错误集：js解析jQuery.post返回的xml之Could not find action or result

js里用jQuery.post去后台查询数据，返回的是xml格式的数据流。

js代码：

var params = "";
params = encodeURI(params);
var url = "frame.query.action";
jQuery.post(url, params, function(xmlHttp){

var items = xmlHttp.getElementsByTagName("jg");
for (var i = 0; i < items.length; i++) {
var x=items[i].childNodes;
var id=x[0].innerHTML;
var name=x[1].innerHTML;
var img=x[2].innerHTML;
if(i==0){
var text1=" <a href='common.jsp'><li style='margin: 0;'><img src='image/tab/"+img+"'><span>"+name+"</span></li>";
$(text1).appendTo($("#ul"));
}else if(i<6){
var text3=" <a href='common.jsp'><li><img src='image/tab/"+img+"'><span>"+name+"</span></li>";
$(text3).appendTo($("#ul"));
}else if(i==6){
var text2=" <a href='common.jsp'><li class='li-first'><img class='img7' src='image/tab/"+img+"'><span>"+name+"</span></li>";
$(text2).appendTo($("#ul"));
}else if(i>6){
var text4=" <a href='common.jsp'><li class='li'><img class='img7' src='image/tab/"+img+"'><span>"+name+"</span></li>";
$(text4).appendTo($("#ul"));
}

}

}, "xml");

用innerHTML获取标签里的值。在搜狗和火狐都是可以完美运行。可是如果换成IE的话就会报下面的错误。

错误信息：

解决的办法是把

var id=x[0].innerHTML;
var name=x[1].innerHTML;
var img=x[2].innerHTML;

替换成：

var id=x[0].firstChild.data;
 var name=x[1].firstChild.data;
var img=x[2].firstChild.data;
用这种方式获取标签里的值。我的判断是IE下用innerHTML取值是取不到。
