我已经工作了几个小时试图让输出XML与我给出的规范相匹配,而我却找不到合适的代码来完成它。我正在使用DOMDocument,因为我读到它比SimpleXML更灵活。
期望的最终结果:
<?xml version="1.0" encoding="UTF-8"?>
<retail xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<partnerid>XYZ</partnerid>
<customer xmlns:a="http://schemas.datacontract.org/2004/07/DealerTrack.DataContracts.CreditApp">
<a:info>
<a:FirstName>Bob</a:FirstName>
<a:LastName>Hoskins</a:LastName>
</a:info>
</customer>
<refnum i:nil="true"/>
</retail>
...以及我用来实现的代码(缩写):
$node = new DOMDocument('1.0', 'UTF-8');
$root = $node->createElementNS( 'http://www.w3.org/2001/XMLSchema-instance', 'retail' );
$root->setAttributeNS('http://www.w3.org/2001/XMLSchema-instance', 'xmlns:i', 'test');
$capp = $node->appendChild($root);
$cnode = $node->createElement("partnerid", 'XYZ');
$capp->appendChild($cnode);
......这不是我想要的东西。我已经尝试了至少十几个createElementNS,setAttributeNS的组合,查看了几个例子,找不到任何让我接近我所追求的东西。我已经可以在SimpleXML中执行此操作,但我想了解正在发生的事情以及如何在此实例中使用DOM。

除了alex blex回答:对于根元素(仅适用于它),您还可以简单地创建一个属性命名空间,而不将其附加到根元素。
$dom = new DOMDocument('1.0', 'UTF-8');
$namespaceURIs = [
'xmlns' => 'http://www.w3.org/2000/xmlns/',
'i' => 'http://www.w3.org/2001/XMLSchema-instance',
'a' => 'http://schemas.datacontract.org/2004/07/DealerTrack.DataContracts.CreditApp'
];
$root = $dom->createElement('retail');
$dom->appendChild($root);
$dom->createAttributeNS($namespaceURIs['i'], 'i:attr');
// note that you don't have to append it: `CreateAttributeNS` defines a namespace for
// the entire document and will be automatically attached to the root element.
$root->appendChild($dom->createElement('partnerid', 'XYZ'));
$customer = $dom->createElement('customer');
$customer->setAttributeNS($namespaceURIs['xmlns'], 'xmlns:a', $namespaceURIs['a']);
// `setAttributeNS` allows to define local namespaces, that's why it needs to be
// attached to a particular element.
$root->appendChild($customer);
$info = $dom->createElementNS($namespaceURIs['a'], 'a:info');
$customer->appendChild($info);
// etc.
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
echo $dom->saveXML();
另外,随意测试其他php XML内置API:XMLWriter

如果我理解问题是retail
元素。
$node = new DOMDocument('1.0', 'UTF-8');
$root = $node->createElement('retail' );
$root->setAttributeNS(
'http://www.w3.org/2000/xmlns/',
'xmlns:i',
'http://www.w3.org/2001/XMLSchema-instance'
);
$capp = $node->appendChild($root);
$cnode = $node->createElement("partnerid", 'XYZ');
$capp->appendChild($cnode);
应该给你预期的输出。 http://php.net/manual/en/domdocument.createelementns.php
