NOTEPAD ++ REGEX-我无法获取两个字符串之间的内容，我无法获取

Question

I'm so close to understanding regex. I'm a bit stumped, I thought i understood lazy and greedy.

Here is my current regex: <g_n><!\\[CDATA\\[([^]]+)(?=]]><\\/g_n>)

My current regex makes:

<g_n><![CDATA[xxxxxxxxxx]]></g_n>

match to:

   <g_n><![CDATA[xxxxxxxxxx

But I want to make it match like this:

xxxxxxxxxx

Answer 1

You want

<g_n><!\[CDATA\[(.*?)]]></g_n>

then if you want to replace it use

\1 

in the replacement box

Your matching the whole string, the brackets around the .*? match all of that and put it in the \\1 variable

So the match will be all of the string with \\1 referring to what you want

To change the xxxxx

Regex :

(<g_n><![CDATA[)(?:.*?)(]]></g_n>) 

Replacement

\1WHAT YOU WANT TO CHANGE TO\2

Answer 2

It looks like you need to add escape slashes to the two closing square brackets, as they are literals from the string you're parsing.

<g_n><!\[CDATA\[.*+?\]\]><\/g_n>
                    ^ ^ 

Any square brackets not being escaped by backslashes will be treated as regex operational brackets, which in this case won't catch the input string.

EDIT, I think the +? is redundant.

\[.*\]\]> ...

should suffice, since .* means any character, any amount of times.

Answer 3

Tested with notepad++ 6.3.2:

find: (<g_n><!\[CDATA\[)([^]]+)(?=]]></g_n>)
replace: $1WhatYouWant

You can replace + by * in the pattern to match void CDATA:

<g_n><![CDATA[]]></g_n>
