[解决办法]
参考以下JS代码：
var xmlDoc = new ActiveXObject( "Msxml2.DOMDocument.3.0 ");
var elems;
xmlDoc.async = false;
xmlDoc.resolveExternals = false;
xmlDoc.load( "xxx.xml ");
if (xmlDoc.parseError.errorCode == 0) {
elems= xmlDoc.selectNodes( "//TD ");
for(var i=0;i <elems.length;i++)
elems[i].setAttribute( "NAME ", "TD "+i)

alert(xmlDoc.xml);
}

[解决办法]
nodeElem.SetAttribute( "attr ", "attrValue ");//添加属性节点
