PHPDOM: how to edit style in HTML element

Question

I recently discovered PHPDom and found it very useful to manipulate HTML code. Unfortunately the documentation online is limited and there are no comprehensive PHPDom manuals that I am aware of. (There is no PHPdom tag in stockoverflow either!!)

This is the problem I am experiencing.

I would like to change the style an html tag, this is what I am using:

            $item = $dom->getElementById($name);
            $item->setAttribute('style', 'background-color:#FF0000;');
            $item = $dom->getElementById($name.'_error');
            $item->setAttribute('style', 'display:true;');

However the result of this code is that the styles defined in $name and name.'_error' are overwritten.

To fix the problem, I am looking for a PHPdom method, something like editAttribute, that allows to edit an attribute without overwriting the existing style attributes for that element.

Does anyone know how to fix this problem?

That does not help as . In fact, Linda needs to replace the href as a whole, which is not my case. — user1232551, Jul 28 '15 at 05:29
I found the solution: `$item->setAttribute('style', $item->getAttribute('style') . 'background-color:#FF0000;');`@Sundar — user1232551, Sep 29 '15 at 07:34

That would mean that you need to parse and edit the CSS properties in the attribute.

I implemented that in FluentDOM, actually. You can do something like:

$fd = FluentDOM($html, 'text/html');
$fd
  ->find('//a')
  ->css['text-decoration'] = 'none';
echo (string)$fd;

This logic is located in FluentDOM\Query\Css\Properties. You can use this object to edit a style property string.

$style = new FluentDOM\Query\Css\Properties($node->getAttribute('style'));
$style['background-color'] = '#FF0000';
$node->setAttribute('style', $style);
