XML through HTTP send

Question

Hello,
I am having an requirement in which another web application would send XML through HTTP request to SAP which would be processed in SAP.
I was thinking to use BSP where the external web application would send HTTP request to BSP URL. I was trying to find some method of request object which will be able to get this message but not getting suitable method.
I tried using request->get_raw_message( ) but was not able to test. Basically i tried with sample msxml object using xmlhttp.send() method but couldn't find the response text.
has anyone tried such thing. In java we do have response.set

No i don't have that xhtmlb tag in my code.
my code is very very simple..
here is the code
Method onRequest
data: l_param type string value 't1'.
lv_input = request->get_cdata( ).
l_test = request->get_form_field( l_param ).
Method onInitialization
data: l_srno type i.
select max( SRNO ) into l_srno from ztesthttp.
if sy-subrc = 0.
  lv_num1 = l_srno + 1.
endif.
CALL FUNCTION 'Z_UPDATE_TEST'
EXPORTING
   HTTPMESSAGE       = l_test
   SRNO              = lv_num1
IMPORTING
   I_SUBRC           = i_subrc
   C_SUBRC           = c_subrc
i_subrc = sy-subrc.
and Layout
The return code for insert is <%=i_subrc%> and commit code is <%=c_subrc%><br>
        The requested string is: <%=lv_input%> and <%=l_test%> and <%=pg_test%>
Thanks..
