loadxmldoc.js文件内容



function createXMLDoc(){
    var xmldoc;
    try {
        xmldoc = new ActiveXObject("Microsoft.XMLDOM");
        if(!xmldoc) xmldoc = new ActiveXObject("MSXML2.DOMDocument.3.0");

    if(!xmldoc) {
        return null;
    } else{
        xmldoc.async = "false";
        if(xmldoc.parseError.errorCode == 0 ) {
            return xmldoc;
        } else {
            return null;
        }
    }
   
}

function loadXMLDoc(dname) {//文档 如books.xml
    var xmlDoc=createXMLDoc();

    xmlDoc.async = "false";
    xmlDoc.load(dname);
    return (xmlDoc);
}
function loadXMLString(text) {//字符串
    var xmlDoc=createXMLDoc();
    xmlDoc.async = "false";
    xmlDoc.loadXML(text);

实例
var root=xmlDoc.documentElement;
