I’m developing an application where I use wcf services . I use the web service the organization offer to:
  1. Send an xml schema populated with data
  2. Get a list of available web services
  3. Get a specific xsd schema
What I have to do is:
  1. Get a xsd schema form the authority and use this xsd to generate a xml populated with data
  2. Call the webservice where I can specify a number for a specific xsd schema , and get the xsd schema in return. Then I can validat my xml schema against it before I send it to the authority
  3. Use a web service where my xml string is in a string property of the wcf service and I send the xml file to the authority
My xsd looks (almost) like this:

VB.NET:
<?xml version="1.0" encoding="iso-8859-1"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:br="http://www.br.se/or" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <!--title='Tittle' lang='E'-->
    <xs:element name="Schema">

                <br:txt br:lang="E" br:txttype="LEDE">
                    <p>Some text</p>
                </br:txt>

        </xs:restriction>
    </xs:simpleType>
 
 
And som on for PayerNumber, PayerBirthDay, PAYerNAMe, PayerAdress, PayerPhone, PayerEmail…..
 
</xs:schema>

The elements in the xsd are structured as this:

Schema
Info​
Year​
TaskOwner​
TaskOwnerName​
TaskOwnerAdress​
TaskOwnerPhone​
TaskOwnerEmail​
TaskOwnerNumber​
Task​
TaskSpecialTask​
TaskOrdinaryTask​
Payers​
PaymentTotal​
NumberOfPayers​
PayersInfo (list of payers)​
PayerBirtNumber​
PayerBirthDay​
PayerName​
PayerAdress​
PayerPhone​
PayerEmail​


(Pleas ignore if something is left out in the xsd - it is there just so I can explain my problem better)

My question is, how should I generate the xml based on the xsd? Shoud I deserialize the xsd (with xsd.exe) so I get a class, create object of that class and populate it with data, and then serialize the object back to xml or should I keeping everything in the form of an in-memory XML document like this:

VB.NET:
Imports System.Xml
Imports <xmlns:xsi=http://..........>
 
Dim xmlDocument = 
                <Schema xsi:noSchemaNamespaceLocation=./relativePathTo/MySchema.xsd”>
                <Info>
                               ……. …..

The xsd schema change once a year, but mostly small changes.

What are the best approach for me, and why?

Thanks in advance!
