php - 在 PHP 中解析 xml 并删除一个节点

Question

我试图解析 XML 并从 XML 中删除节点“displayTextFlow”。下面是我的代码：

$filePath = file_get_contents('sample.xml');
$xml = new SimpleXMLIterator($filePath);
$iterator = new RecursiveIteratorIterator($xml, RecursiveIteratorIterator::SELF_FIRST);
foreach ($iterator as $key => $element) {
    if ($key == 'displayTextFlow') {
        unset($iterator[$key]);
    }
}
$finalXML = $xml->asXML();
print_r($finalXML);
exit;

在我的示例 XML 中，我不确定标签“displayTextFlow”的确切位置。它可能出现在任何其他地方。所以我需要编写一个代码来解析 XML 并删除所有地方的标签“displayTextFlow”注意：我只需要使用 SimpleXMLIterator 来完成它。

请检查示例 XML：

<?xml version="1.0"?>
