用javasctipt写一个dom对一个xml文件进行操作

var m = new ActiveXObject("MSXML2.DOMDocument");
m.loadXML('<Jobs><Jobdata name="Joe"><job>Programmer</job><department>Engineering</department><cubicle>5E</cubicle></Jobdata><Jobdata name="Erin"><job>Designer</job><department>Marketing</department><cubicle>9M</cubicle></Jobdata></Jobs>');
var b = m.getElementsByTagName("Jobdata");
for(var i=0;i<b.length;i++)
if (b[i].childNodes[0].childNodes[0].nodeValue == "Programmer")
b[i].childNodes[1].childNodes[0].nodeValue = "software Support";
alert(m.xml);

假设xml文件保存为xmlsrc.xml：
------------------------------
var dom = new ActiveXObject("MSXML.DOMDocument");
dom.load("xmlsrc.xml");
var oNodes = dom.selectNodes("//Jobdata[job='Programmer']");
var i;
for(i=0;i<=oNodes.length-1;i++)
{
oNodes[i].childNodes[1].text='software Support';
}
这样改了之后，如何保存呀？我的source.xml文件的内容还是没有变呀？？？
dom.save(path);我用的是用DOM的作法,我楼下的是用xpath
dom.save("source.xml")
不管用呀。
<html>
<body>
<script language="javascript">
var m = new ActiveXObject("MSXML2.DOMDocument");
m.loadXML('<Jobs><Jobdata name="Joe"><job>Programmer</job><department>Engineering</department><cubicle>5E</cubicle></Jobdata><Jobdata name="Erin"><job>Designer</job><department>Marketing</department><cubicle>9M</cubicle></Jobdata></Jobs>');
var b = m.getElementsByTagName("Jobdata");
for(var i=0;i<b.length;i++)
if (b[i].childNodes[0].childNodes[0].nodeValue == "Programmer")
b[i].childNodes[1].childNodes[0].nodeValue = "software Support";
alert(m.xml);
dom.save("source.xml")
</script>
</body>
</html>
运行之后，在IE的状态栏上报：“已完毕，但网页上有错”
本地是没有这个权限,用HTA可以,或在服务端
不好意思，请问 HTA什么意思呀？服务端又是什么意思呀？

WriteToFile(dom.xml,"C:\\source.xml")
