Question

以下是我的样本xml数据

 <?xml version="1.0"?>
<catalog>
   <book>
      <book NAME="ci_id">
        <PVAL><![CDATA[55190]]></PVAL>
      </book>

   <book>
      <book NAME="ci_id">

      </book>

</catalog>

我的要求是我必须根据pval id条件删除父节点（即＆lt; book＆gt;到＆lt; / book＆gt;）（例如：这里我删除pval = 55192）并且我需要更新新节点。

在下面的代码中，我已经基于pval成功删除了父节点，但是我无法添加新节点（即，它是一个字符串值）。请指导我。

$xmlFileToLoad   =  'client_temp/endeca_xml_search_feed/product/testing.xml';
      $xmlFileToSave   =  'client_temp/endeca_xml_search_feed/product/testing-modified.xml';

      $cdata_text = '
      <book>
         <book NAME="ci_id">
            <PVAL><![CDATA[78965]]></PVAL>
         </book>

         <description>Just i am testing.</description>
      </book>';

      $dom = new DOMDocument();
      $dom->load($xmlFileToLoad);
      $xpath = new DOMXPath($dom);

    function findStopPointByName($xml, $query) {
      $upper = "ABCDEFGHIJKLMNOPQRSTUVWXYZAZSCZCÓL";
      $lower = "abcdefghijklmnopqrstuvwxyzazscznól";
      $arg_query    = "translate(text(), '$upper', '$lower')";
      $q = "//book[book/PVAL[contains($arg_query, '$query')]]" ."\n";
      return $xml->query($q);
    }

    foreach(findStopPointByName($xpath,'55192') as $node)
    {
      $node->parentNode->removeChild($node);
       $node->appendChild( 
     $doc->createTextNode( $cdata_text ) );  
    }

    $dom->save($xmlFileToSave);

请告诉我如何添加节点（即字符串数据。这里是$ cdata_text）。

   foreach(findStopPointByName($xpath,'55192') as $node)
    {
      // Save parent - after removing node we will use it
      $parent = $node->parentNode;
      $parent->removeChild($node);

      // Load XML from text. You cann't append text, only node
      $data = new DOMDocument();
      $data->loadXML($cdata_text);

      // Import all new XML to our one and append to saved parent
      $ndata =  $dom->importNode($data->documentElement, true);   
      $parent->appendChild($ndata); 
    }
