Remove every white space between tags using JavaScript

Question

I\'m trying to remove white space between tags so that childNodes only contain those tags nodes not the white space nodes too. Here\'s my code :

Answer 1

only spaces:

parentHTML = parentHTML.replace( new RegExp( "\>[ ]+\<" , "g" ) , "><" ); 

new line, tabs and spaces:

parentHTML = parentHTML.replace( new RegExp( "\>[\s]+\<" , "g" ) , "><" );
