PHP - 无限循环的问题

Question

I have no clue what I am doing wrong. EVERY time it goes through it just keeps looping and pulling all of the cities listed in the same row and placing them with the state, then when it goes to the next state it starts at the correct place, but still keeps going. I've tried for 4 hours I just can't figure it out.

$url = 'http://www.craigslist.org/about/sites';
$output = file_get_contents($url); 
$doc = new DOMDocument();

libxml_use_internal_errors(true); //Supress Warnings for HTML5 conversion issue
$doc->loadHTML($output);
libxml_use_internal_errors(false); //Start Showing Errors

$xpath = new DOMXpath($doc);    

foreach ($xpath->query('//h1') as $e) {
    $country = $e->nodeValue;
    $list = array();
    foreach ($xpath->query('./following-sibling::div[@class="colmask"]', $e) as $li) {

        foreach ($xpath->query('//div/h4', $e) as $div) {
            $state = $div->nodeValue;


            foreach ($xpath->query('./following-sibling::ul/li', $div) as $div2) {                      

                $href =  $div2->getAttribute("href");
                $text = trim(preg_replace("/[
]+/", " ", $div2->nodeValue));
                echo 'Country: ' . $country . ' State: ' . $state . ' CITY: text['. $text . '] href[' . $href . '] <br/><br/><br/>';


            }


        }

    }
}

Had someone named DuffyDake answer my question. Here is the answer..

foreach ($xpath->query('./following-sibling::ul[1]/li', $div) as $div2) {                      

                $href =  $div2->getAttribute("href");
                $text = trim(preg_replace("/[
]+/", " ", $div2->nodeValue));
                echo 'Country: ' . $country . ' State: ' . $state . ' CITY: text['. $text . '] href[' . $href . '] <br/><br/><br/>';


            }

The missing piece is the [1] to reference to the first UL found and not anything past that
