This is only barely tested, and should probably be expanded upon.

Regular expressions can use function replacement in order to do more complicated replacements. If we utilize that functionality we can come up with something like:

var tag = '<DIV STYLE="WOA"></DIV>';
tag.replace(/<(\/?\w+)/g, function(r) {
   return r.toLowerCase();
});

You'll need to make use of toLowerCase(), in conjunction with Regular Expressions.

Try this (from here):

s = s.replace(/< *\/?(\w+)/g,function(w){return w.toLowerCase()});

Where s is the innerHTML of the element containing tags you want to replace with their lowercase equivalents.

Try this:

str = str.replace(/<\s*\/?\w+/g, function($0) { return $0.toLowerCase(); });

try this : </?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>
