Question

我正在尝试使用PHP（XML）在父元素中添加多个元素：

这就是我想要实现的目标：

<ns0:XmlInterchange xmlns:ns0="http://www.edi.com.au/EnterpriseService/" xmlns:ext="http://esb.dsv.com/ExtensionFunctions">
  <ns0:InterchangeInfo>
     <ns0:Date>2017-07-20 13:41:48</ns0:Date>
     <ns0:XmlType>Verbose</ns0:XmlType>
     <ns0:Source>
        <ns0:EnterpriseCode>Company</ns0:Enterprisecode>
     </ns0:Source>
 </ns0:InterchangeInfo>
</ns0:XmlInterchange>

我有以下PHP代码：

$xml = new DOMDocument('1.0', 'UTF-8');
$xml->formatOutput = true;

$interchange = $xml->createElementNS('ns0', 'ns0:XmlInterchange');
$interchange->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:ns0', 'http://www.edi.com.au/EnterpriseService/');
$interchange->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:ext', 'http://esb.dsv.com/ExtensionFunctions');
$xml->appendChild($interchange); //Add above attributes to our element. <!Xmlinterchange->

$item = $xml->createElement('ns0:InterchangeInfo');
$item->appendChild($xml->createElement('ns0:Date',$invoice_date));
$item->appendChild($xml->createElement('ns0:XmlType','Verbose'));
$item = $xml->createElement('ns0:Source');
$item->appendChild($xml->createElement('ns0:EnterpriseCode','Company'));
$interchange->appendChild($item);
unset($item); //Reset $item, so we can use the variable again.

但是，上面的输出：

<ns0:XmlInterchange xmlns:ns0="http://www.edi.com.au/EnterpriseService/" xmlns:ext="http://esb.dsv.com/ExtensionFunctions">
  <ns0:Source>
    <ns0:EnterpriseCode>Company</ns0:EnterpriseCode>
  </ns0:Source>
</ns0:XmlInterchange>

我希望能够将<ns0:Source>元素放在<ns0:InterChangeInfo>元素中，但与其他元素一起使用。

Answer 1

您必须将<ns0:Source>附加到<ns0:InterchangeInfo>。之后，将<ns0:InterchangeInfo>附加到<ns0:XmlInterchange>。

请记住：->appendChild()表示不附加但附加在内部。所以$a->appendChild($b);表示你将b附加到。

中

尝试：

$xml = new DOMDocument('1.0', 'UTF-8');
$xml->formatOutput = true;

$interchange = $xml->createElementNS('ns0', 'ns0:XmlInterchange');
$interchange->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:ns0', 'http://www.edi.com.au/EnterpriseService/');
$interchange->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns:ext', 'http://esb.dsv.com/ExtensionFunctions');

$item = $xml->createElement('ns0:InterchangeInfo');
$item->appendChild($xml->createElement('ns0:Date',$invoice_date));
$item->appendChild($xml->createElement('ns0:XmlType','Verbose'));

$source = $xml->createElement('ns0:Source');
$source->appendChild($xml->createElement('ns0:EnterpriseCode','Company'));
$item->appendChild($source);

$interchange->appendChild($item);

$xml->appendChild($interchange);
