如何将标记xml行写入正确的位置？ <newWord><Heb>bull</Heb><Eng>bu</Eng></newWord>
当我运行代码时，我收到错误。“第1行第1行的错误：文档为空”错误？
如何添加标记<newWoed> id = 1，id = 2，如<newWoed id=3>？

非常感谢您的帮助。

xml文件：

<?xml version="1.0" encoding="windows-1255"?>
<Favorite_Word xml:lang="EN"><newWord><Heb>bull</Heb><Eng>bu</Eng></newWord>

<newWord>
    <Heb>Cow</Heb>
    <Eng>Co</Eng>
</newWord>
<newWord>
    <Heb>Camel</Heb>
    <Eng>Ca</Eng>
</newWord>
<newWord>
    <Heb>Bull</Heb>
    <Eng>BUl</Eng>
</newWord>

</Favorite_Word>

php文件：

function addElementToXml($doc='')
{
    if(!$doc)
    {
        $doc = new DOMDocument();
        // we want a nice output
        $doc->formatOutput = true;
        $doc->load('Dictionary_user.xml');
    }
    $Dictionary_user = $doc->documentElement;
    #var_dump($Dictionary_user->childNodes->item(0)->parentNode->nodeName);
    $newWord = $doc->createElement('newWord');
    #$newWord->setAttribute('isbn','http-equiv="Content-Type" content="text/html; CHARSET=windows-1255"');


    $prop = $doc->createElement('Heb','bull');
    $newWord->appendChild($prop);
    $prop = $doc->createElement('Eng','bu');
    $newWord->appendChild($prop);


    $Dictionary_user->childNodes->item(0)->parentNode->insertBefore($newWord,$Dictionary_user->childNodes->item(0));
    header("Content-type: text/xml");
    echo $doc->saveXML();
    $doc->save("Dictionary_user.xml");
}
    addElementToXml();

如果收到错误消息：

DOMDocument::load(): Document is empty in Dictionary_user.xml, line: 1 in foo.php on line 10

这意味着它要么读错了文件。或者文件只是空的。

要添加ID，您只需在要创建的节点上调用setAttribute。

$newWord = $doc->createElement('newWord');
$newWord->setAttribute('id','1');
