Or somewhat safer (and way more complicated):

   function(aTag, aTagName, aAttributes) {
      return aTagName.toLowerCase() +
            function(aAttribute, aName, aValue) {
               return aName.toLowerCase() + aValue;
// just don't tell me that a RegExp is no replacement for a parser ;)

If you prefer Neil's version, I'd at least replace \b\w+= with \s\w+= in
order to not convert URL arguments (i.e. HREF="?OrderNo=42" shouldn't
become href=""?orderno=42").
