PHP returnネストされたXML

Question

私は、以下のコードに従ってファイルからXMLを取得しています。しかし、XMLが".$image["url"]."の時点で深くなると、画像の1つを取得しようとしていますが、動作していません。私はまた、XML（以下のXML）のSIZE変数によって複数のタグがあるので、画像を検索する必要があります。

私はすでに$ xml-> xpathを上位のコンテナに定義した後でこれを定義しますか？

$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++; 
} 

XML検索中です。

更新された機能：画像が表示されません。

 $searchurl = "movies.xml"; 
     $xml = simplexml_load_file($searchurl);

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; 
    } 
} 

これは、例えば、親指の画像のURLをつかむでしょう。
