Remove BBCode with Regex in Javascript

Question

I am trying to remove BBCode with attributes and content between those tags. I'm using this regular expression that I got here from here. I also tried other regex I found on stackoverflow but they didn't work for me, just the one I copy here is the closest.

([[\/\!]*?[^\[\]]*?])

I added a . before *?]) and it maches the text between the tags but also matches pokemon and I don't want that.

**Regex**: ([[\/\!]*?[^\[\]].*?])

**Text**: I'm a pokemon master and I like
[TAG] this [/TAG] pokemon [TAG] and this [/TAG] text...

I use this web to test regex http://regexpal.com/

Can anyone help me?

Thanks in advance.

str = str.replace(/\[(\w+)[^\]]*](.*?)\[\/\1]/g, '');

jsFiddle.

This is what you want:

.replace(/\[(\w+)[^\]]*](.*?)\[\/\1]/g, '$2');

JavaScript demo

Basically you catch the value between tags and then replace the whole string with that value.

Using a regex to do this isn't a very clean way of doing it though...

Sorry Alex but you didn;t read it seems.

It's almost the same... hehe. I'm getting a feed from a forum and I'm using javascript only to develop something. THanks.

What is [^w]? How would that allow for arbitrary attributes?

This should do:

\[(\w+).*?\].*?\[/\1\]

This will look for a closing tag matching the opening tag - and also accept attributes on the opening tag. The JavaScript code should then be:

str = str.replace(/\[(\w+).*?\].*?\[\/\1\]/, "");
