생략 네임 스페이스 접두사 SimpleXML을

Question

를 사용하여 XML을 생성 할 때 나는 다음과 같은 한 코드

$base = '<?xml version="1.0" encoding="UTF-8"?><realestates:office xmlns:realestates="http://rest.immobilienscout24.de/schema/offer/realestates/1.0" xmlns:xlink="http://www.w3.org/1999/xlink"></realestates:office>'; 

$objXml = new \SimpleXMLElement($base); 
$objXml->addChild('title', 'Alles Toller'); 
$strXml = $objXml->asXML(); 

는

$strXml 지금

<?xml version="1.0" encoding="UTF-8"?> 
<realestates:office xmlns:realestates="http://rest.immobilienscout24.de/schema/offer/realestates/1.0" xmlns:xlink="http://www.w3.org/1999/xlink">  
<realestates:title>Alles Toller</realestates:title> 
</realestates:office> 

내가 원하는 것은이 <title>

<?xml version="1.0" encoding="UTF-8"?> 
<realestates:office xmlns:realestates="http://rest.immobilienscout24.de/schema/offer/realestates/1.0" xmlns:xlink="http://www.w3.org/1999/xlink">  
<title>Alles Toller</title> 
</realestates:office> 

에 realestates: 접두사를 가지고 있지하는 것

어떻게하면됩니까?
