SAP ABAP XML XSLT with ABAP

Create ABAP coding

At first we create the internal table TYPES and DATA definition, we want to fill with the XML data. I have declared the table "it_airplus" like the structure from XML file definition for a better overview, because it is a long XML Definition (see the XSD file in the sample ZIP container by airplus.com)

*the declaration
TYPES: BEGIN OF t_sum_vat_sum,
       a_rate(5),
       net_value(15),
       vat_value(15),
      END OF t_sum_vat_sum.

TYPES: BEGIN OF t_sum_total_sale,
     a_currency(3),
     net_total(15),
     vat_total(15),
     vat_sum TYPE REF TO t_sum_vat_sum,
    END OF t_sum_total_sale.

TYPES: BEGIN OF t_sum_total_bill,
     net_total(15),
     vat_total(15),
     vat_sum TYPE t_sum_vat_sum,
     add_ins_val(15),
     total_bill_amount(15),
    END OF t_sum_total_bill.TYPES: BEGIN OF t_ap_summary,
     a_num_inv_det(5),
     total_sale_values TYPE t_sum_total_sale,
     total_bill_values TYPE t_sum_total_bill,
    END OF t_ap_summary.TYPES: BEGIN OF t_ap,
     head    TYPE t_ap_head,
     details TYPE t_ap_details,
     summary TYPE t_ap_summary,
    END OF t_ap.DATA: it_airplus TYPE STANDARD TABLE OF t_ap
