如何使用正则表达式批量删除

Question

I have a lot of incoming emails and I want to save all in notepad

    checkzone@anagram
    12:56 AM (7 hours ago)

    to me 
    Live => example1@gmail.com | example1

    checkzone@anagram
    6:31 AM (2 hours ago)

    to me 
    Live => example2@gmail.com | example2

    checkzone@anagram
    6:31 AM (1 hours ago)

    to me 
    Live => example3@gmail.com | example3

so it becomes like this

Live => example1@gmail.com | example1
Live => example2@gmail.com | example2
Live => example3@gmail.com | example3

how to delete all

checkzone@anagram
6:31 AM (1 hours ago)

Answer 1

You can use a regex like this:

[\s\S]*?(Live.*$)

With the replacement string:

$1\n
