Regular expression to find all “src” attribute of HTML “img” element only folder in PHP

Question

I have a string, inside of that I have an image:

\"
balbalba


        

Answer 1

You could do this with a parser and a simple regex to check the attribute starts with required directory...

$string = '
balbalba
balbalba
balbalba
';
$doc = new DOMDocument();
$doc->loadHTML($string);
$images = $doc->getElementsByTagName('img');
foreach ($images as $image) {
    if(preg_match('~^img/programacao/~', $image->getAttribute('src'))) {
        echo $image->getAttribute('src') . "\n";
    }
}

Output:

img/programacao/51.jpg
img/programacao/46.jpg
