Recommended Posts

im working on making a very simple xml loader class to load images from an xml file but im am recieving an access denied error where it says

this.xhttp.open "GET","images.xml",false);

heres all the code:

function xml_loader(){	
this.xhttp = null;	
this.xmlDoc = null; 	
this.get_xml = function(file){	
  if (window.XMLHttpRequest){ 
       this.xhttp=new XMLHttpRequest();  	
  }else{
       this.xhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
  this.xhttp.open("GET",file,false);
  this.xhttp.send("");
  this.xmlDoc=xhttp.responseXML;
  return this.xmlDoc;	
}
}
