我尝试使用正则表达式，

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

上面的表达式从第一个StatusMsg到Accepted进行选择。任何人都可以帮助构建正确的正则表达式吗？

你只需要对你的正则表达式做一点小改动就可以做到这一点。请注意，对于您的正则表达式，您还需要最后的m标志。

更新的正则表达式：

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

注意：要使用 rubular 进行测试，请将/开头和/m结尾的 去掉，然后将 放在m您输入正则表达式的右侧的小文本框中。这会将m标志设置为应用，这会导致.您的正则表达式匹配换行符（不是默认行为）。

唯一改变的是

StatusMsg:.*?

已经成为

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

这适用于负前瞻。这实际上是告诉您的正则表达式仅匹配您的正则表达式匹配的位置，但仅当匹配项不包含两个字符串时StatusMsg。

如果StatusMsg总是出现在行首且没有前面的空格，则可以通过以下方式使其更加具体：

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