parseerror in jQuery when returning xml from mod_python

Frage

I'm trying to return XML-data from a Python script using jQuery's .ajax:

<html><head>
  <script type="text/javascript" src="jquery-1.7.2.js"></script>
  <script type="text/javascript">
    $(document).ready(function() {
      $.ajax({
        type: "POST",
        url: "script.py/method",
        dataType: "xml",
        success: function(xml) { alert('Success!'); },
        error: function(request, error) { alert(error); }
      });
    });
   </script>
 </head><body></body></html>

When my script.py returns nothing the alert show Success!, but as soon as I try to add some XML data all I get is parseerror. How should I do to return XML without getting a parseerror?

script.py - working

def method(req):
    req.content_type = 'text/xml'
    req.write('')  # Works!

script.py - broken

def method(req):
    req.content_type = 'text/xml'
    req.write('<item>1</item><item>2</item>') # parserror!
War es hilfreich?

Lösung

Your xml isn't valid, you are missing a root node(a single root node), eg

def method(req):
    req.content_type = 'text/xml'
    req.write('<items><item>1</item><item>2</item></items>')
