文档末尾的额外内容

Question

  

可能重复：
  XML Extra content at the end of the document

这是我的代码。

<?php
    $this->load->database();

// Start XML file, create parent node

$dom = new DOMDocument("1.0");
$node = $dom->createElement("markers");
$parnode = $dom->appendChild($node); 

    $query = $this->db->get('comboTable');
    $query = $query->result_array();
header("Content-type: text/xml"); 

// Iterate through the rows, adding XML nodes for each

foreach($query as $row)
{ 
  // ADD TO XML DOCUMENT NODE  
  $node = $dom->createElement("marker");  
  $newnode = $parnode->appendChild($node);   
  $newnode->setAttribute("name",$row['restaurantName']);
  $newnode->setAttribute("address", $row['address']);  
  $newnode->setAttribute("lat", $row['lat']);  
  $newnode->setAttribute("lng", $row['lng']); 
} 

echo $dom->saveXML();

＆GT;

它给了我一个错误，即文档末尾有额外的东西。但是当我测试输出时，它看起来是正确的。任何想法？
