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

case 1: inline css

<div id="id100" style="background:url(/mycar1.jpg)"></div>

case 2: css inside html page

<div id="id100"></div>

<style type="text/css">
#id100{
background:url(/mycar1.jpg);
}
</style>

case 3: separate css file

<div id="id100" style="background:url(/mycar1.jpg);"></div>

external.css

#id100{
background:url(/mycar1.jpg);
}

case 4: image inside img tag
