如何从冰山中提取重量

Question

我正在尝试通过ean产品创建一个从Icecat目录中提取，重量或高度....的功能。

你对synthax有什么想法吗？

我很少丢失所有数据。

谢谢。

   public function getSearchProductEanXML() {
      $ean = $this->ean;
      $language = $this->lang;
      if($this->ean == null) {
        return 0;
      }

      $url = 'http://data.icecat.biz/xml_s3/xml_server3.cgi?ean_upc=' . $ean . ';lang=' . $language . ';output=productxml';
      $context = stream_context_create(array('http' => array( 'header'  => "Authorization: Basic " . base64_encode($this->username . ":" . $this->password) )));

      $data = file_get_contents($url, false, $context);

      $xml = new SimpleXMLElement($data);

      return $xml;
    }

// function to extract weight
      public function getProductWeight() {
        $xml = $this->getSearchProductEanXML();
        $product_pdf_weight = $xml->xpath("//ProductFeature");

        foreach($product_pdf_weight as $item) {
          $weight = $item->attributes();
          var_dump($weight);
          var_dump('<hr>');
    //      $WeightItem = new SimpleXMLElement($item->asXML());
    //      $weight = $WeightItem->xpath("//Name");
    //      var_dump($weight);
    //      $weight = $weight['Value'];
        }
        exit;
        return $weight;
      }
