Ich habe die folgende Zeichenfolge: „Ich bin gut, wie du bist“Abrufen der angegebenen Suchkriterien. Klammern, Angebote und mehr

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"

Ich muss in der Lage, den Satz zu holen. Ich bin völlig ratlos.

Ich habe versucht, Sätze nach "Text [str] =" abrufen, das gibt zurück, was ich brauche. Aber es gibt auch alle anderen Sätze nach "Text [str] =" zurück.

Ein Tipp, der Ihnen helfen könnte, ist das PartyId [int], Feld. 1 entspricht dem Client. Welches ist die Botschaft der Person, die ich brauche?

Ich weiß nur nicht, wie man es dadurch eingrenzen kann.

Bitte helfen!

Alternativ

Wenn Sie eine lange Liste dieser NoticeText Blöcke hätten, könnten Sie sie alle mit dieser vereinfachten Version des gleichen Ausdrucks analysieren.

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

Regular expression visualization

Mit dieser Version ich die globalen Flag bin mit und dem Multiline-Flag

Beispiel

Mit dem gleichen Beispieltext von oben Capture-Gruppe 0 wird die Single NoticeText, und Erfassungsgruppe 1 erhält nur den letzten Text [str] Wert im Block
