     </article> 

Ben makale etiketinin içine p etiketlerini almaya istiyorum.

$doc = new DOMDocument(); 
    libxml_use_internal_errors(true); 
    if($page) 
    { 
     $doc->loadHTML($page); 
    } 


$paragraph = $doc->getElementsByTagName('article'); 

     $parag=array(); 

     foreach($paragraph as $para) 
     { 

       if($para->nodeValue!="") 
       { 
        $parag[]=$para->nodeValue; 
       } 

     } 

Ama makalenin içindeki tek p etiketleri istiyorum oysa kod yukarıda bana makale etiketinin içinde tüm içeriği döndürür: Ben kullanıyorum.

nodeName ve childNodes gibi özellikleri kullanmayı denedim ancak yardımcı olmadı. Ben kazıma web safım ama çözüm tutorial ve

childnodes bana bazı örnek çözümü verin bulamadı gibi ben anlaşılması için bağlantıları takip atıfta bulunmuşlardır. şimdiden teşekkürler.

Answer 1

Ben gereksinimin üzerinde çözüm xpath ile sağlanabilir var

$xpath = new DOMXPath($doc); 
$news_paras = $xpath->query("//article//p"); 
$parag = array(); 
foreach ($news_paras as $news_para) 
{ $parag[]=$news_para->nodeValue; }
