如何在PHP中从XML中删除DOM元素？

以下是我的XML文件内容

现在我想从xml中删除元素，我该怎么做呢

$doc = new DOMDocument; 
$doc->load("XML FILE");
$thedocument = $doc->documentElement;
$list = $thedocument->getElementsByTagName('text');
foreach ($list as $domElement){
    //Code to remove current text element... 
}

你看过说明书了吗？您可以使用removeChild。美国有一个例子

<?php

$doc = new DOMDocument;
$doc->load('book.xml');

$book = $doc->documentElement;

// we retrieve the chapter and remove it from the book
$chapter = $book->getElementsByTagName('chapter')->item(0);
$oldchapter = $book->removeChild($chapter);

echo $doc->saveXML();
?>

$DOMELENT->parentNode->removeChild$DOMELENT；
