Using GET and POST

Using GET and POST

Hi. I´m trying to send parameters to a site and get an xml response. The problem is that I dont get anything into my response. Any ideas why? This is how it looks like:

  1. method: function(){
  2.         $.ajax({
  3.             type: "POST",
  4.             url: 'target_page',
  5.             data: "arg0=do&arg2=more",
  6.             dataType: 'xml',
  7.             complete: function(xml){
  8.                 $(xml).find('existingTagName').each( function(){
  9.                     alert("something found!");
  10.                 })
  11.                  alert("xml="+xml);
  12.             }
  13.         })
  14.     }
"something found" are never showing up but I get "xml=[object XMLHttpRequest]".
Can you see anything wrong with my code? Is it "POST" I am supposed to use?
