如何通过dom和php显示数据

Question

这是我的php代码：执行这个php后，数据显示在这个文件的底部。我希望它只添加一个人员元素。

$name = $_POST['sName'];
$ic = $_POST['sIC'];
$email = $_POST['sEmail'];
$address = $_POST['sAddress'];
$nophone = $_POST['sPhone'];

$dom = new DOMDocument();
$dom->formatOutput = true;
$dom->preserveWhiteSpace = false;


//loading the existing XML file
$dom->load('phone_XML.xml');

在同一文件 php 中写入新的 xml 节点：

$phone = $dom->documentElement;
$staff = $dom->documentElement;
// appendChild() can be combined with the create*()
//$staff = $phone->appendChild($dom->createElement("staff"));

// you missed the `s` element node
$s = $staff->appendChild($dom->createElement('s'));
$s->setAttribute('id', 'S002Doe');

$s
->appendChild($dom->createElement('sName'))
->appendChild($dom->createTextNode($name));
$s
->appendChild($dom->createElement('sIC'))
->appendChild($dom->createTextNode($ic));
$s
->appendChild($dom->createElement('sEmail'))
->appendChild($dom->createTextNode($email));
$s
->appendChild($dom->createElement('sAddress'))
->appendChild($dom->createTextNode($address));
$s
->appendChild($dom->createElement('sPhone'))
->appendChild($dom->createTextNode($nophone));

保存在同一个文件中：

$dom->save('phone_XML.xml');
echo "<script language='JavaScript'>alert('Add item succesful');</script>";
echo "<script language='JavaScript'>window.location = 'index.php';</script>";
?>

输出应该是这样的：

<phone>
<staff>
<s id="S001Akmal">
  <sName>Muhammad Nur Akmal Bin Mohd Halim </sName>
  <sIC>940228-10-6101</sIC>
  <sEmail>muhdnurakmal@velocity.net.my</sEmail>
  <sAddress>Lot 2863 Jalan Limau, Meru 42200 Klang</sAddress>
  <sPhone>012-3456789</sPhone>
</s>
<s id="S002Atikah">
  <sName> Nur Atikah Binti Rohizad </sName>
  <sIC>940421-14-6236</sIC>
  <sEmail>nuratikah@gmail.com</sEmail>
  <sAddress>No 24, Taman Saujana Impian, 43000 Kajang</sAddress>
  <sPhone>013-6752800 </sPhone>
</s>
</staff>
</phone>

Answer 2

您正在加载现有的 XML。这将包括一些带有空格的文本节点（换行符、缩进空格）。 DOM 在序列化过程中识别它们，并尝试在重新格式化时保留原始 XML（包括空白节点）。 DOMDocument::$preserveWhiteSpace 属性允许它在解析时删除空白节点。

其他要点：

• 您错过了s 元素节点。
• phone 元素节点是它在 DOMDocument 对象的属性中可用的文档元素。
• appendChild() 可以与 create*() 调用结合使用。它返回附加的节点。
• 添加文本节点。不要使用 createElement() 的第二个参数，它有一个损坏的转义。

放在一起：

$xml = <<<'XML'
<phone>
<staff>
    <s id="S001Akmal">
        <sName>Muhammad Nur Akmal Bin Mohd Halim </sName>
        <sIC>940228-10-6101</sIC>
        <sEmail>muhdnurakmal@velocity.net.my</sEmail>
        <sAddress>Lot 2863 Jalan Limau, Meru 42200 Klang</sAddress>
        <sPhone>012-3456789</sPhone>
    </s>
</staff>
</phone>
XML;

$document = new DOMDocument();
$document->formatOutput = TRUE;
$document->preserveWhiteSpace = FALSE;
$document->loadXml($xml);

$phone = $document->documentElement;
// appendChild() can be combined with the create*()
$staff = $phone->appendChild($document->createElement("staff"));

// you missed the `s` element node
$s = $staff->appendChild($document->createElement('s'));
$s->setAttribute('id', 'S002Doe');

$s
  ->appendChild($document->createElement('sName'))
  ->appendChild($document->createTextNode("John Doe"));
$s
  ->appendChild($document->createElement('sIC'))
  ->appendChild($document->createTextNode("123"));
$s
  ->appendChild($document->createElement('sEmail'))
  ->appendChild($document->createTextNode("john@example.tld"));
$s
  ->appendChild($document->createElement('sAddress'))
  ->appendChild($document->createTextNode("somewhere"));
$s
  ->appendChild($document->createElement('sPhone'))
  ->appendChild($document->createTextNode("456"));

echo $document->saveXml();

输出：

<?xml version="1.0"?>
<phone>
  <staff>
    <s id="S001Akmal">
      <sName>Muhammad Nur Akmal Bin Mohd Halim </sName>
      <sIC>940228-10-6101</sIC>
      <sEmail>muhdnurakmal@velocity.net.my</sEmail>
      <sAddress>Lot 2863 Jalan Limau, Meru 42200 Klang</sAddress>
      <sPhone>012-3456789</sPhone>
    </s>
  </staff>
  <staff>
    <s id="S002Doe">
      <sName>John Doe</sName>
      <sIC>123</sIC>
      <sEmail>john@example.tld</sEmail>
      <sAddress>somewhere</sAddress>
      <sPhone>456</sPhone>
    </s>
  </staff>
</phone>
