PHP : HTML formating is not happening while reading the content from XML

本文关键字：格式化 HTML XML 读取 PHP | 更新日期: 2023-09-27

我正在从XML文件中读取内容以显示网页内容，请参阅读取XML文件的代码片段，

    <html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title></title>
    </head>
    <body>
    <?php
    $arg = $_GET['content'];
    //echo $arg;
    $doc = new DOMDocument();
    $doc->load('History.XML');
    $contents = $doc->getElementsByTagName($arg);
    $content1 = $contents->item(0)->nodeValue;
    $content2 = $contents->item(1)->nodeValue;
    ?>
        <p> 
        <?php 
        echo <<<EOM
        $content1 
    EOM;
        ?> 
        </p> 
    </body>
</html>

XML文件内容有一些HTML格式化标签，如<b> <h3>等，但从XML读取和显示这些内容，HTML格式化没有发生。

nodeValue在您的情况下是所有文本节点的连接。
使用字符串DOMDocument::saveXML ([DOMNode $node [， int $options]])代替。

自包含的例子:

<?php
$arg = 'foo';
$doc = new DOMDocument();
$doc->loadxml('<x>
    <foo><h1>lalala</h1><b>xyz</b></foo>
    <foo>12345</foo>
</x>');
$contents = $doc->getElementsByTagName($arg);
$content1 = $contents->item(0);
$content2 = $contents->item(1);
?>
<html>
  <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title></title>
  </head>
  <body>
    <p><?php echo $doc->savexml($content1); ?></p> 
  </body>
</html>

打印

<html>
  <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title></title>
  </head>
  <body>
    <p><foo><h1>lalala</h1><b>xyz</b></foo></p> 
  </body>
</html>
