Bonjour, bonjour…

Sur mon site perso, je collecte quelques flux RSS/Atom, grâce à la function ‘simple\_load\_xml’ de PHP, et entres autres le flux RSS de mon compte github.  
Hors, je me rend compte que les urls renseignées dans l’attribut href sont de type relatif, et non absolu… il manque tout simplement le scheme et le nom de domaine de github avant… (tel que : [https://github.com](https://github.com))

Le contenu est celui de $item-\>content, et peut être de cet acabit :

```auto
<div class="issues_comment"><div class="body">
<!-- issue_comment -->
<div class="d-flex border-bottom border-gray-light py-3">
    <span class="mr-3">

        <p>But, for OpenBSD 6.2:

    </div>
  </div>
</div>
</div></div>

```

Bref, quel est le “meilleur” moyen, s’il en est, de parcourir le code html retourné par $item-\>content, pour ajouter le sheme + le nom de domaine dans l’attribut href de l’élément a, s’il n’existe pas dans cet attribut ?

Dsl, mais insatifaisant…  
Le traitement est purement en PHP, je ne vais pas rajouter une surcouche…

Je pense me diriger vers la manipulation du DOM, mais j’hésite - parce que je ne maîtrise pas ce genre de pratique 😛

Bon, je l’ai résolu ainsi - semble-t-il :

```auto
$dom = new DOMDocument();
                @$dom->loadHTML($item->content);
                    
                foreach ($dom->getElementsByTagName('a') as $a) {
                    
                    $urls = parse_url($a->getAttribute('href'));
                    if(array_key_exists('scheme', $urls) == False) $urls['scheme'] = 'https';
                    if(array_key_exists('host', $urls) == False) $urls['host'] = $domain;
                        
                    $a->setAttribute('href', build_url($urls));
                        
                }
                unset($a);

            $content = $dom->saveHTML();

```

Et la function buil\_urls() est :

```auto
function build_url(array $parts) {
    return (isset($parts['scheme']) ? "{$parts['scheme']}:" : '') . 
        ((isset($parts['user']) || isset($parts['host'])) ? '//' : '') . 
        (isset($parts['user']) ? "{$parts['user']}" : '') . 
        (isset($parts['pass']) ? ":{$parts['pass']}" : '') . 
        (isset($parts['user']) ? '@' : '') . 
        (isset($parts['host']) ? "{$parts['host']}" : '') . 
        (isset($parts['port']) ? ":{$parts['port']}" : '') . 
        (isset($parts['path']) ? "{$parts['path']}" : '') . 
        (isset($parts['query']) ? "?{$parts['query']}" : '') . 
        (isset($parts['fragment']) ? "#{$parts['fragment']}" : '');
}

```

Bien sûr, j’appelle non plus `$item->content` pour afficher le contenu modifié, mais bel et bien `$content` 😉

Je note la méthode ça pourrait me servir plus tard 😉
