XML Parsing Error

[whereschp]

This is the code.

<?php
header('Content-Type: text/xml;charset=UTF-8');

//see Listing 3-9 for icon related items in the code

$lat = (float)$_GET['lat'];
$lng = (float)$_GET['lng'];
$name = htmlspecialchars(strip_tags(utf8_encode($_GET['name'])));
$address = htmlspecialchars(strip_tags(utf8_encode($_GET['address'])));
$type = htmlspecialchars(strip_tags(utf8_encode($_GET['type'])));

//Create an XML node
$marker = <<<MARKER
<marker lat="$lat" lng="$lng" name="$name" address="$address" type="$type"/>
MARKER;

//open the data.xml file for appending
$f=@fopen('data.xml', 'a+');
if(!$f) die('<?xml version="1.0"?>
<response type="error"><![CDATA[Could not open data.xml file]]></response>
');

//add the node
$w=@fwrite($f, $marker);
if(!$w) die('<?xml version="1.0"?>
<response type="error"><![CDATA[Could not write to data.xml file]]></response>');

@fclose($f);

?>

 

And after more than one line is entered in the xml file is returns this.

It's not a valid xml document.  Xml documents usually start with a XML declaration (<?xml version="1.0" encoding="UTF-8" ?>) followed by a root element which contains all your other elements.  You need something like this:

<?xml version="1.0" encoding="UTF-8" ?>
<markers>
    <marker .... />
    <marker .... />
</markers>

 

If you're appending to an existing xml document, you'll probably need to parse it with one of the xml libraries and then insert your node.
