在PHP中追加XML节点

嗨有人可以帮助我在PHP中修改以下XML文档。在PHP中追加XML节点

的主要原因是这个问题我想和标签名称的虚拟XML节点追加为Service到事件>>车身>>服务>> ServiceInstalls

下面是XML文档

<Event> 
    <Header> 
     <EventSource>TXT</EventSource> 
    </Header> 
    <Body> 
     <Services>

       </ServiceInstalls> 
       <ServiceDisconnects/> 
      </ServiceChanges> 
     </Services> 
    </Body> 
</Event>

我已经尝试了代码，这样，但是我得到错误

$ str是什么，但上面的XML

$result = simplexml_load_string($str); 
$result = $result->xpath('/Event/Body/Services/ServiceChanges/ServiceInstalls'); 
$result = $result->addChild('Service',''); 

echo $result;

错误是

致命错误：调用一个成员函数的addChild（）上阵列中C：\ XAMPP \ htdocs中\ xhe2e \上线info.php的
第107行是$ result = $ result-> addChild（'Service'，''）;

显示你试图得到什么附加的孩子。你有没有读过任何相关的问题/答案，如这一个：http://stackoverflow.com/questions/31144422/append-xml-to-domnode-in-php?rq=1或这一个：http：///stackoverflow.com/questions/40139917/append-child-to-xml-based-on-attribute-of-the-parent-node-in-php?rq=1 –

@cale_b我用我的尝试更新了这个问题，你能帮助我需要做什么来解决问题 – Batman

你错过了在尝试一个微妙的项目：

$result = simplexml_load_string($str); 
$result = $result->xpath('/Event/Body/Services/ServiceChanges/ServiceInstalls'); 
// $result should now be an array. Check to be sure: 
if ($result && is_array($result)) { 
    // since it IS an array, set to the first element of the array 
    $result = $result[0]; 
    // And NOW we can append 
    $result = $result->addChild('Service',''); 
} 

// The part from here is only to make the output pretty-xml 
// instead you can just use $result->saveXML() 
$dom = new DOMDocument("1.0"); 
$dom->preserveWhiteSpace = false; 
$dom->formatOutput = true; 
$dom->loadXML($result->saveXML()); 
var_dump($dom->saveXML());

现在我没有看到任何错误，但没有看到任何回应也。您能否请检查 – Batman

是的，抱歉，无法回应它 - 需要先将它再次保存到XML。 –

我得到的答复作为字符串（33）在响应，而不是'var_dump'我想用'回声'获得响应作为字符串，但它不工作你能帮助这里 – Batman

$sxe = new SimpleXMLElement($xmlstr); 
$result = $sxe->xpath('/Event/Body/Services/ServiceChanges/ServiceInstalls'); 
$result = $result[0]; 
$result = $result->addChild('Service','Dummy'); 

echo $sxe->asXML();

我能够用这种方式
