here is an example of how to read the message payload...
I will first get an XML document, and then ask for a path inside this xml.
ls_msgtab-msgguid is the message ID,
ls_msgtab-pid is the pipeline ID.
DATA: ls_msgtab TYPE sxmsmsgdsp,
lv_guid TYPE sxmsmguid.
DATA: li_ifmsg TYPE REF TO if_xms_message,
li_msg TYPE REF TO if_xms_message_xmb,
li_pay TYPE REF TO if_xms_payload,
lv_payxstr TYPE xstring.
DATA: ixmlfactory TYPE REF TO if_ixml,
iparser TYPE REF TO if_ixml_parser,
streamfactory TYPE REF TO if_ixml_stream_factory,
istream TYPE REF TO if_ixml_istream,
idocument TYPE REF TO if_ixml_document,
lv_xpath TYPE string,
root TYPE REF TO if_ixml_element,
el TYPE REF TO if_ixml_element,
vl TYPE string.
TYPE-POOLS: ixml.
CLASS cl_ixml DEFINITION LOAD.
ixmlfactory = cl_ixml=>create( ).
streamfactory = ixmlfactory->create_stream_factory( ).
CALL METHOD persist->read_msg_pub
EXPORTING
im_msgguid = ls_msgtab-msgguid
im_pid = ls_msgtab-pid
im_version = 000 " we take the first version
IMPORTING
ex_message = li_ifmsg.
li_msg ?= li_ifmsg.
li_pay = li_msg->get_payload_with_main_document( ).
if not li_pay is BOUND.
endif.
lv_payxstr = li_pay->getbinarycontent( ).
istream = streamfactory->create_istream_xstring( lv_payxstr ).
idocument = ixmlfactory->create_document( ).
iparser = ixmlfactory->create_parser(
stream_factory = streamfactory
istream = istream
document = idocument ).
iparser->parse( ).
lv_xpath = xpath.
root = idocument->get_root_element( ).
el = root->find_from_path( path = lv_xpath ).
