dom - javascript code doesnt work in browser -


i have code , using pspad editor when programing. when run "html page preview" in pspad works when try open in browser does't work. on chrome alerts "undefined not function". on firefox prints undefined , alerts empty window. on internet explorer nothing. can give me simple answer code example if possible?(this code should print content of xml)

<!doctype html> <html>     <head>     <script src="loadxmldoc.js"></script>     <script src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>      </head>     <body>         <script>             var xmldoc= loadxmldoc('skoly.xml');              var d = document.createelement('div');              var t = document.createtextnode(xmldoc.xml);              d.appendchild(t);             document.write('<pre>' + d.innerhtml + '</pre>');              alert(xmldoc.xml);         </script>     </body> </html>

loadxmldoc.js:

function loadxmldoc(dname) {     try { //internet explorer         xmldoc=new activexobject("microsoft.xmldom");     } catch(e) {         try { //firefox, mozilla, opera, etc.             xmldoc=document.implementation.createdocument("","",null);         } catch(e) {             alert(e.message)         }     }     try {         xmldoc.async=false;         xmldoc.load(dname);         return(xmldoc);     } catch(e) {         alert(e.message)     }     return(null); }

this part returning error:

alert(xmldoc.xml);

i'm not sure trying achieve code trying return property "xml" of variable "xmldoc". in other words, work if xmldoc object looks this: 

var xmldoc = {     xml: "something here" };

it returning "cannot read property 'xml' of null" because xmldoc has value null , trying return property.
