DOMDocument、getNamedItem和nodeValue

Question

我得了Fatal error: Call to undefined method DOMElement::getNamedItem()，但我不知道为什么。关于DOMdocument这件事我肯定有些不明白。下面是我的代码：

// load content of db
$dom = new DOMDocument('1.0');
$dom->load($file);

// make domnodelist with girls
$girls = $dom->getElementsByTagName('girl');

foreach($girls as $girl)
{
    $username = $girl->getNamedItem('username');
    echo $username->nodeValue;
}

下面是我的xml：

<root>
  <girl username="xxxx" id="2012111003051009">
    <url>xxxx</url>
    <replied>false</replied>
    <thumbnail>dbs/db-thumbnails/xxxx.jpeg</thumbnail>
    <blacklisted>false</blacklisted>
    </girl>
</root>

Answer 1

username是DOMElement $girl的属性。因此，您需要使用的是getAttribute。

foreach($girls as $girl)
{
    $username = $girl->getAttribute('username');
    // or if using getNamedItem 
    // $username = $girl->attributes->getNamedItem ('username')->nodeValue
    echo $username;
}
