我正在寻找正确的正则表达式来匹配包含“ - >”的句子中的所有空格。
.*->.*\r?
用于选择所有正确的句子,但我很难用/ s
连接它示例文本:我尝试重新格式化字幕文本。我需要从时间码中取出所有空格:
7
00: 00: 20,509 -> 00: 00: 25,059
on the data before and does not shy in front of radical solutions such as post privacy back.
8
00: 00: 25,159 -> 00: 00: 27,896
On his blog writes sower already since 2011
9
00: 00: 27,996 -> 00: 00: 31,784
on the impact of technology on society, politics and economy.
预期结果将是:
7
00:00:20,509->00:00:25,059
on the data before and does not shy in front of radical solutions such as post privacy back.
非常感谢!

根据你的样本,正则表达式中的一些解决方案比^^!
(冒号和空格)更复杂:
:
仅在前面有((?:(?<\d:)|(?<=->)) | (?=->))
或[0-9]:
或紧跟->
的空格
A shorter one(但更多的错误证明):
->
与上面相同的想法,在前瞻中交替进行。
The most exact one与您的格式完全匹配,但需要((?:(?<=:|>)) | (?=->))
而不是替换
\1\2\3-->\4\5\6
