a182e93.5c0e7d5c-ff65-451d.afc0.cfc7fbcfc02d","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.6970ae93.8ea3978e-112b-4bbb.8405.d17071d105d2","metaclass":"ASAPModel.BarrierCategory"}]}]},

     ","children":[{"type":"stub","context":"","rid":"b1c4922237ce.ee6a3644443fe.10711226e93.d0af7aadbd0-4be3-4353ddd.8b47.f2f4aaf2474f","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.290c6e93.91c15f91-a1c-4c36.9939.4ab7b94a39ad","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.27c3ee93.22e90c22-7406-463a.8bff.f6ea88f6ffcc","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.6a182e93.5c0e7d5c-ff65-451d.afc0.cfc7fbcfc02d","metaclass":"ASAPModel.BarrierCategory"},
{"type":"stub","context":"","rid":"b1c497ce.ee6a64fe.6970ae93.8ea3978e-112b-4bbb.8405.d17071d105d2","metaclass":"ASAPModel.BarrierCategory"}]}]},

我的问题是我不明白如何指定启动非捕获组的起点和终点值以及如何识别这些捕获组中的一个或多个类似 []+

这看起来像JSON(尽管您的示例数据不完整无效).

如果是这样,那么CPAN的JSON模块可能是最好的前进方式:

use strict;
use warnings;
use JSON qw( from_json );

# my example data
my $data = q( [ 
    {"children":[ {"type":"stub","rid":"aa"}, {"type":"stub2","rid":"bb"} ] }, 
    {"children":[ {"type":"stub","rid":"cc"}, {"type":"stub2","rid":"dd"} ] } ]
);

my $json = from_json( $data );

for my $rec ( @$json ) {
    for my $child ( @{ $rec->{children} } ) {
        say "rid: ", $child->{rid};
    }
}

这打印:

rid: aa
rid: bb
rid: cc
rid: dd
