PHP return Verschachtelte XML

Question

Ich erhalte XML aus einer Datei wie unten beschrieben. Wenn der XML-Code jedoch an der Stelle ".$image["url"]." tiefer wird, versuche ich eines der Bilder wiederherzustellen, aber es funktioniert nicht. Ich würde auch die Bilder suchen müssen, da es mehrere Variablen durch die Variable SIZE im XML gibt (XML unten).

Wie definieren Sie dies, nachdem ich den $ xml-> xpath bereits auf einen höheren Container definiert habe?

$searchurl = "movies.xml"; 
$xml = simplexml_load_file($searchurl); 
$i = 0; 
foreach($xml->xpath('/movies/movie') as $movie){ 
    $image = $xml->xpath('/movies/movie/images/image'); 
    echo "<table id=\"ctable\">" 
     ."<thead><tr><th>" 
     ."<th width=\"100%\"><a href=\"JavaScript:void(0);\" onclick=\"showHide('movie".$movie->id."','span".$movie->id."')\">" 
     ."<span id=\"span".$movie->id."\"><img src=\"images\icon_collapse.gif\" class=\"expand\" alt=\"Expand\"></span>" 
     ."<span>".$movie->name."</span></a></th>" 
     ."<th><span></span></th>" 
     ."</th></tr></thead>"; 
    echo "<table><tfoot id=\"movie".$movie->id."\">" 
     ."<tr><td rowspan=\"6\"><a class=\"thumbnail\" href=\"#thumb\"><img src=\"".$image["url"]."\" height=\"150px\" width=\"150px\"><span><img src=\"".$image["url"]."\"/><br/>".$movie->name."</span></a></td><td rowspan=\"6\"><img class=\"line\" width=\"2\" height=\"100%\"></td><td class=\"jralign\">Movie ID:</td><td>".$movie->id."</td></tr>" 
     ."<tr><td class=\"jralign\">Movie Link:</td><td><a href=\"".$movie->url."\">".$movie->url."</a></td></tr>" 
     ."<tr><td class=\"jralign\">Released:</td><td>".$movie->released."</td></tr>" 
     ."<tr><td class=\"jralign\">Classification:</td><td>".$movie->certification."</td></tr>" 
     ."<tr><td class=\"jralign\">Adult:</td><td>".$movie->adult."</td></tr>" 
     ."<tr><td class=\"jralign\" valign=\"top\">Overview:</td><td>".$movie->overview."</td></tr>" 
     ."</tfoot></table>" 
     ."</table><br/>"; 
    $i++; 
}

Answer 1

$images = $xml->xpath('/movies/movie/images/image'); 
$needed_image_url = ''; 
foreach($images as $image) { 
    $attributes = $image->attributes(); 
    if ($attributes['size'] == 'thumb') { 
     $needed_image_url = $attributes['url']; 
     break; 
    } 
} 

dies würde die Daumen Bild-URL zum Beispiel greifen.
