}
}
function state_Change()
{
if (xmlhttp.readyState==4)
{// 4 = "loaded"
if (xmlhttp.status==200)
{// 200 = "OK"
document.getElementById('A1').innerHTML=xmlhttp.status
document.getElementById('A2').innerHTML=xmlhttp.statusText
document.getElementById('A3').innerHTML=xmlhttp.responseText

可以修改，我对JS并不是非常熟悉，给你一段代码参考一下。<script>var xmldom
function test()
{
xmldom = new ActiveXObject("Msxml2.DOMDocument")
xmldom.async = false
xmldom = document.all.mxh.XMLDocument
}
function test2()
{
var xmldom = new ActiveXObject("Msxml2.DOMDocument")
xmldom.async = false
xmldom = document.all.mxh.XMLDocument
node = xmldom.selectSingleNode("//nodeB")
node2 = xmldom.createElement("nodeB")
node2.text=parseInt(node.text)+1
xmldom.documentElement.replaceChild(node2,node)
node = xmldom.selectSingleNode("//nodeB")
alert(node.text)
alert(xmldom.xml)
}
function test3()
{
document.f.xmldata.value= document.all.mxh.XMLDocument.xml
alert(document.f.xmldata.value)
document.f.submit()
}
</script>
<body>
<XML id=mxh>
<root>
<nodeA>nodeA</nodeA>
<nodeB>30</nodeB>
</root>
</XML>
<form name=f action="xx.asp">
<input name=xmldata type=hidden>
<input onclick="test()" type="button" value=old>
<input onclick="test2()" type="button" value=请多点几次>
<input onclick="test3()" type="button" value=保存>
</form>
保存，调用 xmldom.save("xxx.xml")
