xPath selector does not work correctly

I have a function to grab images src attribute in a section tag. but it give me images src out of this specified section tag (selected by class). 

$doc = new DOMDocument();
@$doc->loadHTMLFile('http://www.akairan.com/health/bimari-behdasht/news201691911413397586.html');

$finder = new DomXPath($doc);
$imgNodes = $finder->query('//article[@class="contentpaneopen_text"]//img/@src');

$images = array();
foreach($imgNodes as $node) {
    echo $node->nodeValue . "<br />";
}

The result is:

But it should return just first link not the others.

Solution

  • Since there are more than one <img> children inside <article class="contentpaneopen_text">, it's normal that you get more than one result.

    Your xpath needs to be more precise. We can see that the one you want to match should also have a parent <a> and should have a title attribute.

    try with:

    //article[@class="contentpaneopen_text"]//a/img[@title!='']/@src
