Selecting a css class with xpath

I am trying to extract the source for all images inside a html like this

    <li class="carousel_item">
    <img src="http://www.xxxx.com/1fc1c1c2db5852e08ffcff38.jpg" 
                        width="200" 
                        height="200" 

                        style="margin-bottom:1px" 
                        class="image_error" /> 
                    <span class="image_error" title="jpg"></span> 
                    <span class="image_error" title="2.jpg"></span> 
                </li> 

When I use the following commands I get all images in the document

   $nodelist = $xpath->query( "//img/@src" );
   foreach ($nodelist as $n){
    echo  $n->nodeValue."<br>";
 }

but I want just the items listed in the class=”carousel_item”

Is this possible?

Sure, just include the <li> and its class attribute in the query. You just need to change the xpath string to:

$nodelist = $xpath->query( "//li[@class='carousel_item']/img/@src" );
