Question

我有一个5MB的文本文件，我需要找到所有的电子邮件地址并删除其他所有内容。

文本文件包含以下代码段中的项目：

我能够研究如何使用正则表达式在Editplus中查找电子邮件地址。我只是无法找出find / replace命令来删除除电子邮件地址之外的所有内容，并确保电子邮件地址被一行分开。

下面放入Editplus find命令时，给我发电子邮件：

[a-zA-Z0-9\.\-_]+@[a-zA-Z0-9\.\-_]+\.[a-zA-Z0-9\.\-_]+

我很感谢帮助删除除电子邮件地址之外的所有内容。

Answer 1

描述

([a-zA-Z0-9\.\-_]+@[a-zA-Z0-9\.\-_]+\.[a-zA-Z0-9\.\-_]+)|.

替换为： $1

Regular expression visualization

我将表达式包装到( ..your expression.. )|.然后只需替换所有内容，如果要替换的子字符串是与您的表达式匹配的电子邮件地址，那么它将被捕获到$1并替换为返回字符串

Answer 2

这真的不复杂，特别是如果你打破了任务。

根据您的正则表达式，电子邮件地址必须有@标志。所以我使用这个正则表达式（启用多行/全局模式）使用全局替换：

^[^@]+$

结果是：

sales@trol.com
Joey.Boss@BCape.com

Joey.Boss@BCape.com

现在，您只需要用换行符替换多个空格，这可以通过此正则表达式完成：

\s+

对于您的数据，我建议您考虑使用一个或两个简单的正则表达式来保持可读性。像这样的正则表达式将为您提供迄今为止最佳的性能（other answer需要超过10,000步才能完成，与我的相比，只需要60或者1000％的速度给予或接受）。

Editplus - 查找电子邮件地址，删除其他所有内容
