如何解决如何使用python脚本从文本文件中选择大括号内的有用信息？
我有一个巨大的文本文件，其中包含以这种格式存储的信息。

我想使用 py 脚本遍历此文件并按以下格式构建 dict（或任何其他数据结构）。
例如。
someOtherMessage{
class = "someClass";
sampleMessage{
someValue{
someText{
someParam = "value";
someSymbol = "another_symbol";
}; //someText
}; //someValue
}; //sampleMessage
}; //someOtherMessage
someOtherMessage2{
class = "someClass2";
sampleMessage2{
someValue2{
someText2{
someParam = "value2";
someSymbol = "another_symbol2";
}; //someText2
}; //someValue2
}; //sampleMessage2
}; //someOtherMessage2
我使用了以下正则表达式，但它选择了第一个和最后一个大括号之间的所有内容，如何让它分别选择所需的？
解决方法
这是您的问题的可能解决方案之一。 我假设您了解贪婪和惰性量词。如果没有，这里是一个链接：Greedy vs. Reluctant vs. Possessive Qualifiers
(?s)\{(.*?)\};.*?(\n\n|$)
错误
在原始的正则表达式 (?s){(.*)} 中，您使用了贪婪量词，它匹配太多，因此导致匹配了我们不想要的东西。
如果你用一个惰性量词替换它，(?s){(.*?)}，它匹配的太少又会导致匹配不想要的东西。
更正
为了指定更正结尾 }，我们必须找到一些东西来锚定我们的匹配。这就是要获取的数据之间的新行发挥作用的地方。
}; //someOtherMessage
someOtherMessage2{
在该 \n 注释之后有一个 someOtherMessage，然后在该新行中有另一个 \n。所以我们添加
`(?s)\{(.*?)\};.*?\n\n`
这只是意味着{...something here...}...something here...\n\n。
这个正则表达式仍然不会是结束数据，因为它最后没有任何 \n。
}; //someOtherMessage2'
}
为了匹配它，我们通过删除 $ 修饰符来设置 m 以匹配文件结尾。这会将我们的正则表达式更改为：
(?s)\{(.*?)\};.*?(\n\n|$)
我希望我能帮助你解决你的问题。请注意，这是您问题的可能解决方案之一。 还有另一种方法可以找到匹配的嵌套括号，它也可以在 SO 上使用。但是，它可能有点复杂。这是一个这样的链接：Can regular expressions be used to match nested patterns?
