When I use the below code and parse the xml locally it works fine but when upload the same script at the server it shows error.

On each loop of the result set, you're appending a new root element to the document, creating an XML document like this:

An XML document can only have one root element, which is why the error is stating there is "extra content". Create a single root element and add all the mycatch elements to that:

$root = $dom->createElement("root");
$dom->appendChild($root);
// ...
while ($row = @mysql_fetch_assoc($result)){
  $node = $dom->createElement("mycatch");
  $root->appendChild($node);
