我有一个字符串，我希望使用正则表达式将一些信息与字符串分开。

我知道的以下代码有两个问题：1）它无法捕获日期“20120623”，原因是我不太确定我理解（也许编译的正则表达式查询没有做我期望它做什么？），和2）我用来指定表达式如何结束的当前正则表达式不适用于字符串中的最后一个匹配项。

我可能会修改这个问题的标题，具体取决于问题/解决方案的最终结果。

当前代码：

尝试使用正则表达式：

(\d{8}\s)10\.3\s-84\.8\$(.*?)(?=\d{8}|$)

由于匹配重叠，您当前的正则表达式正在阻止连续匹配；我通过使用(?= ... )一个零宽度断言的积极前瞻来删除它。

此外，我逃脱了你的时期。如果打算成为文字点，则应将其转义。

看起来您的正则表达式不会匹配您的字符串。

您的正则表达式查找 8 位数字，然后是“10.3 -84.8$”，然后捕获所有内容，然后再捕获 8 位数字。但是，看起来您的字符串在其他任何地方都没有这 8 位数字。
