Regex to change format of all img src attributes

Hi,

I want to replace the image path in my content db field.

I have the following

preg_replace("/src='(?:[^'\/]*\/)*([^']+)'/g","src='newPath/$2'",$content);

which is working fine for

src="/path/path/image.jpg"

BUT fails ON

src="http://www.mydomain.com/path/path/image.jpg"

Any help to bypass this problem?

Don't use regular expressions for this. Use a HTML parser like Simple HTML DOM.

$html = file_get_html('http://www.example.com/sourcepage.html');

foreach($html->find('img') as $element)  
 {      
    $new_src = "Do stuff with new src here"; 
    $element->src = $new_src;
 }

 echo $html; // Output new code
