Question

我有这样的正则表达式：

(.*?)("DisplayName":.*?)(,)(.*?"Groups":?)?(\[.*?\])?(,)(.*?"Phones":)?(\[.*?\])?(.*?\},)?

我想用它来处理这样的字符串：

{“Affinity”：20，“DisplayName”：“Moe Larry”，“电子邮件”：[{“Address”：“moelarry@gmail.com”，“Primary”：true，“Type”：{“Id “：”HOME“}}]，”FullName“：{”FamilyName“：”Larry“，”GivenName“：”Moe“，”Unstructured“：”Moe Larry“}，”Groups“：[{”id“： “^ Mine”}}，“Id”：“1234567890”，“MailsSent”：0，“Name”：“Moe Larry”，“Phones”：[{“Number”：“555-999-6661”，“Type “：{” ID “：” 移动设备 “}}]，” ProfileLink “：” “}，{” 亲和力 “：20，” 显示名称 “：” stoogesarefunny”， “电子邮件”：[{ “地址”： “stoogesarefunny” ， “主”：真}]， “EvergreenPhoto”： “/照片/私人/ adflk; jsd394u75430o8752380974321jtkasdljf8937489213749832654”， “ID”： “834754hthbf83744823f”， “MailsSent”：0}，{ “亲和力”：20， “显示名称”： “stoogesarefunny@gmail.com”， “电子邮件”：[{ “地址”： “stoogesarefunny@gmail.com”， “主”：真正}]， “EvergreenPhoto”： “/照片/私营/ asdfAJDKLJSFIOEJHLTHSJKLDF234987s897KJHSDFKJHDF89273473ASLKJDLSKJIFEIH”， “ID” ： “834754hthbf83744823f”， “MailsSent”：0 “ProfileLink”： “https://profiles.google.com/stoogesarefunny”}，{ “亲和力”：20， “显示名称”： “Shemp”， “全名”：{ “给定名称”：“Shemp “ ”非结构化“： ”Shemp“}， ”组“：[{” 我d “：” ^矿 “}]，” ID “：” 1234567890" ， “MailsSent”：0， “名称”： “Shemp”， “电话”：[{ “号码”： “+ 15553085671”， “类型” ：{ “ID”： “OTHER”}}]}，{ “亲和力”：20， “显示名称”： “ClownFace”， “全名”：{ “给定名称”： “ClownFace”， “非结构化”： “ClownFace”} ， “组”：[{ “ID”： “^矿”}]， “ID”： “1234567890”， “MailsSent”：0， “名”： “ClownFace”， “手机”：[{ “数”： “15556064040”， “类型”：{ “ID”： “OTHER”}}]}，

我知道这真的很难看。我希望我能找到一个xml feed，但现在不是一个选项。

我关心的只是DisplayName，群组和电话。我需要提取并将它们保存在一个数组数组中。群组和电话的捕获组必须是可选的，因为并非所有联系人都拥有它们。但是，我的正则表达式给了我：

Result 1

1. {"Affinity":20,
2. "DisplayName":"Moe Larry"
3. ,
4. "Emails":[{"Address":"moelarry@gmail.com","Primary":true,"Type":{"Id":"HOME"}}],"FullName":{"FamilyName":"Larry","GivenName":"Moe","Unstructured":"Moe Larry"},"Groups":
5. [{"id":"^Mine"}]
6. ,
7. "Id":"1234567890","MailsSent":0,"Name":"Moe Larry","Phones":
8. [{"Number":"555-999-6661","Type":{"Id":"MOBILE"}}]
9. ,"ProfileLink":""},

Result 2

1. {"Affinity":20,
2. "DisplayName":"stoogesarefunny"
3. ,
4. "Emails":[{"Address":"stoogesarefunny","Primary":true}],"EvergreenPhoto":"/photos/private/adflk;jsd394u75430o8752380974321jtkasdljf8937489213749832654","Id":"834754hthbf83744823f","MailsSent":0},{"Affinity":20,"DisplayName":"stoogesarefunny@gmail.com","Emails":[{"Address":"stoogesarefunny@gmail.com","Primary":true}],"EvergreenPhoto":"/photos/private/asdfAJDKLJSFIOEJHLTHSJKLDF234987s897KJHSDFKJHDF89273473ASLKJDLSKJIFEIH","Id":"834754hthbf83744823f","MailsSent":0,"ProfileLink":"https://profiles.google.com/stoogesarefunny"},{"Affinity":20,"DisplayName":"Shemp","FullName":{"GivenName":"Shemp","Unstructured":"Shemp"},"Groups":
5. [{"id":"^Mine"}]
6. ,
7. "Id":"1234567890","MailsSent":0,"Name":"Shemp","Phones":
8. [{"Number":"+15553085671","Type":{"Id":"OTHER"}}]
9. },

Result 3

1. {"Affinity":20,
2. "DisplayName":"ClownFace"
3. ,
4. "FullName":{"GivenName":"ClownFace","Unstructured":"ClownFace"},"Groups":
5. [{"id":"^Mine"}]
6. ,
7. "Id":"1234567890","MailsSent":0,"Name":"ClownFace","Phones":
8. [{"Number":"+15556064040","Type":{"Id":"OTHER"}}]
9. },

显然，所有Shemp的联系人数据都被归入stoogesarefunny@gmail.com的数据，因为我的正则表达式继续扼杀，直到它到达Shemps Group而不是在他的显示名称之前停止并重新开始。帮助

P.S。：不，我不打算保存所有这些组，最终，我只能这样研究发生了什么。

您的输入看起来像JSON，已经有Ruby的解析器：

gem install json

然后在红宝石中：

data = JSON.parse(string)

然后，您可以直接访问data作为哈希对象，例如：

data = '
  {"Affinity":20,
    "DisplayName":"Moe Larry",
    "Emails":[{"Address":"moelarry@gmail.com","Primary":true,"Type":{"Id":"HOME"}}],
    "FullName":{"FamilyName":"Larry","GivenName":"Moe","Unstructured":"Moe Larry"},
    "Groups":[{"id":"^Mine"}],
    "Id":"1234567890",
    "MailsSent":0,
    "Name":"Moe Larry",
    "Phones":[{"Number":"555-999-6661","Type":{"Id":"MOBILE"}}],
    "ProfileLink":""
  }
'

require 'json'
user = JSON.parse(data)
user.class                    # => Hash
user.keys                     # => ["Affinity", "DisplayName", "Emails", "FullName", "Groups", "Id", "MailsSent", "Name", "Phones", "ProfileLink"]
user['Affinity']              # => 20
user['DisplayName']           # => "Moe Larry"
user['Emails']                # => [{"Address"=>"moelarry@gmail.com", "Primary"=>true, "Type"=>{"Id"=>"HOME"}}]
user['Emails'].class          # => Array
user['Emails'][0]             # => {"Address"=>"moelarry@gmail.com", "Primary"=>true, "Type"=>{"Id"=>"HOME"}}
user['Emails'][0]['Address']  # => "moelarry@gmail.com"

如何使用Ruby的'scan'方法创建捕获组可选？
