如何从ruby上的以下正则表达式中删除引用？-HowdoIremovethequotefromthefollowingregexponruby?

The problem is that (?) is .*, which will eat anything, including double quotes. An easy way to fix that would be to change it to .*?. (That's a reluctant matcher; it matches as few characters as possible, rather than as many as possible.)

问题是(? )是。*,它会吃任何东西,包括双引号。解决这个问题的简单方法是将其更改为。*? (这是一个不情愿的匹配器;它匹配尽可能少的字符,而不是尽可能多的字符。)

Another way to do it would be to use [^"]* rather than .*.

另一种方法是使用[^“] *而不是。*。

There is an important lesson to be learned about regexps here: whenever you write a regexp, don't just think about what you want to match; think about what you don't want to match. A very common source of errors with regexps is matching too much.

这里有关于regexp的重要教训:每当你写一个正则表达式时,不要只考虑你想要匹配的东西;想想你不想匹配的东西。 regexp的一个非常常见的错误来源是匹配太多。

You probably want to disallow quotation marks in the name. This will fix your example:

您可能希望禁用名称中的引号。这将修复您的示例:

/["]*(?[^"]*)[\"]*?\s*[<(](?\w.*)[>)]/.match("\"The Boss\" ")

If you want to support backslash escaping, you'll need something more sophisticated, though.

如果你想支持反斜杠转义,你需要更复杂的东西。
