使用PHP获取和设置内联样式

Question

Is there a way to get and set inline styles of DOM elements inside an HTML fragment with PHP? Example:

<div style="background-color:black"></div>

I need to get whether the background-color is black and if it is, change it to white . (This is an example and not the actual goal)

I tried phpQuery, but it lacks the .css() method, while the branch that implements it doesn't seem to work (at least for me).

Basically, what I need is a port of jQuery's .css() method to PHP.

Per Ryan P's good suggestion above, the PHP DOM functions may help you out. Something like this might do what you want with that particular example.

$my_url = 'index.php';
$dom = new DOMDocument; 
$dom->loadHTMLfile($my_url);

$divs = $dom->getElementsByTagName('div');
foreach ($divs as $div) {
    $div_style = $div->getAttribute('style');
    if ($div_style && $div_style=='background-color:black;') {
    $div->setAttribute('style','background-color:white;');
    }
}

echo $dom->saveHTML();
