Notepad ++（Perl）正则表达式匹配多行模式

Question

I want to remove a div from a couple hundred html files

<div id="mydiv">
    blahblah blah
    more blah blah
    more html
    <some javascript here too>
</div>

I thought that this would do the job but it doesn't

<div(.*)</div>

Does anyone know which is the proper regex for this?

Answer 1

Regex

<div[^>]+>(.*?)</div>

Don't forget to check the option . matches newline . matches newline like in the image below :

Alternatively, you can use this regex also: <div[^>]+>([\\s\\S]*?)</div> with or without the checkbox checked.

Discussion

Since * metacharacter is greedy, you need to tell him to take as few as possible characters (use of ? ).

Check that the divs you want to remove DO NOT contain nested div. In that case, the regex at the start of my answer won't help you.

If you face this case, I'd suggest you using an html parser.
