How to delete lines between 2 line patterns using regex?

Question

So I have a file like:

    FLAGSHARE
    xxxxxx
    xxxxx, 1 2015

    words....

    FLAGSHARE
    xxxxxx
    xxxxx, 2 2015

    words....

    FLAGSHARE
    xxxxxx
    xxxxx, 3 2015

    words....

etc.etc.

How would I be able to delete the three lines FLAGSHARE, xxxxxx, xxxxx, * 2015 (essentially remove FLAGSHARE, 2015 and lines between FLAGSHARE and 2015) using Notepad++?

You can use the following to match:

FLAGSHARE[\s\S]*?2015

And replace with '' (empty string)

With this pattern if FLAGSHARE is followed by for example 2013, it will remove all the lines until 2015 is found. regex101.com/r/rR1wP0/1

I had the same use case. I wanted to delete some code from a file which is generated dynamically.

You can also use:

FLAGSHARE[\S\s]*?\d{4}

DEMO

Which will also match any year

You could also use:

FLAGSHARE[\S\s]*?20\d{2}

For any year int he format: 20**

Or even:

FLAGSHARE[\S\s]*?\d\s*\d\n

Which will work in all situations
