杭州住房补贴政策2017:关于flash和XML 图片切换的这段代码怎么用？？

下面这个是我在网上找到的，但是没说怎么用
请问在哪里改图片路径？

简单点，就使用xml+flash,可以直接修改xml

第一帧： myid_num = new Array();
mytitle_num = new Array();
total = new Array();
System.useCodepage = true;
var myxml = new XML();
myxml.ignoreWhite = true;
myxml.load("date.xml");
myxml.onLoad = function(success) {
if (success) {
loader._visible = false;
parseXML();
} else {
trace("XML加载失败！");
}
};
parseXML = function () {
total = myxml.firstChild.childNodes[0].childNodes;
for (i=0; i<total.length; i++) {
myid_num[i] = total[i].attributes.myid;
mytitle_num[i] = total[i].attributes.mytitle;
}
shownews();
};
shownews = function () {
for (i=0; i<4; i++) {
duplicateMovieClip(this.news, "news"+i, i);
this["news"+i]._x = 13.5;
this["news"+i]._y += 5+i*23;
id1 = myid_num[i];
title1 = mytitle_num[i];
if (title1.length>=9) {
title1 = title1.substring(0, 9)+"...";
}
// id2 = "0"+id1+".";
id2 = "※ ";
title2 = id2+title1;
this["news"+i].txt = title2;
this["news"+i].onRelease = function() {
url1 = "http://football.ppn.cn/tnew.asp?id=";
id3 = this._name.slice(4);
id4 = myid_num[id3];
url2 = url1+id4;
trace(url2);
getURL("javascript :MM_openBrWindow("+"'"+url2+"'"+",'_b','resizable=no,scrollbars=yes,width=600')");
};
}
};

取名为"date.xml"的文件：
<?xml version='1.0' encoding='UTF-8'?>
<data>
<newsid>
<project myid="1" mytitle="新闻1" />
<project myid="2" mytitle="新闻2" />
<project myid="3" mytitle="新闻3" />
</newsid>
</data>
