我现在想用js代码 读取 最大的 serial节点也就是 最后读取的应该是 第四集我的js不好...请大家帮忙啊 ...

解决方案 »

  1.   

    var xmlDoc = new ActiveXObject("Microsoft.XMLDOM"); //创建XmlDom对象xmlDoc.async=true; //使用异步加载
    xmlDoc.load("test.xml");
    var cartoons = xmlDoc.documentElement.selectNodes("cartoon");//获取cartoon节点的数组alert(cartoons[cartoons.length-1].childNodes[0].text);
