ABAP ALV展示时将内表转换成为XML格式

使用方法CL_SALV_EX_UTIL=>FACTORY_RESULT_DATA_TABLE以及CL_SALV_BS_TT_UTIL=>IF_SALV_BS_TT_UTIL~TRANSFORM可以将ALV展示的内表转换成XML格式，熟悉ABAP开发的各位朋友应该对传入的参数都不陌生，其中FIELDCATLG和DATA属于必输项，其他内容按需填入即可。这边推荐使用函数LVC_FIELDCATALOG_MERGE获取结构的FIELDCATLOG。

  LR_RESULT_DATA = CL_SALV_EX_UTIL=>FACTORY_RESULT_DATA_TABLE(
      T_SELECTED_ROWS             = LT_SEL_ROWS
      T_SELECTED_COLUMNS          = LT_SEL_COLS
      T_SELECTED_CELLS            = LT_SEL_CELLS
      R_DATA                      = LR_DATA
      S_LAYOUT                    = LS_LAYOUT
      T_FIELDCATALOG              = IT_FIELDCATELOG[]
      T_SORT                      = LT_SORT
      T_FILTER                    = LT_FILTER
      T_HYPERLINKS                = LT_HYPERLINKS
      S_CURRENT_CELL              = LS_CURRENT_CELL
      HYPERLINK_ENTRY_COLUMN      = HYPERLINK_ENTRY_COLUMN
      DROPDOWN_ENTRY_COLUMN       = DROPDOWN_ENTRY_COLUMN
      R_TOP_OF_LIST               = LR_TOP_OF_LIST
      R_END_OF_LIST               = LR_END_OF_LIST
      T_DROPDOWN_VALUES           = LT_DROPDOWN_VALUES ).

  CASE CL_SALV_BS_A_XML_BASE=>GET_VERSION( ).
    WHEN IF_SALV_BS_XML=>VERSION_25.
      L_VERSION = IF_SALV_BS_XML=>VERSION_25.
    WHEN IF_SALV_BS_XML=>VERSION_26.
      L_VERSION = IF_SALV_BS_XML=>VERSION_26.
  ENDCASE.

  XML_FLAVOUR = IF_SALV_BS_C_TT=>C_TT_XML_FLAVOUR_EXPORT.
  LS_XML_CHOICE-XML_TYPE = '04'.

  CALL METHOD CL_SALV_BS_TT_UTIL=>IF_SALV_BS_TT_UTIL~TRANSFORM
    EXPORTING
      XML_TYPE      = LS_XML_CHOICE-XML_TYPE
      XML_VERSION   = L_VERSION
      R_RESULT_DATA = LR_RESULT_DATA
      XML_FLAVOUR   = XML_FLAVOUR
      GUI_TYPE      = IF_SALV_BS_XML=>C_GUI_TYPE_GUI        
    IMPORTING
      XML           = XML.
