According to OCPP specs, your current output is closer to what's correct but still has many problems.

• The full OCPP URN you're using ends with .../2015/10/ which is for OCPP 1.6 but in your code, you're using WSDL for OCPP 1.5 which requires .../2012/06/ for URN.
• Per OCPP spec, camel-case idTag is correct field name for Authorize message.
• You need the root tag in the SOAP body.
• You need WSA (addressing) namespace xmlns:wsa="http://www.w3.org/2005/08/addressing" for addressing fields (MessageId, From, To, ReplyTo, RelatesTo and Action in the SOAP header.
• chargeBoxIdentity belongs to OCPP URN namespace.
• MessageId should be MessageID and it should not have mustUnderstand attribute.
• Action, To, ReplyTo and chargeBoxIdentity should have mustUnderstand="true" attribute. Others should not.
• As of OCPP 1.6 ReplyTo is required and should always have the value http://www.w3.org/2005/08/addressing/anonymous
• RelatesTo is required for responses only. This is a request.

Final version of the expected output should be like below:

    
        XXX01
        /Authorize
        123
        http://from-endpoint
        http://www.w3.org/2005/08/addressing/anonymous
        http://to-endpoint
    
    
        
            1234567
        
    

Note: I've set a bit meaningful namespace prefixes, you can set anything you like.
