Question

我正在尝试解析具有以下格式的XML：

<lfm status="ok">
  <album>
    <name>Babel</name>
    <artist>Mumford And Sons</artist>
    <id>310716066</id>
    <mbid/>
    <url>
      http://www.last.fm/music/+noredirect/Mumford+And+Sons/Babel
    </url>
    <releasedate></releasedate>
    <image size="small">http://userserve-ak.last.fm/serve/34s/85199619.jpg</image>
    <image size="medium">http://userserve-ak.last.fm/serve/64s/85199619.jpg</image>
    <listeners>4621</listeners>
    <playcount>151324</playcount>
    <tracks></tracks>
    <toptags>
      <tag>
        <name>indie</name>
        <url>http://www.last.fm/tag/indie</url>
      </tag>
    </toptags>
  </album>
</lfm>

但是当我这样做时：

//Chamar a API do Last.FM
$album_response = file_get_contents("http://ws.audioscrobbler.com/2.0/?method=album.getinfo&api_key=9ba08c332660c8e23d8612e296696236&artist=$artista&album=$album");

//Criar um DOMDocument
$xml= new DOMDocument('1.0', 'ISO-8859-1');
$xml->loadXML($album_response);

//Ver se o álbum existe
$encontrou_album = $xml->getElementsByTagName("lfm")->item(0)->getAttribute("status");

最后一行不起作用。有关如何检索该属性的任何想法？

PHP获取属性
