Parser error in ABAP mapping

Question

Hi ,
  i am using the following ABAP mapping program
method if_mapping~execute .
data: t_edidc type table of edi_dc40,
ls_edidc type edi_dc40,
ls_edidc_h type edi_dc40,
t_edidd type table of edi_dd40,
ls_edidd_h type edi_dd40,
ls_idx_xmb type idx_xmb,
t_result type string,
t_resultc type string,
t_resultd type string.
data: ls_idx1 type idxporsm59.
data: t_segtyp type table of edilsegtyp,
el_segtyp type edilsegtyp,
el_released type segdefrel,
el_error_text type string.

<b> i am getting the following parse error in FM IDX_XML_TO_IDOC :
" unexpected symbol; expected '<', '</', entity reference, character data, CDATA section, processing instruction or comment "
can anybody help
points will be given

HI,
is it possible that you have to use "-" instead of "=" in this [ixmlfactory = cl_ixml=>create( ).] line ?
