XML to ABAP

[Former Member]

hello all,

my requirement is to read an XML file into a structure of type string, for that i have written an XSLT transformations but when am trying to pass the XML file to the parser am getting run time error saying

XSLT_BAD_SOURCE_CONTEXT

CX_XSLT_RUNTIME_ERROR

below is the code for calling XSLT program

TYPES: BEGIN OF ty_xml_line,

data(256) TYPE x,

END OF ty_xml_line.

DATA: gt_in type table of ty_xml_line,

gt_out type string.

DATA: xslt_error TYPE REF TO cx_xslt_exception,

xslt_message TYPE string .

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

filename = 'T:\Documents and Settings\sgolla\Desktop\xmlorder1.xml'

TABLES

data_tab = gt_in.

TRY .

CALL TRANSFORMATION zord1

SOURCE XML gt_in

RESULT xml_output = gt_out .

CATCH cx_xslt_exception INTO xslt_error.

xslt_message = xslt_error->get_text( ).

ENDTRY.

please help me how to solve it......

thx in advance

• The next step is creating the main factory for the iXML library:
