从Plex Media Server获取XML数据

Question

I want to get information from Plex Media Server trough foreach. I have succeeded fetching the content from an URL but I can't get the information I want to print out on the page.

This is the var_dump from the URL:

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...

This is the print_r data from the URL:

SimpleXMLElement Object ( [@attributes] => Array ( [size] => 349 [mediaTagPrefix] => /system/bundle/media/flags/ [mediaTagVersion] => 1322272914 [sortAsc] => 1 [viewGroup] => movie [viewMode] => 458803 [art] => /:/resources/movie-fanart.jpg [title1] => Filmer [identifier] => com.plexapp.plugins.library ) [Video] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [ratingKey] => 2663 [key] => /library/metadata/2663 [studio] => Touchstone Pictures [type] => movie [title] => 10 Things I Hate About You [contentRating] => PG-13 [summary] => "10 Things I Hate About You" är en amerikansk långfilm från 1999 i regi av Gil Junger. När Cameron börjar high school förälskar han sig snabbt i den söta Bianca. Han hjälper henne med hemläxorna i franska för att få henne att bli intresserad av honom. 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.

This is the code I have right now:

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

The only thing I getting out of this is... well - nothing! It doesn't print out anything at all! So I'm asking you now, what's wrong with my foreach? You can read more about PlexNine or what they now calling it, here: http://wiki.plexapp.com/index.php/PlexNine_AdvancedInfo

Thanks in advance.

Answer 1

I got this working now! Here's the solution:

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