Napisałem sobie taką oto klasę:

[PHP] pobierz, plaintext 

Po wywołaniu tej klasy, przypisuję do każdej zmiennej szukanej wartości - zdjęcie, tytuł i treść.

Niestety tytuł zawiera również ciąg URL obrazka, natomiast tekst zawiera dodatkowo obrazek oraz tytuł. Gdzie robię błąd? Jak to oddzielić?

Jednocześnie proszę o sugestię co mogę poprawić w samej klasie.

Działa gdy zmieniłem na:

[PHP] pobierz, plaintext 
 
public function getData($noHTML = false, $removeAttribute = false){
 
        $data_after1 = '';
        foreach ($this->data as $dataNodes){
 
            if($removeAttribute === true) {
                $dataNodes->removeAttribute('style');
                $dataNodes->removeAttribute('class');
                $dataNodes->removeAttribute('id');
            }
 
            if($noHTML === true){
                $data_after1 .= $dataNodes->nodeValue;
            }else{
                $data_after1 .= $dataNodes->ownerDocument->saveHTML($dataNodes);
            }
 
        }
 
        return $data_after1;
    }
