如何使用domdocument php只调用一次UL类

Question

I am using PHP Domdocument to load my html. In my HTML, I have class="smalllist" two times. But, I need to load the first class elements.

Now, My PHP Code is

    $d = new DOMDocument();
    $d->validateOnParse = true;
    @$d->loadHTML($html);
    $xpath = new DOMXPath($d);
    $table = $xpath->query('//ul[@class="smalllist"]');
    foreach ($table as $row) {
       echo $row->getElementsByTagName('a')->item(0)->nodeValue."-";
       echo $row->getElementsByTagName('a')->item(1)->nodeValue."
";

    }

which loads both the classes. But, I need to load only one class with that name. Please help me in this. Thanks in advance.

This is my final code:

        $d = new DOMDocument();
        $d->validateOnParse = true;
        @$d->loadHTML($html);
        $xpath = new DOMXPath($d);
        $table = $xpath->query('//ul[@class="smalllist"]');
        $count = 0;
        foreach($table->item(0)->getElementsByTagName('a') as $anchor){
           $data[$k][$arr1[$count]] = $anchor->nodeValue;
           if( ++$count > 1 ) {
              break;
           }
        }

Working fine.
