IE VS NETSCAPE[14]

var xmlserverhttp = new activexobject("msxml2.xmlhttp");

ie 支持:xmldoc.load(filename) 和 xmldoc.loadxml(string)

ns只支持xmldoc.load(filename)方法

if (navigator.appname =="microsoft internet explorer")  //ie

    {  

        var xmldoc = new activexobject("msxml2.domdocument");

        var xmlserverhttp = new activexobject("msxml2.xmlhttp");      

        xmldoc.async = false;

        xmldoc.loadxml(xmlstr);

        xmlserverhttp.open("post",tourl, false);
