这是我的期望：

***NEW ISSUE SUPPORTED THROUGH UNIVERSALITY   vs 104-13 on AY 3s JAN   
10+BB {MYXV ABC 4116    SM  MYXV YA 102-15 <DO>} | 2010/11 4.0s             4.0s
6+ BB {MYXV ABC 4132    NS  MYXV YT 102-22 <DO>} | 2010 4.5s                4.5s

10+BB  {NXTW VXA 12-47  SP  MYXV YA 106-20 <DO>} | 22 wala 4.0s             4.0s

如果***线条也可以消除就好了。

这就是我到目前为止所得到的(?P<header>[\S+\s]+At:.*)\n+(?P<body>[\S+\s]([\d\.\d]+[a-z]?$))。这似乎做得不好，因为它在最后 4.0 秒后抓住了虚线并卡在了非 ascii 字符©上。谢谢！

PS：我认为最好的方法是用组切断电子邮件的标题和尾部。所以剩下的就是身体了。因为标题和尾部始终保持不变，但正文在不同的电子邮件中会发生变化。解决方案不需要特定于电子邮件。

看看这是否适合您，您想要的行以数字开头，后跟加号：

^[0-9]*\+.*$

这将匹配预期的输出：

\*{3}[^\*]*(?:(?=\*{3})|(?=^-*$))
  1. ^ 匹配字符串的开头。
  2. [0-9]匹配 0-9 范围内的任何单个字符。
  3. *匹配 0 个或多个前面的令牌。这是一个贪心匹配，在满足下一个标记之前会匹配尽可能多的字符。
  4. \+匹配一个 + 字符。
  5. . 匹配任何字符。
  6. $匹配字符串的结尾。
