Hi,
I've been trying to loop through an xml response getting it with curl and simpleXML. I can't figure out how to get at the values in the simpleXML object. Can you give me an example how to access them ie: a foreach loop perhaps? Nothing I'm trying seems to work.

<?php

//URL of targeted site
$url = "http://thedomaintowebservice.com";

$command = years;

$fields = array(
            'command' => urlencode($command),
            'year' => urlencode($year),
            'make' => urlencode($make),
            'trim' => urlencode($trim),
            'style' => urlencode($style),
            'account' => urlencode('myusername'),
            'key' => urlencode('mykey')
        );


//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER , 1 );

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);


$xml = new SimpleXMLElement($result);

?>

Open in new window


This is the xml being returned:

<?xml version="1.0"?>
<CBB>
<Response>
<DataVersion>20130114</DataVersion>
<Years>
<Year VINYear="D">2013</Year>
<Year VINYear="C">2012</Year>
<Year VINYear="B">2011</Year>
<Year VINYear="A">2010</Year>
<Year VINYear="9">2009</Year>
<Year VINYear="8">2008</Year>
<Year VINYear="7">2007</Year>
<Year VINYear="6">2006</Year>
<Year VINYear="5">2005</Year>
<Year VINYear="4">2004</Year>
<Year VINYear="3">2003</Year>
<Year VINYear="2">2002</Year>
<Year VINYear="1">2001</Year>
<Year VINYear="Y">2000</Year>
</Years>
</Response>
</CBB>

Open in new window


I tried this and it returns just the first year: 2013.

$xml = new SimpleXMLElement($result);

foreach ($xml->Response->Years as $year) {
    echo '<p>'.$year->Year.'</p>';
}

 I can't get my head around what I'm looping.
