错误输出xml与谷歌地图API 3

Question

我想输出一个XML数据从我的数据库与谷歌API的数据。 我使用的代码there：

<?php 
require("phpsqlajax_dbinfo.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', $username, $password); 
if (!$connection) { die('Not connected : ' . mysql_error());} 

// Set the active MySQL database 

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

// Select all the rows in the markers table 

$query = "SELECT * FROM markers 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->saveXML(); 
?> 

与其他人一样，我得到这个错误：

error on line 2 at column 1: Extra content at the end of the document 

其实，当我打开网页的源代码，我有这样的：

<?xml version="1.0"?> 
<markers> 
    <marker name="Pan Africa Market" address="1521 1st Ave, Seattle, WA" lat="47.608940" lng="-122.340141" type="restaurant"/> 
    <marker name="Buddha Thai &amp; Bar" address="2222 2nd Ave, Seattle, WA" lat="47.613590" lng="-122.344391" type="bar"/> 
    <marker name="The Melting Pot" address="14 Mercer St, Seattle, WA" lat="47.624561" lng="-122.356445" type="restaurant"/> 
    <marker name="Ipanema Grill" address="1225 1st Ave, Seattle, WA" lat="47.606365" lng="-122.337654" type="restaurant"/>  
    <marker name="Sake House" address="2230 1st Ave, Seattle, WA" lat="47.612823" lng="-122.345673" type="bar"/> 
    <marker name="Crab Pot" address="1301 Alaskan Way, Seattle, WA" lat="47.605961" lng="-122.340363" type="restaurant"/> 
    <marker name="Mama's Mexican Kitchen" address="2234 2nd Ave, Seattle, WA" lat="47.613976" lng="-122.345467" type="bar"/> 
    <marker name="Wingdome" address="1416 E Olive Way, Seattle, WA" lat="47.617214" lng="-122.326584" type="bar"/> 
    <marker name="Piroshky Piroshky" address="1908 Pike pl, Seattle, WA" lat="47.610126" lng="-122.342834" type="restaurant"/> 
</markers> 

我找了一个答案，但无法找到任何工作......

错误是因为使用mysql。你必须使用mysqli。
