js解析xml的问题，

你的xml中有#，我这边解析不出，故给删了<html>

<SCRIPT>
function fnCheck(){

刚才文档有问题.
这是页面加载XML ,若要用ajax ，将oMetaData.XMLDocument换一下responseXML就可以了<html>
<body>
<SCRIPT>
function fnCheck(){
var doc=oMetaData.XMLDocument;
var ARCXML_item=doc.getElementsByTagName("ARCXML")[0];
var RESPONSE_item=ARCXML_item.getElementsByTagName("RESPONSE")[0];
var FEATURES_item=RESPONSE_item.getElementsByTagName("FEATURES")[0];
var FEATURE_item=FEATURES_item.getElementsByTagName("FEATURE")[0];
var MULTIPOINT_item=FEATURE_item.getElementsByTagName("MULTIPOINT")[0];var FIELDS_item=FEATURE_item.getElementsByTagName("FIELDS")[0];
var POINT_item=MULTIPOINT_item.getElementsByTagName("POINT")[0];document.getElementById("show").value="<a onclick=\"test('"+POINT_item.getAttribute("x")+"','"+POINT_item.getAttribute("y")+"')\">"+FIELDS_item.getAttribute("OBJPOS")+" </a> ";}

另外，lz的xml有问题：带有特殊符合#(我已处理掉，可看我的源码)
<FIELDS ID="6" OBJCODE="5101050101020022" OBJNAME="abcd" DEPTCODE="51010042" DEPTNAME="efgh" MATERIAL="" GBCODE="51010500300101" OBJPOS="keywords" OBJSTATE="ok" USESTATE="on" CRDATE="1146009600000" CHDATE="-2211753600000" MAPSCALE="500" MEMO=""  #SHAPE#="[Geometry]" #ID#="6" />
【个人意见，仅供参考】
1.把xml保存成一个文件如a.xml,
2.修改里面的错误，去掉井号，还有FIELDS ID="6"的ID重复了，去掉。
3.写一个b.htm,内容如下：<script language="javascript">
function loadXML(xml){
   var doc = null;
   if (window.ActiveXObject){
       doc = new ActiveXObject('Msxml2.DOMDocument');
       doc.async=false;
       doc.load(xml);
   }
   else if (document.implementation && document.implementation.createDocument){
       var xmlhttp = new window.XMLHttpRequest();
       xmlhttp.open("GET",xml,false);
       xmlhttp.send(null);
       doc = xmlhttp.responseXML.documentElement;
   }
   return doc;
}function GetPointList(){
var doc = loadXML('a.xml');
if( doc == null)
return null;

//2.create data array
var pts = doc.getElementsByTagName('POINT');
if( pts == null || pts.length <= 0)
return null;

var count = pts.length;
var ret = new Array(count);
for(var i=0; i<count; i++){
ret[i] = new Array(2);
ret[i][0] = pts[i].getAttribute('x');
ret[i][1] = pts[i].getAttribute('y');
}
return ret;
}function ParseXML(o){
var pts = GetPointList();
var bHasRecord = (pts != null) && (pts.length >= 0);
var html = '';
if( bHasRecord ){
for(var i=0; i<pts.length; i++){
html += '<a href="#" onclick="test(\''+pts[i][0]+'\',\''+pts[i][1]+'\')">keywords </a> <br>';
}
}
o.innerHTML = html;
}function test(x,y){
alert('('+x+','+y+')');
}
</script>
<body onload="ParseXML(document.body)">
</body>

参考一下
我补充一下，如果这个xml是一个字符串形式的变量，而不能存放在服务器端，而且里面的

<POINT x="104.060846680346" y="30.6786616511078"/>

</FEATURE> 这一部分是重复的不同的元素，怎么办呢？
