Replace all non Alpha Numeric characters, New Lines, and multiple White Space with one Space

Question

I\'m looking for a neat RegEx solution to replace

• All non Alpha-Numeric Characters
• All NewLines
• All multiple instances of white space

Answer 1

Well I think you just need to add a quantifier to each pattern. Also the carriage-return thing is a little funny:

text.replace(/[^a-z0-9]+|\s+/gmi, " ");

edit The \s thing matches \r and \n too.
