get the element in an array object simplexml_load_string

jrough

I am trying hard to get the element from a simplexml array.
I tried these 3 ways

echo $parsed_xml->xpath('//Code');
echo $Code=$parsed_xml->xpath('str[@="error"]');
echo $newCode =(string)$Code;
foreach ($parsed_xml->Errors as $errors) {
echo $errors->Error, '<br />';
}
Result is :
ArrayArrayArray

How come I am not getting the element text?

Do a [man]print_r/man on the SimpleXML element so you can see its structure. If you still don't understand how to get the elements you want, post the output here (make sure you preserve the whitespace formatting, e.g. by using [noparse]

..

[/noparse] bbcode tags!) and let us know what it is you're after.

Thanks,😃😃

print_r output:
SimpleXMLElement Object ( [OperationRequest] => SimpleXMLElement Object ( [RequestId] => 1412a014-7c47-4503-b2be-c2d52567e3bc [Arguments] => SimpleXMLElement Object ( [Argument] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Operation [Value] => ItemLookup ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Service [Value] => AWSECommerceService ) ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Signature [Value] => 4CDSqyK65JHbDFBsRpo10sQKHi8QIQZQmRj77p4B8bQ= ) ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Version [Value] => 2009-01-06 ) ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => ItemId [Value] => B000BUR1 ) ) [5] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => IdType-ASIN ) ) [6] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => AWSAccessKeyId [Value] => AKIAIETJLADYILLAACBA ) ) [7] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Timestamp [Value] => 2010-05-22T18:56:58Z ) ) ) ) [RequestProcessingTime] => 0.0068230000000000 ) [Items] => SimpleXMLElement Object ( [Request] => SimpleXMLElement Object ( [IsValid] => True [ItemLookupRequest] => SimpleXMLElement Object ( [Condition] => New [DeliveryMethod] => Ship [IdType] => ASIN [MerchantId] => Amazon [OfferPage] => 1 [ItemId] => B000BUR1 [ResponseGroup] => Small [ReviewPage] => 1 [ReviewSort] => -SubmissionDate [VariationPage] => All ) [Errors] => SimpleXMLElement Object ( [Error] => SimpleXMLElement Object (

The point of using

 tags was to preserve the formatting of the print_r() output, not the PHP code you've already shown us.

View the source code of the page in your browser - the print_r() output should be a lot nicer (e.g. it has line breaks in it, rather than cramming everything together on the same line as you've done above).

Okay, sorry I missed the point. I didn't know the output could be formatted.

Here it is.

SimpleXMLElement Object ( [OperationRequest] => SimpleXMLElement Object ( [RequestId] => 81dd6451-0148-4250-9488-62f0d2479a3c [Arguments] => SimpleXMLElement Object ( [Argument] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Operation [Value] => ItemLookup ) ) [1] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Service [Value] => AWSECommerceService ) ) [2] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Signature [Value] => fRQANn34el96vZJXBVWoEHmq5yPWWmAHb4rBDSmM5Q4= ) ) [3] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Version [Value] => 2009-01-06 ) ) [4] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => ItemId [Value] => B000BUR1 ) ) [5] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => IdType-ASIN ) ) [6] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => AWSAccessKeyId [Value] => AKIAIETJLADYILLAACBA ) ) [7] => SimpleXMLElement Object ( [@attributes] => Array ( [Name] => Timestamp [Value] => 2010-05-22T20:02:59Z ) ) ) ) [RequestProcessingTime] => 0.0066750000000000 ) [Items] => SimpleXMLElement Object ( [Request] => SimpleXMLElement Object ( [IsValid] => True [ItemLookupRequest] => SimpleXMLElement Object ( [Condition] => New [DeliveryMethod] => Ship [IdType] => ASIN [MerchantId] => Amazon [OfferPage] => 1 [ItemId] => B000BUR1 [ResponseGroup] => Small [ReviewPage] => 1 [ReviewSort] => -SubmissionDate [VariationPage] => All ) [Errors] => SimpleXMLElement Object ( [Error] => SimpleXMLElement Object ( [Code] => AWS.InvalidParameterValue [Message] => B000BUR1 is not a valid value for ItemId. Please change this value and retry your request. ) ) ) ) )

I thought you were supposed to put the php in

tags. I never heard of the

tags.

By the way,
the structure of the error xml is as far as I can tell
The structure of the response message is:
<OperationREquest>
<Items>
<Item>
<ItemAttributes>
</ItemAttributes>
</Item>
</Items>
<Errors>
<Error>
<Message>
</Message>
<Code>
</Code>
<Error>
</ERrors>
<OperationRequest>
Without an error it eliminates the Errors section.

thanks,
