cl_xml_document and type RAW on Unicode systems?

Former Member — Mon, 18 Feb 2008 15:02:02 GMT

Cheers guys,

I'm using a cl_xml_document for exporting data from but000 to an XML file. Works fine, except for the PARTNER_GUID which seems to be interpreted as chars (it's raw bytes), eg. the GUID "0E1E1FFCF746D14CADEF2D3EBEAEB21B" becomes "Dh4f/PdG0Uyt7y0+vq6yGw==". This is a very serious prob for us because it also occurs with other fields/tables and makes the whole XML thing pretty much useless.

Is there any known workaround for this?

Thx in advance!

Addition: the root of problem is the form Value_to_string (LSDIXMLF01) where RAW data gets converted to a string - this form is called from the SDIXML_DATA_TO_DOM function. I'd clearly say this is a bug (why would anyone want to apply a hex to string conversion to a GUID?), but I can't find anything about it on the OSS...

i tried to simulate your case and the finding is that if the source field data type is RAW (type BU_PARTNER_GUID) it behaves the way as you had explained.

however if you change the source field type(temporarily store them in a string field) to type string, it retains the format.

check this sample program.


data: l_xml  type ref to cl_xml_document  ,
     if_xml type ref to if_ixml_document ,
     node type ref to if_ixml_node  .
data: myguid type standard table of BU_PARTNER_GUID ,
      wa_guid type BU_PARTNER_GUID .
data: smyguid type standard table of string ,
      swa_guid type string .

data: xml_out type string ,
      xxml_out type xstring .
     wa_guid = '0E1E1FFCF746D14CADEF2D3EBEAEB21B' .
    append wa_guid to myguid .

swa_guid = '0E1E1FFCF746D14CADEF2D3EBEAEB21B' .
    append swa_guid to smyguid .

create object l_xml.
l_xml->set_data(
*    NAME        = 'DATA'
*    ALIAS       = ALIAS
    dataobject  = smyguid
*    PARENT_NODE = PARENT_NODE
*    CONTROL     = CONTROL
       ).


clear xml_out .
l_xml->render_2_xstring(
  EXPORTING
    PRETTY_PRINT = 'X'
  IMPORTING
*    RETCODE      = RETCODE
    STREAM       = xxml_out
*    SIZE         = SIZE
       ).

l_xml->render_2_string(
  EXPORTING
    PRETTY_PRINT = 'X'
  IMPORTING
*    RETCODE      = RETCODE
    STREAM       = xml_out
*    SIZE         = SIZE
       ).

call method l_xml->parse_string
  exporting
    stream = xml_out.
call method l_xml->display.

Hi, thx for the code, I'll try it ASAP and it looks like a good workaround. Still, I actually consider this behaviour a bug, but using a workaround is usually more effective than opening a case in SDN...
