从Plex Media Server获取XML数据

Question

我希望通过foreach从Plex Media Server获取信息。我已成功从URL中获取内容，但我无法获取要在页面上打印的信息。

这是来自URL的var_dump：

object(SimpleXMLElement)[1]
  public '@attributes' => 
    array
      'size' => string '349' (length=3)
      'mediaTagPrefix' => string '/system/bundle/media/flags/' (length=27)
      'mediaTagVersion' => string '1322272914' (length=10)
      'sortAsc' => string '1' (length=1)
      'viewGroup' => string 'movie' (length=5)
      'viewMode' => string '458803' (length=6)
      'art' => string '/:/resources/movie-fanart.jpg' (length=29)
      'title1' => string 'Filmer' (length=6)
      'identifier' => string 'com.plexapp.plugins.library' (length=27)
  public 'Video' => 
    array
      0 => 
        object(SimpleXMLElement)[2]
          public '@attributes' => 
            array
              ...
          public 'Media' => 
            object(SimpleXMLElement)[351]
              ...
          public 'Genre' => 
            array
              ...
          public 'Writer' => 
            array
              ...
          public 'Director' => 
            object(SimpleXMLElement)[356]
              ...
          public 'Country' => 
            object(SimpleXMLElement)[357]
              ...
          public 'Role' => 
            array
              ...
  1 => 
    object(SimpleXMLElement)[3]
      public '@attributes' => 
        array
          ...
      public 'Media' => 

And so on...

这是来自URL的print_r数据：

När han ber att få gå på skolbalen med henne får han dock veta att hennes pappa har bestämt att hon inte får gå på dejt så länge Biancas syster Kat är singel. Kat är ständigt på dåligt humör och ovänlig och definitivt inte någon man vill gå på dejt med. Cameron måste också konkurrera om Biancas gunst med snyggingen Joey. Cameron kommer då på en plan: att be Pat, som enligt ryktet har sålt sin lever för att köpa högtalare, att gå med Kat på skolbalen mot betalning.

这是我现在的代码：

$url = 'http://localhost:32400/library/sections/12/all';
$achxml = simplexml_load_file($url);
foreach($achxml->attributes AS $ach) {
    echo $ach->Video['title'].'<br>';
}

我唯一能摆脱这一点的是......好吧 - 没事！它根本不打印任何东西！所以我现在问你，我的foreach有什么问题？您可以在此处详细了解PlexNine或他们现在称之为的内容：http://wiki.plexapp.com/index.php/PlexNine_AdvancedInfo

提前致谢。

我现在就开始工作了！这是解决方案：

foreach($achxml->Video AS $child) {
    echo $child['title'];
}
