Error #1085: The element type "elements" must be terminated by the matching end-tag " /elements "." faultCode="Client.CouldNotDecode"

Question

Hello everyone,
I'm using an httpservice with a php script and resultformat "e4x".
When I call my script directly in my browser, I receive a well formatted XML file (I think so as I can even see the closing tag </elements>).
But, in my application, the debugger gives me the error saying that the end-tag is not there...
Can you please help me?
Here's the script:
<?php
//Set no caching
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); 
header("Content-Type: text/xml");
// Connect to MySQL database
require_once('database/ConnectDB.php');
mysql_select_db($database_ConnectDB, $ConnectDB);
function DisplayElements($zone_id){
    $query = "
            SELECT
                element.element_id, element.name, element.description, element.zone_id, actval
                FROM element
                LEFT JOIN elm_motor USING (element_id)
                LEFT JOIN modregister USING (element_id)
                LEFT JOIN module USING (module_id)
                WHERE element.type_sw_id = 602
                AND module.status >= 128 AND element.zone_id = $zone_id
                GROUP BY element.element_id ORDER BY name
        $result = mysql_query($query) or die(mysql_error());
    while($data=mysql_fetch_assoc($result)){
        echo '<element id="'.$data['element_id'].'" name="'.$data['name'].'" description="'.$data['description'].'" zone_id="'.$data['zone_id'].'" actval="'.$data['actval'].'" prefval="'.$data['prefval'].'"/>';
$zone_id = $_POST["zone_id"];
echo '<elements>';
DisplayElements($zone_id);
echo '</elements>';
?>
Thank you very much,
a beginner...

Answer 1

The problem is that your PHP script is only going to provide a single response, so the second echo never gets to your Flex app.
Store the result in a variable and echo that:
$returnVal = "<elements>";
... code to add elements
$returnVal = "</elements>";
echo $returnVal;
