jQuery Forum

I'm trying to access an XML file, but it doesn't seem to work, this is an example of the XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<pics>
   <pic>
      <autor>rtteewt</autor>
      <desc>trhtrhtreherhetrhhrh</desc>
   </pic>
   <pic>
      <autor>tewtewt</autor>
      <desc>hytjyujryukukyyu.</desc>
   </pic>
   <pic>
      <autor>5yutru</autor>
      <desc>fghgyhvehtyudyd</desc>
   </pic>
   <pic>
      <autor>jhgjgfj</autor>
      <desc>trhythtrjtikui</desc>
   </pic>
</pics>


This is a simple jquery function I'm using just to check if Im able to read the content:

var total = 0;
function readXML(section)
   var xml = $.ajax(
   {
      type: "GET",
      url : "xmldocs/picslist.xml",
      dataType: "xml",
      success: function(xml)
      {

            total = xml.getElementsByTagName("pic").length;

      }
   });
   alert(total);
}   


I'm getting 0 all the time...
