以下是两个示例:

这些具有以下要求:

• 值的开头不是逗号，冒号，右括号或空格.

否则，您必须对其进行改进.第二个甚至允许值以空格开头，但也可能会有其他副作用...

Otherwise you have to improve it. The second one even allows values to start with a whitespace, but may also have some other side-effects ...

示例1:

\"[A-Za-z0-9][^"]+\"\s*[^,:}\s]

示例2:

\"([A-Za-z0-9\s][^"]+\"\s*[^,:\]}\s]){2}
