XML Syntax in Visual Cobol

I have a managed .NET class named Customer and  i need to write a method in order to create an XML file. How can i enable XML syntax in my Class? is there any sample code?

  •  There are a number of different methods that can be used to enable XML file creation in a COBOL program. The methods directly offered by Visual COBOL are documented here:

    There are also a set of .NET classes available for XML manipulation.

    The COBOL XML Syntax extensions should be used only within a COBOL procedural program that can then be called from within your method. This is because it uses a preprocessor which does not support the class syntax.

    A simple example of a program using the COBOL XML syntax is:

          $set preprocess(prexml) endp
           id division.
           program-id.   writexml.
           environment division.
           input-output section.
              select customers assign to "customers.xml"
                          organization is xml
                          document-type is omitted
                          file status is xml-status.
           data division.
           file section.
           xd customers.
           01 customerdb identified by "customerdb"
              count in customerdb-count.
              05 customer-record identified by "customer-record"
                 count in customer-record-count.
                 10 customer-id pic X(5) identified by "customer-id"
                    count in customer-id-count.
                 10 customer-name pic X(20) identified by "customer-name"
                    count in customer-name-count.
           working-storage section.
           01 xml-status   pic s9(9) value 0.
           procedure division.
               open output customers
               display xml-status
               move "12345" to customer-id
               move "john smith" to customer-name
               write customerdb
               display xml-status
               close customers
               stop run.

    If you wish to use the .NET classes directly within your method then an example would be:

          $set ilusing "System.Xml"
           class-id WindowsFormsApplication1.Form1 is partial
                     inherits type System.Windows.Forms.Form.
           working-storage section.
           method-id NEW.
           procedure division.
               invoke self::InitializeComponent
           end method.
           method-id button1_Click final private.
           procedure division using by value sender as object e as type System.EventArgs.
                declare writer as type XmlTextWriter = new XmlTextWriter("product.xml", type System.Text.Encoding::UTF8)
                invoke writer::WriteStartDocument(true)
                set writer::Formatting to type Formatting::Indented
                set writer::Indentation to 2
                invoke writer::WriteStartElement("Table")
                invoke createNode("1", "Product 1", "1000", writer)
                invoke createNode("2", "Product 2", "2000", writer)
                invoke createNode("3", "Product 3", "3000", writer)
                invoke createNode("4", "Product 4", "4000", writer)
                invoke writer::WriteEndElement
                invoke writer::WriteEndDocument
                invoke writer::Close
                invoke type MessageBox::Show("XML File created ! ")
           end method.
           method-id createNode public.
           procedure division using pID as string, pName as string, pPrice as string, writer as type XmlTextWriter.
                invoke writer::WriteStartElement("Product")
                invoke writer::WriteStartElement("Product_id")
                invoke writer::WriteString(pID)
                invoke writer::WriteEndElement
                invoke writer::WriteStartElement("Product_name")
                invoke writer::WriteString(pName)
                invoke writer::WriteEndElement
                invoke writer::WriteStartElement("Product_price")
                invoke writer::WriteString(pPrice)
                invoke writer::WriteEndElement
                invoke writer::WriteEndElement
           end method.
           end class.
