Question

我正在使用以下代码......

//定义我们希望写入的文件名以及我们希望从

下载的网址

    $filename = 'capital_one.xml';
    $url = "http://feeds.perfb.com/index.php/download?OEMAIL=chirag_gir@visitwembley.co.uk&PX=e90daba5ee2c6fd4d0c344fd61911f33&DISPLAYFORMAT=HEAD&REVERSEMAPXML=yes&PRODUCTDB_ID=294";



 //this creates the file "feed download".xml and takes he contents from the URL and stores them into the file
file_put_contents($filename,file_get_contents($url));

//create instance of XMLReader
    $xmlReader = new XMLReader();

//read in xml file
$xmlReader->open($filename);

//loop to read in data
while($xmlReader->read())
{
         //this initialises the xml parser
         $dom = new DOMDocument();
         $domNode = $xmlReader->expand();
         $element = $dom->appendChild($domNode);
         $domString = utf8_encode($dom->saveXML($element));
         $product = new SimpleXMLElement($domString);

         //read in data
         echo $product_code = $product->product_code;


}

我收到了以下错误

捕获致命错误：传递给DOMNode :: appendChild（）的参数1必须是DOMNode的实例

你能帮我吗？

如果expand()未返回DOMNode，则会发生错误，而是返回FALSE。
