DOM 解析中的浏览器差异所有现代浏览器都支持 W3C DOM 规范。不过,浏览器之间是有差异的。
重要的区别有两点:</p><p>1、加载 XML 的方式 
 //IE浏览器
   var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
 //firefox 其他浏览器
  var xmlDoc = document.implementation.createDocument("","",null);
2、处理空白和换行的方式 
 Firefox,以及其他一些浏览器,会把空的空白或换行作为文本节点来处理,而 Internet Explorer 不会这样。
 思考: 那么怎么解决这种差异呢,下面是一种方法:
  for(var i=0;i<provinces.length;i++){ //在输出所有的子节点的时候
    if(provinces[i].nodeType==1){//在这里判断该节点是否是元素节点
     }
