Formatting issue in XML file download

I am using CALL TRANSFORMATION to convert the internal table data into XML string. Then I am using TRANSFER statement to write the XML string to the application server file.

There is no issue in downloading the XML file into application server. The issue occurs when we open a HUGE XML file. We are getting formatting errors like

In a textpad, single line, the maximum number of characters is 65559 (not sure..this is what I get) and because of this sometimes a LINE BREAK occurs on a TAG. This causes the issue.

Is there any way to download the data from the XML string with correct formatting?

    CALL TRANSFORMATION doesn't work well with huge internal tables.

    You can create your own XML document with interface IF_IXML_DOCUMENT defined in package SIXML. You can find examples and much more.

    Find in blogs all about XML .There are several pages about the theme

    hi,

    here is the procedure which will solve ur problem:

    Firstly exported the data to memory using the FM LIST_FROM_MEMORY.

    *CALL FUNCTION 'LIST_FROM_MEMORY'*
    TABLES
    listobject = t_listobject
    EXCEPTIONS
    not_found = 1
    OTHERS = 2.
    IF sy-subrc 0.
    MESSAGE e000(su) WITH text-001.
    ENDIF.
    
    *then i converted it into ASCII using LIST_TO_ASCI,*
    
    *CALL FUNCTION 'LIST_TO_ASCI'*
    TABLES
    listasci = t_xlstab
    listobject = t_listobject
    EXCEPTIONS
    empty_list = 1
    list_index_invalid = 2
    OTHERS = 3.
    IF sy-subrc NE 0.
    MESSAGE e003(yuksdbfzs).
    ENDIF.
    
    *This gives the data in ASCII format separated by '|' and the header has '-', dashes. If you use this internal table directly without any proccesing in SO_NEW_DOCUMENT_ATT_SEND_API1, then you will not get a good excel sheet attachment. To overcome this limitation, i used cl_abap_char_utilities=>newline and cl_abap_char_utilities=>horizontal_tab to add horizontal and vertical tabs to the internal table, replacing all occurences of '|' with*
     
    *cl_abap_char_utilities=>horizontal_tab.*
    
    *Set the doc_type as 'XLS', create the body and header using the packing_list and pass the data to be downloaded to SO_NEW_DOCUMENT_ATT_SEND_API1 as contents_bin.*
    *This will create an excel attachment.*
    
    
    
    *Sample code for formatting the data for the attachment in excel format.*u2022	
    
    
    
    *Format the data for excel file download* 
    
    LOOP AT t_xlstab INTO wa_xlstab .
    DESCRIBE TABLE t_xlstab LINES lw_cnt.
    CLEAR lw_sytabix.
    lw_sytabix = sy-tabix.
    
    
    *u2022	If not new line then replace '|' by tabs* 
    
    
    IF NOT wa_xlstab EQ cl_abap_char_utilities=>newline.
    REPLACE ALL OCCURRENCES OF '|' IN wa_xlstab
    WITH cl_abap_char_utilities=>horizontal_tab.
    MODIFY t_xlstab FROM wa_xlstab .
    CLEAR wa_xlstab.
    wa_xlstab = cl_abap_char_utilities=>newline.
    IF lw_cnt NE 0 .
    lw_sytabix = lw_sytabix + 1.
    
    
    *u2022	Insert new line for the excel data* 
    
    
    INSERT wa_xlstab INTO t_xlstab INDEX lw_sytabix.
    lw_cnt = lw_cnt - 1.
    ENDIF.
    CLEAR wa_xlstab.
    ENDIF.
    ENDLOOP.
