<channel>
<area id="1">
<city name="珠海" />
<city name="深圳" />
<city name="中山" />
</area>
<area id="2">
<city name="成都" />
<city name="广安" />
</area>
<area id="3">
<city name="武汉" />
<city name="宜昌" />
</area>
<area id="4">

<option value="2">四川</option>
<option value="3">湖北</option>
<option value="4">湖南</option>
</select>

<script type="text/javascript" src="scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript">
function getson(fpath, vals) {
$.ajax({
type:
'GET',
url: fpath,
dataType:
'xml',
beforeSend:
function () {
$(
'#son').empty();
},
success:
function (data) {
$(data).find(
"area[id='" + vals + "']>city").each(
function () {
var son = $(this).attr("name");
$(
"#son").append('<option value="' + son + '">' + son + '</option>');
}

function () {
