Pull values from SimpleXMLElement Object - php

Question

I'm using the namecheap API to do some stuff, it's the first time I've used a API and I'm running into a bit of a problem.
This is what I have so far:
$ApiKey = "**********************";
$ApiUser = "*****";
$UserName = "*********";
$ClientIP = "********";
$NamecheapURI = "https://api.namecheap.com/xml.response";
$executionURL = $NamecheapURI."?ApiUser=".$ApiUser."&ApiKey=".$ApiKey."&UserName=".$UserName."&Command=namecheap.domains.check&ClientIp=".$ClientIP."&DomainList=".$domain;
$xml = simplexml_load_file($executionURL);
print_r($xml);
When print $xml I am returned simple XML objects:
SimpleXMLElement Object
(
[#attributes] => Array
(
[Status] => OK
)
[Errors] => SimpleXMLElement Object
(
)
[Warnings] => SimpleXMLElement Object
(
)
[RequestedCommand] => namecheap.domains.check
[CommandResponse] => SimpleXMLElement Object
(
[#attributes] => Array
(
[Type] => namecheap.domains.check
)
[DomainCheckResult] => SimpleXMLElement Object
(
[#attributes] => Array
(
[Domain] => facebook.com
[Available] => false
[ErrorNo] => 0
[Description] =>
[IsPremiumName] => false
[PremiumRegistrationPrice] => 0
[PremiumRenewalPrice] => 0
[PremiumRestorePrice] => 0
[PremiumTransferPrice] => 0
[IcannFee] => 0
[EapFee] => 0
)
)
)
[Server] => PHX01APIEXT03
[GMTTimeDifference] => --5:00
[ExecutionTime] => 0.008
)
My question is beyond this, how do I move forward and pull data from this?
I've tried treating this as an array but I am getting nowhere, when using is_array() to test if it was an array it says it's not which I don't understand...
I apologise if this is a noob question, I am a bit new to this. In short, what do I need to do to pull data from this?
Thanks in advance!

Learning to use SimpleXML is much better than trying to convert it to arrays/json/anything else and simple (hence the name). A quick example...
$response = '<?xml version="1.0" encoding="UTF-8"?>
<CommandResponse Type="namecheap.domains.check">
<DomainCheckResult Domain="facebook.com">
<Element>1234</Element>
<Element>12345</Element>
</DomainCheckResult>
</CommandResponse>';
$xml = simplexml_load_string($response);
echo "DOmain=".$xml->DomainCheckResult['Domain'].PHP_EOL;
foreach ( $xml->DomainCheckResult->Element as $value) {
echo "Value=".(string)$value.PHP_EOL;
}
outputs...
DOmain=facebook.com
Value=1234
Value=12345
You have to adapt this to your own XML, but the idea is that if you want to access an element of an item you use object notation -> and if you need to get an attribute, use array notation [].
So in the above code, the first echo ($xml->DomainCheckResult['Domain']) gets the <DomainCheckResult> element and outputs the Domain attribute.
Then the foreach loop says fetch each <Element> within <DomainCheckResult> and output the value.
