Question

嗨有人可以帮我修改PHP下面的XML文档。

这个问题的主要原因是我想在EVent＆gt;＆gt; Body＆gt;＆gt;服务＆gt;＆gt; ServiceInstalls

中添加标记名为Service的虚拟XML节点

以下是XML文档

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

我已经尝试过这样的代码，但是我收到了错误

$ str只不过是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：在 107 C：\ xampp \ htdocs \ xhe2e \ info.php 上的数组上调用成员函数addChild（）
第107行是$ result = $ result-＆gt; addChild（＆＃39;服务＆＃39;，＆＃39;＆＃39;）;

Answer 1

你错过了一个微妙的项目：

$result = simplexml_load_string($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());

Answer 2

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

echo $sxe->asXML();

我能够以这种方式获得附加的孩子
