私は次の文字列があります。検索条件が指定された文字列を取得します。ブラケット、引用、より

NoticeText: 
    NoticeType [str] = USER_TYPING_ON 
    Text [str] = "user is typing" 
    EventInfo: 
     PartyId [int] = 2 
     EventType [str] = MESSAGE 
     UserNickname [str] = "Michael" 
     EventId [int] = 4 
     Text [str] = "Hey, how are you?" 
     MsgCheck [str] = NONE 
     TimeOffset [int] = 23 
     UserType [str] = AGENT 
NoticeText: 
    NoticeType [str] = USER_TYPING_ON 
    EventInfo: 
    PartyId [int] = 1 
     EventType [str] = MESSAGE 
     UserNickname [str] = "Bob Smith" 
     EventId [int] = 6 
     Text [str] = "I'm good, how are you?" 
     MsgCheck [str] = NONE 
     TimeOffset [int] = 28 
     UserType [str] = CLIENT 
     MessageType [str] = "text"

を、私は、文取得できるようにする必要があり、「私はいいんだが、お元気ですか？」。私は完全に困惑しています。

"Text [str] ="の後にフレーズを検索しようとしましたが、必要なものが返されました。しかし、 "Text [str] ="の後に他の文もすべて戻します。

PartyId [int]フィールドには、あなたを助けるヒントが1つあります。 1はクライアントに対応します。それは私が必要とする人のメッセージです。

私はちょうどその方法でそれを絞り込む方法がわかりません。

助けてください！

これらのブロックのリストが長い場合は、同じ表現のこの単純化されたバージョンですべてを解析することができます。私はグローバルフラグと複数行フラグ

例を使用しています。このバージョンでは

`^NoticeText:(?:(?!\nNoticeText:)[\s\S])\n\s+Text\s\[str\]\s=\s"([^"])"(?:(?!\nNoticeText:)[\s\S])`
は

キャプチャグループ0上記から同じサンプルテキスト付き

は、単一の取得しますNoticeTextであり、キャプチャ・グループ1はブロック内の最後のText [str]値のみを取得します

サンプル

MATCH 1 
Capture Group 1. [246-263] `Hey, how are you?` 

MATCH 2 
Capture Group 1. [566-588] `I'm good, how are you?`
