Question

这是一个简单的问题，但是我无法获得$results = 'http://www.daikyo.co.jp/KOBETSU/MF081014/gaiyo_chg.html?_ga=2.231780890.465420601.1540169716-1978642370.1538226055&_bdld=HYzpv.moBqKE6'; $html = file_get_contents($results); $DOMParser = new \DOMDocument(); $DOMParser->loadHTML($html); $changeForMyDB = [ 'region' => '関西', 'link' => json_encode($results), 'building_name' => '', 'price' => '', 'old_price' => '', 'extend' => '', 'address' => '', 'total_house' => '', 'rooms' => '', 'cons_finish' => '', 'entry' => '', 'balcony' => '', 'company_name' => '', 'list_from' => 'daikyo' ]; $changeForMyDB['building_name'] = trim($DOMParser->getElementsByTagName('h1')->nodeValue);标签的文本。 DOMparser返回此错误。

def unique(s):
    return len(s) == len(set(s))

h1中的文本不返回？

Answer 1

您可以像这样使用它。

$Tags = $DOMParser->getElementsByTagName('h1');
                foreach ($Tags as $h1tag) {
                        $changeForMyDB['building_name'] = trim($h1tag->nodeValue);
                }

会解决的。

DOMparser返回此错误Undefined属性：DOMNodeList :: $ nodeValue
