python - 正则表达式 XML 选择提取元素

Question

我正在尝试从 BYPASS 0 0 0 开始进行正则表达式选择，直到并包括它显示的部分 WAK 0 0 这是我所拥有的 (?s)(?=BYPASS).*?(WAK....) 我认为我使用 python 的语法不正确，这也是我在 python 脚本中使用它的方式 re.split(r '(?s)(?=BYPASS).*?(WAK....)', r) 我相信这对我造成了问题 (?s) 结果是不正确的正则表达式选择。

Answer 1

Here是以下匹配正则表达式的示例:

BYPASS.*?(?:WAK \d \d)

这是在 Python 中实现正则表达式的方式:

import re
matches = re.findall(r'BYPASS.*?(?:WAK \d \d)', string, flags=re.S|re.M)

我必须使用 ?: 摆脱捕获组并将标志设置为参数以使其正常工作，但这应该是您所需要的。
