PHP возвращает вложенный XML

Question

Я извлекаю XML из файла в соответствии с кодом ниже.Однако, когда XML становится глубже в точке ".$image["url"].", я пытаюсь получить одно из изображений, но оно не работает.Мне также нужно было бы искать изображения, так как в XML есть переменная SIZE для нескольких тегов (XML ниже).

как вы определяете это после того, как я уже определил $ xml-> xpath для более высокогоКонтейнер?

$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;
    }
}

это, например, захватит URL изображения большого пальца.
