js操作xml心得

    <script language="javascript" type="text/javascript" src="sg_share.js"></script>
    <script language="javascript">
        function test()
        {
            //var doc= new ActiveXObject("Microsoft.XMLDOM");
            alert("ok");

            var doc=sg.xmlDocument();
            var returnXml="<Root Caption=\"trues\"></Root>"; 
            doc.loadXML(returnXml);
      
            var r=doc.selectSingleNode("Root");
            alert(r.getAttribute("Caption"));
//            for(int i=0,j=r.attributes.length;i<j;i++)
//            {
//                alert(r.attributes[i].value);
//            }

            var flag=r.getAttribute("Caption");
            if(flag=="trues")
                alert("注册成功！");
            else
                alert("注册失败！");
        }

        window.onload=function()
        {
            test();
        }
    </s

下面是sg_share.js中xmlDocument代码

    this.xmlDocument = function()
    {
        var xmldoc = null;
        if(typeof(window.ActiveXObject) != 'undefined')
        {    
            try
            {
                //xmldoc = new ActiveXObject("MSXML2.DOMDocument.5.0");
            }
            catch(e)
            {
            
            }
            if(xmldoc==null)
                xmldoc = new ActiveXObject("Microsoft.XMLDOM");
        }
        else
        {
            xmldoc = document.implementation.createDocument("", "doc", null)
        }
        return xmldoc;    
    }
