How should parse with PHP (simple html dom/etc..) background and other images of webpage? case 1: inline css

Solution 1:

For Case 1:

// Create DOM from URL or file $html = file_get_html('http://www.google.com/');

// Get the style attribute for the item$style = $html->getElementById("id100")->getAttribute('style');

// $style = background:url(/mycar1.jpg)// You would now need to put it into a css parser or do some regular expression magic to get the values you need.

For Case 2/3:

// Create DOM from URL or file$html = file_get_html('http://www.google.com/');

// Get the Style element$style = $html->find('head',0)->find('style');

// $style now contains an array of style elements within the head. You will need to work out using attribute selectors what whether an element has a src attribute, if it does download the external css file and parse (using a css parser), if it doesnt then pass the innertext to the css parser.

Solution 2:

To extract <img> from the page you can try something like:

$doc = new DOMDocument(); 
$doc->loadHTML("<html><body>Foo<br><img src=\"bar.jpg\" title=\"Foo bar\" alt=\"alt\"></body></html>"); 
$xml = simplexml_import_dom($doc);
$images = $xml->xpath('//img'); 
foreach ($imagesas$img) 
    echo$img['src'] . ' ' . $img['alt'] . ' ' . $img['title'];

See doc for DOMDocument for more details.
