     </article> 

は私が記事のタグ内のpタグを取得したいです。

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


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

     $parag=array(); 

     foreach($paragraph as $para) 
     { 

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

     } 

をしかし、私は記事の内側のみのpタグを望む一方で、コードの上に私の記事のタグ内の全コンテンツを返します。私は使用しています。

私はnodeNameとchildNodesのようなプロパティを使用しようとしましたが、それは役に立ちませんでした。 私はウェブスクレイピングに素朴で解決策が見つからないため、以下のリンクを参照しました。tutorialとchildnodes

いくつかの例示的な解決策を教えてください。前もって感謝します。

私は要件上記の溶液は、XPathを使用して満たすことができました

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