Und ich möchte alle HTML-Dateien greifen, die in diesem Element befinden:

<content src="e9783641059446_cop01.html"/>

Derzeit ist es auf diese Weise versuche ich:

$ncx = simplexml_load_file($file); 
$items = $ncx->navMap->children(); 
foreach ($items as $it) { 
    echo $it->content['src']; 
}

Problem ist, dass die Inhaltsknoten nicht in der gleichen Tiefenstufe sind, wie Sie vielleicht bemerkt haben. Weiß jemand, wie man es repariert?

Ich kann Ihre Frage nicht genau verstehen. Möchten Sie alle Tags in 'e9783641059446_cop01.html' Datei erhalten? – Mohammad

Ich möchte alle Tags erhalten, um das Attribut src = "" zu erhalten. Die gesuchten Tags sehen immer so aus: – Curunir

Warum verwenden Sie nicht die Klasse 'DOMDocument'? – Mohammad

Das XML hat einen Namensraum. Versuchen Sie, mit

$ncx = simplexml_load_file('test.xml'); 
$ncx->registerXPathNamespace('x', 'http://www.daisy.org/z3986/2005/ncx/'); 
foreach ($ncx->xpath('//x:content/@src') as $src) { 
    echo $src, PHP_EOL; 
}

Ohne XPath:

$ncx = simplexml_load_file('test.xml', "SimpleXmlElement", 0, 'http://www.daisy.org/z3986/2005/ncx/', false); 
foreach ($ncx->navMap->navPoint as $np) { 
    echo $np->content->attributes()->src, PHP_EOL; 
}

Vielen Dank :)! – Curunir

der Inhalt Knoten nicht in der gleichen Tiefe Ebene sind

Sie können auch leicht DOMDocument-Klasse verwenden, um zu finden, Ziel-Tag. Beachten Sie, dass getElementsByTagName() Tag nach Name erhalten und getAttribute() Wert des Attributs erhalten.

$dom = DOMDocument::load($file); 
$contents = $dom->getElementsByTagName("content"); 
foreach($content as $content){ 
    echo $content->getAttribute("src"); 
}
