PHP DOM 文件复制整个 table 到一个新的 div

Question

我从 jquery summernote 收到 HTML table 这样的

<div class="pasted">
   <table class="table table-bordered" style="width: 100%;">
      <tbody>
         <tr>
            <td>
              item 1
            </td>
         </tr>
       </tbody>
     </table>
</div>

现在我想使用 PHP

转换成这个

<div class="pasted">
   <div class="table-responsive">
      <table class="table table-bordered table-summernote1">
         <tbody>
            <tr>
               <td>
                 item 1
               </td>
            </tr>
         </tbody>
        </table>
   </div>
</div>

这是我的PHP代码：

<?php

$dom = new DOMDocument();
$dom->loadHTML($text, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

$b = $dom->getElementsByTagName('table');

foreach ( $b as $t )
{
    if ( $t->hasAttributes() )
    {
        foreach ( $t->attributes as $attr )
        {
            $t->removeAttribute($attr->nodeName);
        }

        $t->removeAttribute("style");

        $t->setAttribute('class', 'table table-bordered table-summernote1');

        $responsive  = $dom->createElement('div');
        $t->insertBefore($responsive);
        $responsive->setAttribute('class', 'table-responsive');

        $frag = $t->cloneNode(true);

        $responsive->appendChild($frag);
    }
}

?>

PHP 代码不起作用。页面在 $responsive->appendChild($frag) 上挂起并且处理永远不会结束。

我也试过 preg_replace 但没用

foreach ( $b as $t )
{
    if ( $t->hasAttributes() )
    {
        foreach ( $t->attributes as $attr )
        {
            $t->removeAttribute($attr->nodeName);
        }

        $t->removeAttribute("style");
    }
}

$text = $dom->saveHTML();

$text = preg_replace('/<table>(.*)<\/table>/isum', '<div class="table-responsive"><table class="table table-bordered table-summernote1"></table></div>', $text);

它只会转换前 1 或 2 tables。如果有多个 tables，一个 table 进入另一个 table.

解决这个问题的更好方法是什么？

似乎反对将克隆的节点添加到您克隆的节点中。我已经更改了 $responsive 添加的方式（添加到 table 的父级）并在添加克隆之前删除 $t 节点。

foreach ( $b as $t )
{
    if ( $t->hasAttributes() )
    {
        foreach ( $t->attributes as $attr )
        {
            $t->removeAttribute($attr->nodeName);
        }

        $t->removeAttribute("style");

        $t->setAttribute('class', 'table table-bordered table-summernote1');

        $responsive  = $dom->createElement('div');
        $t->parentNode->insertBefore($responsive, $t);
        $responsive->setAttribute('class', 'table-responsive');

        $frag = $t->cloneNode(true);
        $t->parentNode->removeChild($t);

        $responsive->appendChild($frag);
    }
}
