Je veux extraire chaque valeur comme les données de fabrication et les valeurs de toutes les années mentionnées dans cette ligne. Comment je vais à ce sujet?

J'ai trouvé quelque chose comme preg_match('#<tr><th>(.*)</th> <td><b>price</b></td></tr>#', $content, $match); mais cela n'obtient pas les valeurs que je veux.

** Don utiliser regex pour analyser HTML **, utilisez un [html dom parser à la place] (http://simplehtmldom.sourceforge.net/) –

Si je comprends bien vous la question que vous voulez quelque chose comme this à faire. Cela a été écrit par moi, donc si vous avez besoin de clarifications j'aimerais aider.

bravo!

Vous pouvez utiliser des bibliothèques comme PHP Simple HTML DOM Parser pour extraire des données à partir de HTML/XHTML.
http://simplehtmldom.sourceforge.net/manual.htm

Un exemple:

$pageDom = str_get_html($rawHtmlData); 
foreach($pageDom->find('td') as $tblElem) 
{ 
    if(FALSE !== stristr($tblElem->innertext, 'Manufacturing expenses')) 
    { 
     // Do stuff 
    } 
}

Suggestions d'alternatives tierces à [SimpleHtmlDom] (http://simplehtmldom.sourceforge.net/) qui utilisent réellement [DOM ] (http://php.net/manual/en/book.dom.php) au lieu de String Parsing: [phpQuery] (http://code.google.com/p/phpquery/), [Zend_Dom] (http : //framework.zend.com/manual/en/zend.dom.html), [QueryPath] (http://querypath.org/) et [FluentDom] (http://www.fluentdom.org). – Gordon
