php - Using SimpleHtmlDom, how to remove and replace a specific attribute

Question

I'm currently using this HTML DOM PARSER using php : http://simplehtmldom.sourceforge.net/

I'm confused on how to remove and replace the selected attribute href="style.css", I want to replace the link with "index/style.css", should I insert only the

index/

or replace the whole attribute from the whole html code?

This should do it:

$doc = str_get_html($code);
foreach ($doc->find('a[href]') as $a) {
    $href = $a->href;
    if (/* $href begins with a relative URL path */) {
        $a->href = 'index/'.$href;
    }

}
$code = (string) $doc;

You could also use PHP’s native DOM library:

$doc = new DOMDocument();
$doc->loadHTML($code);
$xpath = new DOMXpath($doc);
foreach ($xpath->query('//a[@href]') as $a) {
    $href = $a->getAttribute('href');
    if (/* $href begins with a relative URL path */) {
        $a->setAttribute('href', 'index/'.$href);
    }
}
$code = $doc->saveHTML();
