在Javascript中加载XML数据时出错

我在用Javascript加载XML数据时遇到了一个问题。但是,如果我在经典ASP中加载相同的XML,它就可以工作,但是如果我在Javascript中加载相同的XML,它就失败了。

set ObjXMLDom = nothing 
set ObjXMLDom = server.CreateObject("Microsoft.XMLDOM")
ObjXMLDom.async = False

set objSvr = Server.CreateObject("myComMethod.MyComMethod.1")
ObjXMLDom.loadXML(objSvr.GetHierarchyXML()) 'XML loads perfectly fine from server. even if the special character is Dash –
Response.Write(ObjXMLDom.xml) 

用Javascript编写代码来加载XML,但是对于某些特殊字符它失败了。

$.ajax("get_xml_from_server.asp", {
                type: 'GET',
                data: { name: groupID, session: sesionID, Employee: empID },
                beforeSend: function () {
                },
success: function (data, status, jqXhr) {

//Data has got the XML string, we can see it by putting alert

alert(data); 

var myXML = new ActiveXObject("Microsoft.XMLDOM");
myXML.async = false;
myXML.loadXML(data); //Here it fails for some special characters like Dash – 


if (myXML.parseError.errorCode != 0) 
      {
          var myErr = myXML.parseError;
          alert("You have error " + myErr.reason + myErr.line + myErr.srcText);
      } 
else  {
          alert(myXML.xml);
      }
