他那个有个select联动,选项里数据来源也不是xml读入的，直接写在里面的。select联动的效果网上随便一搜就是一把。自己去搜搜，可参考http://www.waasai.com/s/cs/
<html>
<head>
  <script language="JavaScript">

</script></head>
<body >
<select name="sl" onChange="alert(this.value)"></select>

用DOM兼容麻烦可以用AJAX
按你给的XML可以这样解析...
<select id="sel"></select>
<script>
var xmlHttp = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('microsoft.xmlhttp');
var url = 'myxml.xml';
xmlHttp.open('get',url,true);
xmlHttp.onreadystatechange = parseXML;
xmlHttp.send(null);
function parseXML(){
if(xmlHttp.readyState == 4){
if(xmlHttp.status == 200){
var sel = document.getElementById('sel');
var rs = xmlHttp.responseXML.getElementsByTagName('subject')[0].getElementsByTagName('ratio');
for(var i=0; i<rs.length; i++){
var name = rs[i].firstChild.firstChild.nodeValue, value = rs[i].lastChild.firstChild.nodeValue
sel.options[sel.options.length] = new Option(name, value);
} }
}
}
</script>
ff ie测试通过：
<html>
<body>
<select id="Select1"></select>
<script type="text/javascript">
var select1 = document.getElementById("Select1");
var xmlhttp = typeof XMLHttpRequest == "undefined" ?
new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
xmlhttp.onreadystatechange = function(){
if (xmlhttp.readyState == 4) { // READY_STATE_COMPLETE = 4
var nodes = xmlhttp.responseXML.documentElement.getElementsByTagName("ratio");
for (var i = 0; i < nodes.length; i++) {
var name = nodes[i].getElementsByTagName("name");
var value = nodes[i].getElementsByTagName("value");
if (name.length && name[0].firstChild && value.length && value[0].firstChild) {
var option = document.createElement("option");
option.text = name[0].firstChild.nodeValue;
option.value = value[0].firstChild.nodeValue;
select1.appendChild(option);
}
}
}
}
xmlhttp.open("get", "temp.xml?version=1", true);
xmlhttp.send(null);
</script>
</body>
</html>
