How to catch XML packets that ConsoleExport Firebug extension sends?

I have installed ConsoleExport Firebug extension. I have enabled auto-export feature at about:config by setting extensions.firebug.consoleexport.active to true. I have opened a page with JavaScript error, for example http://www.random.org. I have enabled Firebug, reloaded the page. I can see the error in log:

uncaught exception: Error: Permission denied for <https://www.facebook.com> to get property Proxy.InstallTrigger

The ConsoleExport page says:

You can also activate an auto-export feature that is sending individual logs into specified server as XML packets.

I know I should set extensions.firebug.consoleexport.serverURL to server URL. I do not know how to catch XML packets that ConsoleExport sends.

For example, I know how to set up Apache on Mac, but what then? How to catch XML packets?

Environment:

I have access to Windows and Linux machines, if the server that catches XML packets is easier to set up there.

It sounds like it simply sends the XML data via an AJAX request to that URL. So you need to define a script, that handles that XML data.

E.g. when you use PHP, you could set the serverURL preference to http://localhost/handleFBConsoleOutput.php. That script could then look like this:

<?php
  $filename = '/path/to/log/file/consoleexport.log';

  if (!$handle = fopen($filename, 'a'))
  {
    echo 'File "'.$filename.'" could not be opened';
    exit;
  }

  ob_start();
  var_dump($_POST);
  $content = ob_get_contents();
  ob_clean();

  if (!fwrite($handle, $content))
  {
    echo 'Can\'t write into file "'.$filename.'"';
    exit;
  }

  echo 'Done!';
  fclose($handle);
?>

The code shown here writes a dump of all POST parameters. You might want to specify the exact parameter as output by replacing the $content variable by $_POST['param_name'], where param_name is the name of the parameter holding the XML contents, and remove the ob_start(); ... ob_clean(); block.

As reference: The same issue was asked at the Firebug discussion group.

Modified script fixing a problem with getting the posted data:

Note that the content-Type of the posted data is application/xml

<?php
  $filename = 'consoleexport.log';

  if (!$handle = fopen($filename, 'a'))
  {
    echo 'File "'.$filename.'" could not be opened';
    exit;
  }

  ob_start();
  $content = file_get_contents('php://input');
  $content .= "\n";
  ob_clean();

  if (!fwrite($handle, $content))
  {
    echo 'Can\'t write into file "'.$filename.'"';
    exit;
  }

  echo 'Done!';
  fclose($handle);
?>
