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 } } 要注意的是: xmlDoc.async = false; 写成这样 IE ， fireFox 都可以 xmlDoc.async = "false"; IE 可以 fireFox 会报错 --></p></div> 以上代码是讲解js、jq读取xml文件的方法，希望大家喜欢。
