// --- How to get HTML elements?

// Create DOM from string

// Find all images

	echo $element->src . "\n";

// Find all links

	echo $element->href . "\n";

// --- How to modify HTML elements?

// Create DOM from string
$dom = CDom::fromString('<div id="hello">Hello</div><div id="world">World</div>');

// Add class to the second div (first last child)
$dom->find('div:nth-last-child(1)')->class = 'bar';

// Change text of first div
$dom->find('div[id=hello]')->text('foo');

echo $dom . "\n"; // Output: <div id="hello">foo</div><div id="world" class="bar">World</div>



// --- Extract contents from HTML
