Uploading xml file in a background job .

Question

Hi Experts ,
I am uploading a xml file from application server to internal table .
While uploading from presentation server I get the value of stream as ( first few lines )
Case 1 :
?<?xml version="1.0" encoding="utf-16" standalone=
"yes"?><WPUBON01>##  <IDOC BEGIN="1">##    <EDI_DC
40 SEGMENT="1">##      <TABNAM>EDI_DC40</TABNAM>##
but while uploading from  application server , I get :
Case 2 :
<?xml version="1.0" standalone="yes"?>##<WPUBON01>##  <IDOC BEGIN="1">##    <EDI
DC40 SEGMENT="1">##      <TABNAM>EDIDC40</TABNAM>##      <MANDT>108</MANDT>##
Difference is of  unicode 16 as seen in file from presentation server .
As a result File from Presentation server is getting uploaded in internal table , but not from Application Server . In this case internal table is coming blank .
I am using :
      CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
          EXPORTING
            text   = stream
          IMPORTING
            buffer = xstring
          EXCEPTIONS
            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.
here xstring is coming blank when you use same file from application server .
*Extract data from xsting to internal table
        CALL FUNCTION 'SMUM_XML_PARSE'
          EXPORTING
            xml_input = xstring
          TABLES
            xml_table = it_data
            return    = it_ret.
I am getting error it it_ret as :
line   1 col   1-unexpected symbol; expected '<', '</', entity reference, character data, CDATA section, processing instruction or comment
How to get file like case 1 . or how to convert to utf-16 ?
I am using :
OPEN DATASET l_filename FOR INPUT IN  BINARY MODE    .
DO.
READ DATASET l_filename INTO l_xml_line.
IF sy-subrc EQ 0.
APPEND l_xml_line TO l_xml_table.
ELSE.
EXIT.
ENDIF.
ENDDO.
CLOSE DATASET l_filename.
LOOP AT l_xml_table INTO l_xml_line.
c_conv = cl_abap_conv_in_ce=>create( input = l_xml_line-data
replacement
= space ).
c_conv->read( IMPORTING data = l_content len = l_len ).
CONCATENATE l_str1 l_content INTO l_str1.
ENDLOOP.
Help please ......

Hi Alpana ,
Thanks for the reply .
I already am uploading data in internal table . If you see through my question ,
My problem is modify  the error in xml file uploaded in  l_xml_table through read dataset .
My file has been uploaded   from application server as 
<?xml version="1.0" standalone="yes"?>
<WPUBON01>
  <IDOC BEGIN="1">
This file is getting changed while uploading from presentation server as 
?<?xml version="1.0" encoding="utf-16" standalone=
"yes"?><WPUBON01>##  <IDOC BEGIN="1">##    <EDI_DC
40 SEGMENT="1">##      <TABNAM>EDI_DC40</TABNAM>##
      <MANDT>108</MANDT>##      <DOCNUM>3C10000001
notice the addition   'encoding="utf-16" '  .
How to achieve this addition .
If i am uploading it frompresentation server it is getting uploaded in internal table successfully , but not from application server
so that i can parse this xml file into xstring successfulyy to get it into internal table thru function module
CALL FUNCTION 'SMUM_XML_PARSE'
          EXPORTING
            xml_input = xstring
            xml_input = l_string_output
          TABLES
            xml_table = it_data
            return    = it_ret.
Please help me in hanging the file stream .
Regards ,
