Need help with adding some code to working page

[tsiedsma]

This code will take in three variables ($address, $city, $state) and find the longitude, latitude and zip code.

This uses the Yahoo! API geocoding service.

Here is the snippit of code I acquired from [a href=\"http://www.mapki.com/index.php?title=Batch_Geocode_Addresses\" target=\"_blank\"]MAPKI[/a]
[code]
$url = "http://api.local.yahoo.com/MapsService/V1/geocode?appid=xxxxxxxxxxx&street=".$address."&city=".$city."&state=".$state."";


$myFile = new XMLParser($url);

$xmlRoot = $myFile->data[0];  


if (sizeof($xmlRoot) > 0 ) {
        $geoLocation = $xmlRoot['child'];
        if (sizeof($geoLocation) > 0) {
                $geoLocationProperties = $geoLocation[0]['child'];
                for ($i = 0; $i < sizeof($geoLocationProperties); $i++) {
                        //echo $geoLocationProperties[$i]['name'] . " = " . $geoLocationProperties[$i]['content']."<br/>";
                    $map_data[strtolower($geoLocationProperties[$i]['name'])] = $geoLocationProperties[$i]['content'];
                }
        }
}
$long = $map_data['longitude'];
$lat = $map_data['latitude'];
$zip = $map_data['zip'];
[/code]
I acquired my own appid and embedded the code in my page. I have a form that passes variables to this page. 3 of which are $address, $city and $state. When I submit my form, I get the following error:

[b]Fatal error[/b]: Cannot instantiate non-existent class: xmlparser in [b]/home2/tsiedsma/public_html/crappyfiles/map2/update.php[/b] on line [b]20[/b]

Line 20:
[code]
$myFile = new XMLParser($url);
[/code]

Here is the code up to and including the yahoo api code I included.
[code]
<?
include 'dbax.php';

# grab the POST variables from the HTML form,
# put them into PHP variables so we can work with them
$name = $_POST['name'];
$address = $_POST['address'];
$city = $_POST['city'];
$state = $_POST['state'];
$phone = $_POST['phone'];
$email = $_POST['email'];
$ur = $_POST['ur'];
$status = $_POST['status'];
$ip = $_SERVER['REMOTE_ADDR'];
$approved = $_POST['approved'];

$url = "http://api.local.yahoo.com/MapsService/V1/geocode?appid=crappyfiles&street=".$address."&city=".$city."&state=".$state."";


$myFile = new XMLParser($url);

$xmlRoot = $myFile->data[0];  


if (sizeof($xmlRoot) > 0 ) {
        $geoLocation = $xmlRoot['child'];
        if (sizeof($geoLocation) > 0) {
                $geoLocationProperties = $geoLocation[0]['child'];
                for ($i = 0; $i < sizeof($geoLocationProperties); $i++) {
                        //echo $geoLocationProperties[$i]['name'] . " = " . $geoLocationProperties[$i]['content']."<br/>";
                    $map_data[strtolower($geoLocationProperties[$i]['name'])] = $geoLocationProperties[$i]['content'];
                }
        }
}
$lng = $map_data['longitude'];
$lat = $map_data['latitude'];
$zip = $map_data['zip'];
[/code]

I don't understand what the error means or what I need to do to fix it. Help me please.

You need to include the file that contains your xmlparser class definition.

I don't have one. I got that snippet of code from [a href=\"http://www.mapki.com/index.php?title=Batch_Geocode_Addresses\" target=\"_blank\"]http://www.mapki.com/index.php?title=Batch_Geocode_Addresses[/a].

I am just trying to make it work on my site.

What do I need to do?
