Crash under input xml string which should catch as err

[yutongp]

Following code crashes:

var doc = new xmldom.DOMParser({
      errorHandler:function(key,msg){
      console.log(key, msg);
    }
}).parseFromString('<!', 'text/xml');

with err msg:

xmldom/sax.js:480
    var len = matchs.length;
                    ^
TypeError: Cannot read property 'length' of undefined

And here is another one:

var doc = new xmldom.DOMParser({
  errorHandler:function(key,msg){
    console.log(key, msg);
  }
}).parseFromString('</', 'text/xml');
