创建和输出xml - creating and outputting xml

creating and outputting xml

本文关键字：xml 输出创建 | 更新日期: 2023-09-27

我有这样的代码:

$dom = new DOMDocument(); // new dom object
$dom->formatOutput = TRUE; //tidy the output
$root = $dom->appendChild($dom->createElement('PaymentNotificationResponse'));
$sxe = simplexml_import_dom( $dom ); 
        $xml_pay = $sxe->addChild('Payments');
        $paymnt = $xml_pay->addChild('Payment');
        $paymnt->addChild('PaymentLogId','123');
        $paymnt->addChild('Status', '0');
print_r($sxe);

应该输出如下内容:

<PaymentNotificationResponse>
 <Payments>
  <Payment>
   <PaymentLogId>123</PaymentLogId>
   <Status>0</Status>
  </Payment>
 </Payments>
</PaymentNotificationResponse>

但是我得到的是:

SimpleXMLElement Object ( [Payments] => SimpleXMLElement Object ( [Payment] => SimpleXMLElement Object ( [PaymentLogId] => 123 [Status] => 0 ) ) )

即使我使用

print_r($sxe->asXML())

它只给出

1230年

简简单单:

echo $sxe->asXML();

应该可以。

请注意，除非您有正确的标题，否则浏览器可能会将其读取为HTML。然后，您必须检查源代码以查看实际的XML。

要打印正确的输出，您应该打印$sxe->asXML()，但是如果您希望在浏览器上以XML格式显示输出，您还应该在php中打印标题:

header('Content-Type: application/xml; charset=utf-8')

对于示例来说，请检查下面的代码:

$dom = new DOMDocument(); // new dom object
$dom->formatOutput = TRUE; //tidy the output
$root = $dom->appendChild($dom->createElement('PaymentNotificationResponse'));
$sxe = simplexml_import_dom( $dom ); 
        $xml_pay = $sxe->addChild('Payments');
        $paymnt = $xml_pay->addChild('Payment');
        $paymnt->addChild('PaymentLogId','123');
        $paymnt->addChild('Status', '0');
print_r( header('Content-Type: application/xml; charset=utf-8') . $sxe->asXML());
