Simple XML Transformation: Dump on converting several elements into xstring

Former Member — Thu, 01 Feb 2007 11:46:11 GMT

Hi all,

I'm having troubles to use a simple transformation that creates a byte-string (xstring) as result. It is necessary for me to use a byte-string to have xml in UTF-8 format, because I need to transport data in file format between unicode and non-unicode systems.

I even tried to do things as simple as possible and took the SAP Example for simple transformations and just modified the result type...


* The code of the simple transformation
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates" template="temp1" version="0.1">
  <tt:root name="PARA1"/>
  <tt:root name="PARA2"/>
  <tt:template name="temp1">
    <X1>
      <tt:value ref="PARA1"/>
    </X1>
    <X2>
      <tt:value ref="PARA2"/>
    </X2>
  </tt:template>
</tt:transform>


* Simple Transformation with xstring result
DATA xml_string TYPE xstring.
DATA field1(10) TYPE c VALUE 'Field1'.
DATA field2(10) TYPE c VALUE 'Field2'.

CALL TRANSFORMATION zst_demo
  SOURCE para1 = field1
         para2 = field2
  RESULT XML xml_string.

DATA result1 LIKE field1.
DATA result2 LIKE field2.

CALL TRANSFORMATION zst_demo
  SOURCE XML xml_string
  RESULT para1 = result1
         para2 = result2.

When executing the code and using a string as result everything works fine, but when using a xstring I get a dump considering "ST_INVALID_XML" with action "OpenElement". Converting only one data element works fine with an xstring, but when trying to convert 2 parameters I get that dump.

Any hints or another post with information on how to solve this?

Kind regards, Karsten

Try this,


data: g_ixml type ref to if_ixml,
        g_stream_factory type ref to if_ixml_stream_factory,
        g_encoding type ref to if_ixml_encoding,
        ostream type ref to if_ixml_ostream.

DATA xml_string TYPE xstring.
DATA field1(10) TYPE c VALUE 'Field1'.
DATA field2(10) TYPE c VALUE 'Field2'.
constants: encoding type string value `utf-8`.

g_ixml = cl_ixml=>create( ).
g_stream_factory = g_ixml->create_stream_factory( ).
g_encoding = g_ixml->create_encoding( character_set = encoding
                                                           byte_order = 0 ).

ostream = g_stream_factory->create_ostream_xstring( string = xml_string ).
ostream->set_encoding( encoding = g_encoding ).

CALL TRANSFORMATION zst_demo
  SOURCE para1 = field1
                para2 = field2
  RESULT XML ostream.

This should work and you will have the xstring result in xml_string.

Hello Sumansen,

do you know how to change in transformation 'ID' encoding from 'utf-16' to 'utf-8' and how can I see this transformation code in general?

Thanks a lot.
