        <li class="anker" id="artists-A"></li>
        <li class="first">
            <a href="www.test1.html" title="Test1">
            <span>
            <img src="https://www.test1.de/img/test1.jpg" alt="Test1" />
            <span>Test1</span>
            </span>
            </a>
        </li>
        <li>
            <a href="www.test2.html" title="Test2">
            <span>
            <img src="https://www.test2.de/img/test2.jpg" alt="Test2" />
            <span>Test2</span>
            </span>
            </a>
        </li>
        <li class="first">
            <a href="www.test3.html" title="Test3">
            <span>
            <img src="https://www.test1.de/img/test3.jpg" alt="Test3" />
            <span>Test3</span>
            </span>
            </a>
        </li>
      </ul> 
</div>

Need to get a href value,img src and span ie Title . I am parsing this using domDocument but not getting exact result.

Code:

$doc = new DomDocument; 
$doc->validateOnParse = true; 
$doc->loadHtml(file_get_contents($url)); 
$xpath = new DOMXPath($doc);
$nodes = $xpath->query('//[@id="testid"]/ul/li');

Here we are using DOMDocument. For now i am gathering a's href and img's src, you can add further more tags you want.

Try this code snippet here

$domDocument = new DOMDocument();
$domDocument->loadHTML($string);

$domXPath = new DOMXPath($domDocument);
$results = $domXPath->query("//div[@id='testid']");//querying div with id="testid"
$results = $domXPath->query("//a|//img",$results->item(0));//querying resultant div for a and img
$data=array();
foreach($results as $result){
    if($result->tagName=="a")//checking for anchor tags
    {
        $data["a"][]=array(
            "href"=>$result->getAttribute("href"),
            "title"=>$result->getAttribute("title")
        );
    }
    elseif($result->tagName=="img")//checking for image tags
    {
        $data["img"][]=$result->getAttribute("src");
    }
}
print_r($data);
