Removing words using RegExp

I have a string with tags. "<blue>Hello, <red>world</red>!</blue>". And I have to get this string without tags using RegExp. I wrote this code, but I think that it can be easier. str.split('<red>').join('').split('</red>').join('').split('</blue>').join('').split('<blue>').join('');
Please, help me!

Solution

  • Use .replace(/<\/?(red|blue)>/g, ""):

    console.log( "<blue>Hello, <red>world</red>!</blue>".replace(/<\/?(red|blue)>/g, "") )

    If you want to match also case insensitive versions of the tags, you just need to insert i after /g. This will not work with attributes or spaces before or after the tag name. If you need it, comment on this answer and I will edit it.
