我試圖與正則表達式，

(StatusMsg:.*?dId:\s*"Sa01".*?eventType: UPDATE_CMD.*?response\s*{[\s\n\w\.:]*dId:\s*"Sa01"[\s\n\w\.:]*status:\s*Accepted)

上述表達式從第一StatusMsg選擇直到接受。任何人都可以幫助構建正確的正則表達式嗎？

你只需要對你的正則表達式做一些小的改動就可以做到這一點。請注意，使用您的正則表達式，最後還需要標記m。

更新的正則表達式：

/(StatusMsg:(?!.*StatusMsg:).*?dId:\s*"Sa01".*?eventType: UPDATE_CMD.*?response\s*{[\s\n\w\.:]*dId:\s*"Sa01"[\s\n\w\.:]*status:\s*Accepted)/m

注：對於rubular測試，剝去/在開始和/m末，並把m的小文本框到一個地方的權利你正在輸入你的正則表達式。這將設置要應用的m標誌，這會在您的正則表達式中導致.匹配換行符（而不是默認行爲）。

所更改的唯一的事情還有就是

StatusMsg:.*?

已成爲

StatusMsg:(?!.*StatusMsg:).*?

這工作負向前看符號。這實際上是告訴你的正則表達式只匹配你的正則表達式匹配的地方，但只有當匹配不包含兩個字符串StatusMsg。

如果StatusMsg總是在沒有前面的空白行的開始，你可以把這個稍微做具體：

^StatusMsg:(?!.*^StatusMsg:).*?

謝謝你的解決方案。只有匹配的部分位於輸入的最後部分，您的解決方案纔有效。我修改了輸入，以便我的預期匹配不是最後一組消息。你能幫我選擇當前輸入的預期匹配嗎？ – MIZ

嗯。還沒有提出一個純粹的正則表達式解決方案;但是你可以通過'input_str.split（/^StatusMsg /）'讓自己更容易，然後遍歷數組中返回的對象，搜索你想要的模式。 – bdx

任何人都得到了這個問題的答案 – MIZ
