Question

我有一个运行良好的PHP代码，但是运行不正常。 F.Y.I：：它正在运行一个从表单收集提交的数据的功能。（此处未包含代码段，因为可以）。我需要在“ Dados”中包含2个字段：名称和电子邮件，但是只记录了 email 。

我该怎么办？有任何线索吗？

我的实际PHP代码：

function my_generate_xml($posted_data) 

$domDocument = new DOMDocument('1.0', 'ISO-8859-1');
$domDocument->formatOutput = true;

// build maximizer xml file
$xml_root = $domDocument->createElement('moduledata');

$xmlEntity = $domDocument->createElement('entity');
$xmlEntityTN = $domDocument->createAttribute('tablename');
$xmlEntityTN->value = 'Ent';
$xmlEntityFN = $domDocument->createAttribute('formatname');
$xmlEntityFN->value = 'Curriculum';
$xmlEntity->appendChild($xmlEntityTN);
$xmlEntity->appendChild($xmlEntityFN);

$xmlDefine = $domDocument->createElement('define');
$xmlDefine->nodeValue = $posted_data['nome'];
$xmlDefineN = $domDocument->createAttribute('name');
$xmlDefineN->value = 'ParamNome';
$xmlDefine->appendChild($xmlDefineN);
$xmlEntity->appendChild($xmlDefine);

$xmlSiga = $domDocument->createElement('SigaFiles');
$xmlSigaDN = $domDocument->createAttribute('Text');
$xmlSigaDN->value = 'SQG';
$xmlSiga->appendChild($xmlSigaDN);

// create node for current dados
$xml_dados = $domDocument->createElement('Dados');
$domElement = $domDocument->createElement('attribute',$posted_data['nome']);
$domElement = $domDocument->createElement('attribute',$posted_data['email']);
$domAttribute = $domDocument->createAttribute('domainname');

// Value for the created attribute
$domAttribute->value = 'Nome';
$domAttribute->value = 'Email';

$domElement->appendChild($domAttribute);
$xml_dados->appendChild($domElement);
$xmlSiga->appendChild($xml_dados);
$xmlEntity->appendChild($xmlSiga);
$xml_root->appendChild($xmlEntity);
$domDocument->appendChild($xml_root);

所需的XML输出格式：

<?xml version="1.0" encoding="ISO-8859-1" ?>
<moduledata>
  <entity tablename="Ent" formatname="Curriculum">
   <define name="ParamNome">Thomas Edison</define>
   <SigaFiles Text="SQG">
    <Dados>
      <attribute domainname="Nome">Thomas Edison</attribute>
      <attribute domainname="Email">thomas.edison@gmail.com</attribute>
    </Dados>
   </SigaFiles>
  </entity>
 </moduledata>

实际的XML输出格式：

<?xml version="1.0" encoding="ISO-8859-1"?>
<moduledata>
  <entity tablename="Ent" formatname="Curriculum">
    <define name="ParamNome">Thomas Edison</define>
    <SigaFiles Text="SQG">
      <Dados>
        <attribute domainname="Email">thomas.edison@gmail.com</attribute>
      </Dados>
    </SigaFiles>
  </entity>
</moduledata>

实际XML输出格式：（已更新）

<?xml version="1.0" encoding="ISO-8859-1"?>
<moduledata>
  <entity tablename="Ent" formatname="Curriculum">
    <define name="Thomas Edison">nome</define>
    <SigaFiles Text="SQG">
      <Dados>
        <attribute domainname="Nome">Thomas Edison</attribute>
        <attribute domainname="Email">thomas.edison@gmail.com</attribute>
      </Dados>
    </SigaFiles>
  </entity>
</moduledata>

PHP代码（已更新）

 <?php

function my_generate_xml($posted_data) 
{
    $domDocument = new DOMDocument('1.0', 'ISO-8859-1');
	$domDocument->formatOutput = true;

	// build maximizer xml file
	$xml_root = $domDocument->createElement('moduledata');

	$xmlEntity->appendChild($xmlEntityTN);
	$xmlEntity->appendChild($xmlEntityFN);

	$xmlDefine = $domDocument->createElement('define');
	$xmlDefine->nodeValue = $posted_data['nome'];
	$xmlDefineN = $domDocument->createAttribute('name');
	$xmlDefineN->value = 'ParamNome';
	$xmlDefine->appendChild($xmlDefineN);
	$xmlEntity->appendChild($xmlDefine);

	// create node for current dados
	$xml_dados = $xmlSiga->appendChild($domDocument->createElement('Dados'));

	$domElement = $xml_dados->appendChild($domDocument->createElement('attribute'));
        $domElement->appendChild($domDocument->createTextNode($posted_data['nome']));
	$domElement->setAttribute('domainname', 'Nome');

	$domElement = $xml_dados->appendChild($domDocument->createElement('attribute'));
	$domElement->appendChild($domDocument->createTextNode($posted_data['email']));
	$domElement->setAttribute('domainname', 'Email');
	
	$domDocument->appendChild($domElement);
	$xmlSiga->appendChild($domDocument);
	$xmlEntity->appendChild($xmlSiga);
	$xml_root->appendChild($xmlEntity);
	$domDocument->appendChild($xml_root);

    // save it as a file for further processing
    $content = chunk_split(base64_encode($domDocument->saveXML()));

    $uploads = wp_upload_dir();     

    $domDocument->save($uploads['basedir'].'/prorh/'.(int)microtime(true).'.xml');
}

?>

请考虑在创建例程后重新组织例程并追加元素，不要在最后保存所有appendChild调用。由于重复使用相同的变量名，因此将所有组件（元素，属性，值）保持在一起。回忆XML是从根开始生长的树结构：

// build maximizer xml file
$domDocument = new DOMDocument('1.0', 'ISO-8859-1');
$domDocument->formatOutput = true;

// moduledata root element
$xml_root = $domDocument->createElement('moduledata');
$domDocument->appendChild($xml_root);                          

// entity element
$xmlEntity = $domDocument->createElement('entity');
$xml_root->appendChild($xmlEntity);    
$xmlEntityTN = $domDocument->createAttribute('tablename');
$xmlEntityTN->value = 'Ent';
$xmlEntityFN = $domDocument->createAttribute('formatname');
$xmlEntityFN->value = 'Curriculum';
$xmlEntity->appendChild($xmlEntityTN);
$xmlEntity->appendChild($xmlEntityFN);

// define element
$xmlDefine = $domDocument->createElement('define');
$xmlEntity->appendChild($xmlDefine);   
$xmlDefine->nodeValue = $posted_data['nome'];
$xmlDefineN = $domDocument->createAttribute('name');
$xmlDefineN->value = 'ParamNome';
$xmlDefine->appendChild($xmlDefineN);

// SigaFiles element
$xmlSiga = $domDocument->createElement('SigaFiles');
$xmlEntity->appendChild($xmlSiga);  
$xmlSigaDN = $domDocument->createAttribute('Text');
$xmlSigaDN->value = 'SQG';
$xmlSiga->appendChild($xmlSigaDN);   

// dados element
$xml_dados = $domDocument->createElement('Dados');
$xmlSiga->appendChild($xml_dados);   

   // attribute child nodes
   $domElement = $domDocument->createElement('attribute', $posted_data['nome']);
   $domAttribute = $domDocument->createAttribute('domainname');
   $domAttribute->value = 'Nome';
   $domElement->appendChild($domAttribute);
   $xml_dados->appendChild($domElement);                         

   $domElement = $domDocument->createElement('attribute', $posted_data['email']);
   $domAttribute = $domDocument->createAttribute('domainname');
   $domAttribute->value = 'Email';
   $domElement->appendChild($domAttribute);
   $xml_dados->appendChild($domElement);                        

// OUTPUT TREE TO STRING
header("Content-type: text/xml");
echo $domDocument->saveXML();

您覆盖$domElement变量而不附加节点。

// create node for current dados
$xml_dados = $domDocument->createElement('Dados');
$domElement = $domDocument->createElement('attribute',$posted_data['nome']);
$domElement = $domDocument->createElement('attribute',$posted_data['email']);
$domAttribute = $domDocument->createAttribute('domainname');

我建议将create*个调用嵌套在appendChild()个调用中。

// create node for current dados
$xml_dados = $xmlSiga->appendChild($domDocument->createElement('Dados'));

$domElement = $xml_dados->appendChild($domDocument->createElement('attribute'));
$domElement->appendChild($domDocument->createTextNode($posted_data['nome']));
$domElement->setAttribute('domainname', 'Nome');

$domElement = $xml_dados->appendChild($domDocument->createElement('attribute'));
$domElement->appendChild($domDocument->createTextNode($posted_data['email']));
$domElement->setAttribute('domainname', 'Email');

您无需将属性创建为节点，DOMElement::setAttribute()可以正常工作。但是您应该创建文本内容作为节点。 DOMDocument :: createElement（）的第二个参数已损坏，并且仅转义了一些特殊字符。

如何在同一属性-XML（PHP代码）中添加多个元素？
