Regex将子句的键、运算符和值分组
从如下图所示的子句中获取一组键、运算符和值的最佳正则表达式是什么 到目前为止，我所做的并不准确，只能得到第一组：Regex将子句的键、运算符和值分组,regex,regex-group,Regex,Regex Group,从如下图所示的子句中获取一组键、运算符和值的最佳正则表达式是什么 到目前为止，我所做的并不准确，只能得到第一组：（^.*？（=|！=）+（[^.]*）） 使用 (\w+(?:\.\w+)*)\s*(!=|=)\s*(\w+) 看 解释 -------------------------------------------------------------------------------- ( group and capture to \1

显然你不知道从哪里开始你的正则表达式。有关正则表达式的详细信息，请查看和[Learning Regular Expressions}（）。不太清楚正则表达式应该遵循哪些规则。请尝试
