RE: LoadXML trouble

["ked" <kd@xxxxxxxxxxx>]

first, create "dealxml.php" with ansi charset : 
<?php
$r =
<<<XML
<?xml version="1.0"?>
<response>
  <customerID>ked</customerID> 
  <appName>tickcenter</appName> 
  <ticketType>train</ticketType> 
  <ticketAction>back</ticketAction> 
  <ticketID>1197026188_ec76</ticketID> 
  <status>KO</status> 
  <errCode>500</errCode> 
  <errMsg>Internal Server Error</errMsg> 
</response>
XML;
$xml = new DOMDocument();
//$xml->validateOnParse = true;
$xml->loadXML( $r );
$customer_id   = $xml->getElementsByTagName( 'customerID' )->item( 0
)->nodeValue;
$app_name      = $xml->getElementsByTagName( 'appName' )->item( 0
)->nodeValue;
$ticket_type   = $xml->getElementsByTagName( 'ticketType' )->item( 0
)->nodeValue;
$ticket_action = $xml->getElementsByTagName( 'ticketAction' )->item( 0
)->nodeValue; 
$ticket_params = $xml->getElementsByTagName( 'parameters' )->item( 0
)->childNodes;
echo "$customer_id <br>";
echo "$app_name <br>";
echo "$ticket_typed <br>";
echo "$ticket_action <br>";
echo "$ticket_params <br>";
?>

IE output :  

Warning: DOMDocument::loadXML() [function.loadXML]: Input is not proper
UTF-8, indicate encoding ! in Entity, line: 4 in W:\www\test\dealxml.php on
line 26

next , saved the dealxml.php as UTF-8 charset, then it works well.

I think that  the xml resource should be encoded by utf-8 charset, right or
wrong  ?  

My OS : win2000 , simplified chinese. Dose the OS blight  "DOMDocument" ?
