Error while downloading data from internal table into XML file

Question

hi all,
i developed a program to download data from into internal table to xml file like this.
tables: mara.
parameters: p_matnr like mara-matnr.
data: begin of itab_mara occurs 0,
            matnr like mara-matnr,
            ernam like mara-ernam,
            aenam like mara-aenam,
            vpsta like mara-vpsta,
      end of itab_mara.
data: lv_field_seperator type c,     " value 'X',
      lv_xml_doc_name(30) type c,    " string value ‘my xml file’,
      lv_result type i.
      lv_field_seperator = 'x'.
      lv_xml_doc_name = 'my xml file'.
types: begin of truxs_xml_line,
          data(256) type x,
      end of truxs_xml_line.
types:truxs_xml_table type table of truxs_xml_line.
data:lv_tab_converted_data type truxs_xml_line,
     lt_tab_converted_data type truxs_xml_table.
data: lv_xml_file type rlgrap-filename value 'c:\simp.xml'.
select matnr ernam aenam vpsta from mara into table itab_mara up to 5
       rows where matnr = p_matnr.
CALL FUNCTION 'SAP_CONVERT_TO_XML_FORMAT'
EXPORTING
   I_FIELD_SEPERATOR          = lv_field_seperator
  I_LINE_HEADER              =
  I_FILENAME                 =
  I_APPL_KEEP                = ' '
   I_XML_DOC_NAME             = lv_xml_doc_name
IMPORTING
   PE_BIN_FILESIZE            = lv_result
  TABLES
    I_TAB_SAP_DATA             = itab_mara
CHANGING
   I_TAB_CONVERTED_DATA       = lt_tab_converted_data
EXCEPTIONS
  CONVERSION_FAILED          = 1
  OTHERS                     = 2
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
open dataset lv_xml_file for output in binary mode.
loop at lt_tab_converted_data into lv_tab_converted_data.
transfer lv_tab_converted_data to lv_xml_file.
endloop.
close dataset lv_xml_file.
this program is syntactically correct and getting executed, but when i open the target xml file it is showing the following error.
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
XML document must have a top level element. Error processing resource 'file:///C:/simp.xml'.
will anyone show me the possible solution to rectify this error
thanks and regards,
anil.

Hi,
Here is a small sample program to convert data in an internal table into XML format and display it.
DATA: itab  TYPE TABLE OF spfli,
      l_xml TYPE REF TO cl_xml_document.
* Read data into a ITAB
SELECT * FROM spfli INTO TABLE itab.
* Create the XML Object
CREATE OBJECT l_xml.
* Convert data in ITAB to XML
CALL METHOD l_xml->create_with_data( name = 'Test1'
                                     dataobject = t_goal[] ).
* Display XML Document
CALL METHOD l_xml->display.
Here are some other sample SAP programs to handle XML in ABAP:
BCCIIXMLT1, BCCIIXMLT2, and BCCIIXMLT3.
Hope this helps,
Sumant.
