IE下JS读取xml文件示例代码

function createDom() {
var xmlDoc = null;
try { //IE
if (typeof arguments.callee.activeXString != 'string') {
var versions = [
"MSXML2.DOMDocument.6.0",
"MSXML2.DOMDocument.3.0",
"MSXML2.DOMDocument",
"Microsoft.XMLDOM"
];
var i,
len;
for (i = 0, len = versions.length; i < len; ++i) {
try {
new ActiveXObject(versions[i]);
arguments.callee.activeXString = versions[i];
break;
} catch (ex) {
// ignore
}
}
}
xmlDoc = new ActiveXObject(arguments.callee.activeXString);
} catch (ex) { // other
xmlDoc = document.implementation.createDocument("", "", null);
}
return xmlDoc;
}

var xmldom = document.implementation.createDocument(namespaceUri, root, doctype);

function loadXML(file) {
var dom = createDom();
if (dom == null) {
alert("load filed!");
}
try {
dom.async = false;
dom.load(file);
} catch (ex) {
alert("unsupport browser!");

return dom;
}

var xmlDom = loadXML("config.xml");
