Help needed for Transforming XML into nested ITAB

Posted on Oct 17, 2006 at 09:21 AM 32 Views

Hi guys,

I am having problems converting this XML into a ITAB. Pls look thru and advise me on the XSLT codes cheers!

XML

<?xml version="1.0" encoding="iso-8859-1"?>

<PROCESS>TX-TIME-EXTENSION</PROCESS>

</gebizXML>

THE PROGRAM

TYPES: BEGIN OF GENERIC,

PROCESS TYPE STRING,

PAYLOAD TYPE STRING,

END OF GENERIC.

DATA: G_XML TYPE TABLE OF GENERIC.

DATA: xml_string TYPE string .

DATA: xslt_error TYPE REF TO cx_xslt_exception,

xslt_message TYPE string .

CLEAR xml_string .

CONCATENATE

`<?xml version="1.0" encoding="utf-8"?>`

`<G_XML timestamp="20051213T221545+08:00">`

`<PROCESS>TX SCHEDULE</PROCESS>`

`<PAYLOAD>this is a test of a string</PAYLOAD>`

`</G_XML>` INTO xml_string .

TRY .

CALL TRANSFORMATION (`ZSAMPLEX2A`)

SOURCE

XML xml_string

RESULT

G_XML = G_XML.

CATCH

cx_xslt_exception INTO xslt_error.

xslt_message = xslt_error->get_text( ).

ENDTRY.

 here is the code
 
 XSLT
 
 <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:sap="http://www.sap.com/abapxml" version="1.0"> <xsl:template match="/"> <asx:abap xmlns:asx="http://www.sap.com/abapxml"> <asx:values> <G_XML> <xsl:for-each select="gebizXML"> <G_XML1> <PROCESS> <xsl:value-of select="PROCESS"/> </PROCESS> <PAYLOAD> <xsl:value-of select="PAYLOAD"/> </PAYLOAD> </G_XML1> </xsl:for-each> </G_XML> </asx:values> </asx:abap> </xsl:template> </xsl:transform>
 
 program to test
 
 REPORT y_test_xml_tran. TYPES: BEGIN OF GENERIC, PROCESS TYPE STRING, PAYLOAD TYPE STRING, END OF GENERIC. DATA: G_XML TYPE TABLE OF GENERIC. DATA: xml_string TYPE string . DATA: xslt_error TYPE REF TO cx_xslt_exception, xslt_message TYPE string . CLEAR xml_string . CONCATENATE `<?xml version="1.0" encoding="iso-8859-1"?>` `<gebizXML>` `<PROCESS>TX-TIME-EXTENSION</PROCESS>` `<PAYLOAD>TEST</PAYLOAD>` `</gebizXML>` INTO xml_string . TRY . CALL TRANSFORMATION (`YSIMPLE_XML_TO_ABAP`) SOURCE XML xml_string RESULT g_xml = g_xml. CATCH cx_xslt_exception INTO xslt_error. xslt_message = xslt_error->get_text( ). ENDTRY.

hi,

chk this sample code.

here is the code sample using ixml library .

just create a report program and copy paste the following code.

if time permits, later on i will post the xslt program which you can use it call transformation.

REPORT y_test_xml.

DATA: l_ixml TYPE REF TO if_ixml,

l_ixml_sf TYPE REF TO if_ixml_stream_factory,

l_ostream = l_ixml_sf->create_ostream_xstring( xml ).

l_document->render( ostream = l_ostream ).

CREATE OBJECT l_xml.

CALL METHOD l_xml->parse_xstring

EXPORTING

stream = xml.

l_xml->render_2_string(

EXPORTING

pretty_print = 'X'

IMPORTING
- RETCODE = RETCODE
stream = xml_out

size = size

).

CALL METHOD l_xml->display.

Hope this is helpful.

do let us know how it goes.

Regards

**************************8

to read the xml data to abap itab you could parse node by node or write a XSLT to map it to your itab or use the following method. (add the following code to the earlier program)

data: result_xml type standard table of smum_xmltb .

data: return type standard table of bapiret2 .

after the statement

l_document->render( ostream = l_ostream ).

add
- converting xml to itab
call function 'SMUM_XML_PARSE'

exporting

xml_input = xml

tables

xml_table = result_xml

return = return .

now check the result_xml itab.
