$.Ajax won't initiate success function

$.Ajax won't initiate success function

I'm trying to make a function that loops through an XML file to display the data on a page. However when I try to load the file, the $.Ajax function breaks and nothing happens.

  2. $(document).ready(  
  3.   function(){
  4. $.ajax({
  5. url:"portfolio.xml",
  6. type:"POST",
  7. dataType:"xml",
  8. success:loadData,
  9. error:function(msg){
  10. alert(msg);
  11. }
  12. });
  13. });
That shouldn't be breaking, but I don't know what's happening.
