Question

我一直在尝试生成包含Google地图标记的XML文档，为此，我使用了Google的开发人员example。

我的代码：

<?php
// Start XML file, create parent node

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

// Opens a connection to a MySQL server

$connection=mysql_connect('localhost','root');
if (!$connection) {  die('Not connected : ' . mysql_error());} 

// Set the active MySQL database

$db_selected = mysql_select_db('maplocations', $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
} 

// Select all the rows in the markers table

$query = "SELECT * FROM location WHERE 1";
$result = mysql_query($query);
if (!$result) {  
  die('Invalid query: ' . mysql_error());
} 

header("Content-type: text/xml");

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

while ($row = @mysql_fetch_assoc($result)){  
  // ADD TO XML DOCUMENT NODE  
  $node = $dom->createElement("marker");  
  $newnode = $parnode->appendChild($node);   
  $newnode->setAttribute("name",$row['name']);
  $newnode->setAttribute("address", $row['address']);  
  $newnode->setAttribute("lat", $row['lat']);  
  $newnode->setAttribute("lng", $row['lng']);  
  $newnode->setAttribute("type", $row['type']);
} 

echo $dom->save('google.xml');

?>

执行此操作时遇到的错误如下：

error on line 1 at column 1: Document is empty

我已经设置了标题来输出调试文本，它不再生成任何错误。请帮忙吗？
