</serviceItem>
<service>

$.get("service.xml",function(xml){
len=$(xml).find("serviceItem").each(function(){
var serviceItem=$(this);
var url=serviceItem.find("url").text();//读取子节点的值
var name=serviceItem.find("name").text();
var type=serviceItem.attr("type");
alert(url+"--"+name+"--"+type);

});

});
