UPS Shipping API - ShipmentConfirmRequest Error - php

Question

Hello I am creating a wordpress website for a client using WooCommerce. The site is complete but the client wants the ability to create shipments from the shop_order page. I have most of this figured out, the problem is my XML request to the UPS API. I have checked and recheck, and I cant seem to find the error:
<ShipmentConfirmResponse><Response><ResponseStatusCode>0</ResponseStatusCode><ResponseStatusDescription>Failure</ResponseStatusDescription><Error><ErrorSeverity>Hard</ErrorSeverity><ErrorCode>10002</ErrorCode><ErrorDescription>The XML document is well formed but the document is not valid</ErrorDescription></Error></Response></ShipmentConfirmResponse>
Below is my xml mark up with sensitive info hidden.
<?xml version="1.0" ?>
<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>******</AccessLicenseNumber>
<UserId>********</UserId>
<Password>********</Password>

I am almost there on this, but I am stuck at this road block. If anyone can shed some light into this it would be much appreciated.

Answer 1

It was the service code container it must be included in the package container. I had it before it. Took me quite a while to figure out this dumb mistake on my part.
Before:
...
<Service>
<Code>03</Code>
</Service>
<Package>
...
After:
...
<Package>
<Service>
<Code>03</Code>
</Service>
...
Thanks for the help, and yes UPS requires a strange XML format.

Answer 2

The XML processing instruction appears twice:
<?xml version="1.0" ?>
This indicates the presence of two distinct XML documnents:
<?xml version="1.0" ?>
<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>******</AccessLicenseNumber>
<UserId>********</UserId>
<Password>********</Password>
</AccessRequest>
and
<?xml version="1.0" ?>
<ShipConfirmRequest xml:lang='en-US'>
<Request>
<TransactionReference>
<CustomerContext>Customer Context</CustomerContext>
<XpciVersion>1.0</XpciVersion>
</TransactionReference>
<RequestAction>ShipConfirm</RequestAction>
<RequestOption>validate</RequestOption>
</Request>
<!-- ... -->
</ShipConfirmRequest>
