Function module ISR_GET_DATA_FROM_XML throwing dump.

Question

Hi All,
Function module ISR_GET_DATA_FROM_XML  throwing dump.
The dump says,
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
caught in
procedure "ISR_GET_DATA_FROM_XML" "(FUNCTION)", nor was it propagated by a
RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component.
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
Can you please help me in resolving this error.
PERFORM set_tag_constants.
set size of XML document
ld_size = id_size.
create the input stream
lr_stream = ir_ixml_stream_factory->create_istrea
     table = it_xml
     size  = ld_size ). create XML document object
lr_dom = ir_ixml_factory->create_document( ).
create parser
lr_parser = ir_ixml_factory->create_parser(
     stream_factory = ir_ixml_stream_factory

Thanks

Hi,
SELECT MBLNR     
           MJAHR     
           FROM MSEG
           INTO TABLE I_MKPF
           WHERE MBLNR IN S_MBLNR AND
                       MJAHR IN S_MJAHR.
IF I_MKPF  IS NOT INITIAL.
SELECT * FROM MSEG INTO TABLE O_MSEG FOR ALL ENTRIES IN I_MKPF
      WHERE MBLNR   =    I_MKPF-MBLNR
        AND MJAHR   =    I_MKPF-MJAHR
        AND MATNR   IN   I_MATNR
        AND WERKS   IN   I_WERKS
        AND LGORT   IN   I_LGORT.
ENDIF.
