Simple transformation

HI,
I have data in a xml string now i need to get this data in some structure in my abap program so do i need to create the transformation for that in transaction STRANS?
Is there a way to generate autonmatic transformation.
Please advise.
Many Thanks.
Albert

If your xml string comprises of a only a single strcuture, you can try the ST itself. For example I have a work area named W_DATA and the same is read into the lv_xml_data_string variable. This is the transformation I use
* Calling the transformation to send xml data to internal tables/work area
CALL TRANSFORMATION id
SOURCE XML lv_xml_data_string
RESULT w_data = <fs_warea>.
This example will explain you more,

Simple Transformation to deserialize an XML file into ABAP data structures?

I'm attempting to write my first simple transformation to deserialize
an XML file into ABAP data structures and I have a few questions.
My simple transformation contains code like the following
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates"
              xmlns:pp="http://www.sap.com/abapxml/types/defined" >
<tt:type name="REPORT" line-type="?">
<tt:node name="COMPANY_ID" type="C" length="10" />
<tt:node name="JOB_ID" type="C" length="20" />
<tt:node name="TYPE_CSV" type="C" length="1" />
<tt:node name="TYPE_XLS" type="C" length="1" />
<tt:node name="TYPE_PDF" type="C" length="1" />
<tt:node name="IS_NEW" type="C" length="1" />
</tt:type>
<tt:root name="ROOT2" type="pp:REPORT" />
    <QueryResponse>
    <tt:loop ref="ROOT2" name="line">
      <QueryResponseRow>
        <CompanyID>
          <tt:value ref="$line.COMPANY_ID" />
        </CompanyID>
        <JobID>
          <tt:value ref="$line.JOB_ID" />
        </JobID>
        <ExportTypes>
          <tt:loop>
            <ExportType>
               I don't know what to do here (see item 3, below)
            </ExportType>
          </tt:loop>
        </ExportTypes>
        <IsNew>
          <tt:value ref="$line.IS_NEW"
          map="val(' ') = xml('false'), val('X') = xml('true')" />
        </IsNew>
      </QueryResponseRow>
      </tt:loop>
    </QueryResponse>
    </tt:loop>
1. In a DTD, an element can be designated as occurring zero or one
time, zero or more times, or one or more times. How do I write the
simple transformation to accommodate these possibilities?
2. In trying to accommodate the "zero or more times" case, I am trying
to use the <tt:loop> instruction. It occurs several layers deep in the
XML hierarchy, but at the top level of the ABAP table. The internal
table has a structure defined in the ABAP program, not in the data
dictionary. In the simple transformation, I used <tt:type> and
<tt:node> to define the structure of the internal table and then
tried to use <tt:loop ref="ROOT2" name="line"> around the subtree that
can occur zero or more times. But every variation I try seems to get
different errors. Can anyone supply a working example of this?
3. Among the fields in the internal table, I've defined three
one-character fields named TYPE_CSV, TYPE_XLS, and TYPE_PDF. In the
XML file, I expect zero to three elements of the form
<ExportType exporttype='csv' />
<ExportType exporttype='xls' />
<ExportType exporttype='pdf' />
I want to set field TYPE_CSV = 'X' if I find an ExportType element
with its exporttype attribute set to 'csv'. I want to set field
TYPE_XLS = 'X' if I find an ExportType element with its exporttype
attribute set to 'xls'. I want to set field TYPE_PDF = 'X' if I find
an ExportType element with its exporttype attribute set to 'pdf'. How
can I do that?
4. For an element that has a value like
<ErrorCode>123</ErrorCode>
in the simple transformation, the sequence
<ErrorCode> <tt:value ref="ROOT1.CODE" /> </ErrorCode>
seems to work just fine.
I have other situations where the XML reads
<IsNew value='true' />
I wanted to write
<IsNew>
        <tt:value ref="$line.IS_NEW"
        map="val(' ') = xml('false'), val('X') = xml('true')" />
       </IsNew>
but I'm afraid that the <tt:value> fails to deal with the fact that in
the XML file the value is being passed as the value of an attribute
(named "value"), rather than the value of the element itself. How do
you handle this?

Try this code below:
data l_xml_table2 type table of xml_line with header line.
W_filename - This is a Path.
if w_filename(02) = '
    open dataset w_filename for output in binary mode.
    if sy-subrc = 0.
      l_xml_table2[] = l_xml_table[].
      loop at l_xml_table2.
        transfer l_xml_table2 to w_filename.
      endloop.
    endif.
    close dataset w_filename.
else.
    call method cl_gui_frontend_services=>gui_download
      exporting
        bin_filesize = l_xml_size
        filename     = w_filename
        filetype     = 'BIN'
      changing
        data_tab     = l_xml_table
      exceptions
        others       = 24.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
                 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    endif.

Using Simple Transformations with Objects tt:copy .. results in Exception

Question:
How can I serialize an ABAP-Object-Instanz with my own simple transformation?
In the sap-documentation I found the following solution for the serialisation of any data-objects.
"z_steffens_simple_transf":
<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
<tt:root name="ROOT"/>
<tt:template>
    <root>
      <tt:copy ref="ROOT"/>
    </root>
</tt:template>
</tt:transform>
Following the example I wrote this report:
report zspahr_test_simple_transf.
class serializable definition.
public section.
    interfaces if_serializable_object.
    data attr type string value 'Attribute'.
endclass.
method main_serializable.
    data: oref type ref to serializable,
          xmlstr type xstring.
    create object oref.
    call transformation id
      source root = oref
      result xml xmlstr.
    call function 'DISPLAY_XML_STRING'
      exporting
        xml_string = xmlstr.
    call transformation z_steffens_simple_object
      source root = oref
      result xml xmlstr.
    call function 'DISPLAY_XML_STRING'
      exporting
        xml_string = xmlstr.
endmethod.                    "main_
start-of-selection.
demo=>main_serializable( ).
Executing this report leads to an exception "CX_SY_REF_NOT_SUPPORTED".
The "standard" transformation "ID" ist working an translates my object-instance into an asXML representation:
<?xml version="1.0" encoding="utf-8" ?>
- <asx:abap xmlns:asx="http://www.sap.com/abapxml" version="1.0">
- <asx:values>
<ROOT href="#o3" />
</asx:values>
- <asx:heap xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:abap="http://www.sap.com/abapxml/types/built-in" xmlns:cls="http://www.sap.com/abapxml/classes/global" xmlns:dic="http://www.sap.com/abapxml/types/dictionary">

- <local.SERIALIZABLE>
<ATTR>Attribute</ATTR>
</local.SERIALIZABLE>
</prg:SERIALIZABLE>
</asx:heap>
</asx:abap>
How can I do this with my own Simple Transformation "ZSPAHR_TEST_SIMPLE_TRANSF" ?
I want to serialize my object using my own xml-structure, not the asXML-structure !

Steffen

Hi,
try like this,i think it may help you.
ABAP:
CALL TRANSFORMATION ztrans_test
      SOURCE
           root = partab
     RESULT XML lv_xstring.
Trnsformation:
<tt:root name="ROOT" type="?"/>
<tt:template>
<VALUES>
<VALUE_SOURCE>
        <tt:value ref=".ROOT"/>
</VALUE_SOURCE>
<VALUE_PARAM>
<tt:value ref="NAME"/>
<tt:value ref="VALUE"/>
</VALUE_PARAM>
</VALUES>
Thanks,

How to escape special characters in Simple Transformation

Hi Experts,
I have got a problem to get a well formed xml document from the below simple transformation. The content of maktx contains
special characters like & <, which are not allowed in a well formed XML-Document. But the result of the Simple Transformation
contains this charcters even after the transformation as you can the in the result below. Has anyone a hint how to escape the
characters included in the maktx.
The transformation for maktx, should be something like
Before: Material & < TEST
After: Material &amp &lt TEST
Report wihich calls the simple transformation
types:
BEGIN OF t_mat,
   matnr type matnr,
   maktx type maktx,
end of t_mat.
Data:
mat type t_mat,
xml_stream type xstring.
START-OF-SELECTION.
mat-matnr = '4711'.
mat-maktx = 'Material & < Test'.
CALL TRANSFORMATION ztest_st2
        SOURCE mat = mat
        RESULT XML xml_stream.

Hi Sandra,
First of all thaks for your quick answer to my problem.
I see what you mean and get the same result, if I am using data-type string instead of xstring. But the recommendation in the XML-Books of SAP is to use XSTRING to save memory and circumflex problems between Codepages, when writing the XML-Stream to a filesystem.
As you can see in the code abvoe I am using a SAP-FM to display the XML-Stream and this FM works only with XSTRING´s,
that is one reason why I don´t understand that it displays it in the wrong way.
Even the Debugger shows me for the XSTRING the wrong result. Does all that mean that the escaping will not be applyed if you are working with XSTING´s??

Simple transformation tt: utf-16 to utf-8 encoding

Hi,
(reposting here as no response in the ABAP General forum)
I have a simple transformation the results of which are written to a file using open dataset. The XML in the file is appearing with encoding utf-16 but I need utf-8. I tried placing the following line in the transformation but it did not work:
<xsl:output encoding="utf-8"/>
The only way it works is if I use type xstring for the result of the transformation and not string. I then have to convert the xml from xstring to string before writing to the file. This works but I was wondering if there was an easier way to change the encoding of a simple transformation (tt:) ?????????
Che

Hi All,
Reopening this old post, as I found that the same transformation and same program call results in an XML with utf-8 in a NW 7.30 system, while utf-16 in a NW 7.01 system!
Any ideas why would it happen like this? And if there's anything that can be done to make sure the encoding remains same in both the systems?

Simple transformation : deserialize

Hi,
I have a simple transformation that works if I serialize table data, but it doesn't work when I wan't to deserialize.
Here is my ABAP program that calls the transformation:
TYPES: BEGIN OF flight,
        f_id TYPE p LENGTH 5,
        data TYPE c LENGTH 40,
      END OF flight,
      tt_flight TYPE STANDARD TABLE OF flight
                      WITH DEFAULT KEY.
DATA: data1 TYPE flight.
DATA: data2 TYPE flight.
DATA: xml_string TYPE string.
DATA: tab_data TYPE tt_flight.
data1-f_id = '00001'.
data1-data = 'before'.
APPEND data1 to tab_data.
data2-f_id = '00002'.
data2-data = 'before'.
APPEND data2 to tab_data.
concatenate '<?xml version="1.0" encoding="iso-8859-2"?><XY><flights>'
                                   '<flight><id>11111</id><data>data1</data></flight>'
                                   '<flight><id>22222</id><data>data2</data></flight>'
                                   '</flights></XY>'
            into xml_string.
CALL TRANSFORMATION ...
SOURCE XML xml_string
RESULT root = tab_data.
And the transformation:
<?sap.transform simple?>

          </flight>
        </tt:loop>
      </flights>
    </XY>
</tt:template>
</tt:transform>
It won't update or append the content of the xml to my table.
I would like to read many "<flight><id>.....</id><data>......</data></flight>" lines and write them into the table "tab_data".
Could somebody please help me?
Thanks in advance,
Greg

Hi Greg,
try to address the root node with a period. Instead of
<tt:loop name="line" ref="ROOT">
use
<tt:loop name="line" ref=".ROOT">

Simple transformation with reference to ddic structures

Hi, experts,
we decide to use xml as the format when exchanging massive data with other applications. and we want to use simple transformation because according to the document it's more fast.
actually our file structure is determined by certain ddic structures, one xml file main contain several ddic structures , and they are all flat one, not deep structure.
the xml file may look like this:
<data>
<ddic1>[components of ddic structure 1 ]</ddic1>
<ddic2>[components of ddic structure 2 ]</ddic2>
</data>
i am new to ST,i am wondering that is it possible to make the ST more easy with the help of ddic structure? do i still need to declare the components one by one in the ST program?
BR.

It only runs ok with 2 internal tables because of the way you set up the XML string. It will run ok with 3 internal tables too. If you strip out the '<C>' nodes or move the '<C>' nodes around, you'll see what I mean (move the C nodes to the last B node). Each time you start a loop in a simple transformation, the internal table is initialized. So, you need to form your sample XML string differently, declare your internal tables differently (nested), or use XSLT for a little more power.

Simple Transformation - XML to Internal Table Error

I have a webservice call that returns XML. I need to transform a portion of the response to an internal table, but my simple transformation is not working with loop processing. I have read through most posts regarding the topic but they're either too old or related to serialization. There aren't any exceptions thrown, but I don't get any data in the internal table (PAPERWORK root). Below are some code snippets. Any ideas on the problem with the XSLT template? Thanks.
Sample XML:
<?xml version="1.0" encoding="utf-8" ?>
<PrintVersionDataSet>
<Result>
<ReturnCode>W</ReturnCode>
<ReturnMessage>There are reports with later version(s)</ReturnMessage>
</Result>

ABAP Call to Transform Data:
TRY.
CALL TRANSFORMATION Z_GA_PAPERWORK_VERS_WEBSVC
      SOURCE XML LS_RESPONSE-VERIFY_PRINT_VERSION_RESULT
      RESULT RESULT     = LS_RESULT
             PAPERWORK = LT_PAPERWORK.
    CATCH CX_ROOT INTO ROOT_EXCEPTION.
      CALL METHOD ROOT_EXCEPTION->IF_MESSAGE~GET_TEXT
        RECEIVING
          RESULT = LV_MESSAGE.
ENDTRY.

Upon further inspection and testing with a simple file and program, I can see that the XML structure isn't quite correct for the loop process. There needs to be a single <PAPERWORK> node, instead of one for each table line in the file. This should allow the loop to execute properly after a slight adjustment to the XSLT template.

Simple Transformation from ABAP to XML and back

Hi experts,
Can anyone provide me a simple example of a 'simple transformation' that will convert and internal table with more than one column into XML via a simple transformation.
I've spend days now reading SAP help and e-learning examples, but this just won't work and I am getting short dumps saying 'The goal was to access variable "ROOT". However, this access was notv possible.'
Here is my ABAP:

      xml_string type xstring.
do 3 times.
     move sy-index to: itab-counter, cnt_c.
     concatenate 'nameA' cnt_c into itab-aname.
     concatenate 'nameB' cnt_c into itab-aname2.
     append itab.
enddo.

Figured it out. The interla tables used in teh call transformation statement can never have a header line.

Your XML is strange, it looks like a mix of pdf form content (xfa) and identity transformation (asx).
Could you explain more ?
Anyway, I tried to find out the errors (not only cx_st_match_element, that was just a catch missing), it works with the following program. Here are the main issues I have found :
- always catch exception class cx_st_error when you use simple transformations (it contains cx_st_match_element and all other simple transformation exceptions)
- xml "asx:abap" and "asx:values" in your input XML are useless, they are only used by identity transformation ("ID"); you may keep them if you want, but I advise you to see why they are in the xml !
- Use same case in your tags (if xml contains in the transformation so that it corresponds to the input XML
- I renamed all abap names with prefix ABAP_ so that to clearly differentiate xml tags and abap field names (so that it is more easy to understand, for every sdn reader; I hope it will help as I didn't find many threads in the forum).

Simple Transformation XML to ABAP Content of tag with subtrees to string field

Hi,
I have an requirement in which I have to do a transformation from an XML file to an structure.
I need get the value of a tag that have subtrees and move that to a field in my structure.
Example:
<TAG1>value1</TAG1>
<TAG2>value2</TAG2>
<TAG3>
     <TAG4>value4</TAG4>
     <TAG5>value5</TAG5>
</TAG3>
Result expected in ABAP Structure:
field1 -> tag1
field2 -> tag2
field3 -> <TAG4>value4</TAG4><TAG5>value5</TAG5>
The contents of the tag TAG3 is variable, so I want to store it as a string.
Can I make this with Simple Transformation?
In my tests I can move only the value of each child tag for the given field structure.
This syntax dont work:
<TAG3 tt:value-ref="STRUCTURE.FIELD3"/>
Thanks and Regards,
Miguel Motta

Hi Miguel
Have a look at below snippets. Here I have tried to escape the text inside TAG3 so that it gets treated as single node during transformation.
ABAP code
DATA: BEGIN OF result,
        col1 TYPE string,
        col2 TYPE string,
        col3 TYPE string,
      END OF result.
DATA: xml_string TYPE string VALUE
'<ROOT> <TAG1>value1</TAG1> <TAG2>value2</TAG2> <TAG3> <TAG4>value4</TAG4> <TAG5>value5</TAG5> </TAG3> </ROOT>',
      part1 TYPE string,
      part2 TYPE string,
      part3 TYPE string.
*   Escape the text inside TAG3 tag
FIND REGEX '(.*<TAG3>)(.*)(</TAG3>.*)' IN xml_string SUBMATCHES part1 part2 part3.
IF sy-subrc EQ 0.
part2 = escape( val = part2 format = cl_abap_format=>e_xml_text ).
*      REPLACE ALL OCCURRENCES OF '<' IN part2 WITH '<'.
*      REPLACE ALL OCCURRENCES OF '>' IN part2 WITH '>'.
xml_string = part1 && part2 && part3.
ENDIF.
TRY.
* Display xml
    cl_abap_browser=>show_xml( EXPORTING xml_string = xml_string ).
* Deserialization
    CALL TRANSFORMATION zmtest
      SOURCE XML xml_string
      RESULT para = result.
* Check result
    WRITE:/ 'COL1=', result-col1,
          / 'COL2=', result-col2,
          / 'COL3=', result-col3.
CATCH cx_st_error.
* Error handling
    MESSAGE 'Error in Simple Transformation'
            TYPE 'I' DISPLAY LIKE 'E'.

Simple transformation XML to ABAP, runtime error: CX_ST_REF_ACCESS

Hi, all experts,
I got a runtime error CX_ST_REF_ACCESS, while I tried to use Simple Transformation to transfer XML-String to ABAP internal table.
Can anybody help me to fix the problem? Thanks very much. It's urgent.
The code of transformation like this:

        lf_short TYPE short_d,
      END OF ls_mdr_data,
     lt_result_data like TABLE OF ls_mdr_data.
If I call the transformation use the XML-String like:
<node type="MDRFOLDER" objid="50016122" name="MDR Root Folder" short="MDR Root"/>
I got the error CX_ST_REF_ACCESS:
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_ST_REF_ACCESS', was not caught and
    therefore caused a runtime error.
    The reason for the exception is:
    The goal was to access variable "LF_TYPE". However, this access was not
    possible.

ABAP Simple Transformation - How to save XML to file with CL_FX_WRITER?

Hello!
When calling a Simple Transformation program for transformation from ABAP to XML, it is possible to specify RESULT XML rxml as a class reference variable of type CL_FX_WRITER, which points to an XML writer.
How to handle CL_FX_WRITER in order to save XML to a file?
Thanks and regards,
Andrey

Hallo Rainer!
Many thanks. I have checked the profile parameter ztta/max_memreq_MB and it is set to 2048 MB in the development system. I hope, that won't be less on the client's machine. The only thing I did not clearly explained, is that I need to write XML data to the server. I am so sorry. Downloading to the local PC is very helpful for me also, but only for the test purposes.

Andrey

ABAP to XML File (Simple Transformation)

Hi guys,
this is my first question here and if I do something wrong please tell me about it.
I created my own simple transformation which I use in my program:
CALL TRANSFORMATION ZST_MAGAZYN_BB
     SOURCE lt_magazyn_rh = lt_magazyn_rh[]
            lt_mag_hdr = lt_mag_hdr[]
            lt_mag_hdr2 = lt_mag_hdr2[]
     RESULT XML xml_string.
Then I tried to use GUI_DOWNLOAD on "xml_string" but there is no content in output xml file (but file's size is not 0kb):
DATA: xml_table TYPE STANDARD TABLE OF string.
APPEND xml_string TO xml_table.
CALL FUNCTION 'GUI_DOWNLOAD'
   EXPORTING
     filename = 'C:\rh.xml'
   TABLES
     data_tab = xml_table.
I would really appreciate your help.

Try to change the path where you're saving the file.
I had the same problem once, it was authorization. I couldn't save in C:\ root.
Change filename = 'C:\rh.xml'   to    filename = 'C:\TEMP\rh.xml'.
Or try any other path, but C:\

Simple Transformation with very long XML element names

I am trying to write a program to deserialize XML documents using the Simple Transformation technique. There are many optional elements in the XML document, so I need to have conditional statements statements to avoid trying to process elements that are not in the document. The XML document, however, has several Element Names that are greater than 30 characters in length. The Simple Transformation technique seems to require ABAP data dictionary structures that mirror the schema of the XML document. But one cannot create structure component names that are greater than 30 characters in length. We don't have any control over the XML schema as the XML documents come from the US government. The ST fragment below shows the statement that I want to write, but since the ABAP Structure PlasticCardInformationGroup cannot have a component AuthorizationResponseInformation, the ST syntax checker yields an "Illegal Reference ADDITIONALPLASTICCARDINFORMATION" error message.
Does anyone know a way to avoid this error?
<tt:d-cond check="exist(TRS_TradingPartner_Agreement.TRS_FinancialTransaction.PlasticCardInformationGroup.AdditionalPlasticCardInformation)">
<ns2:AdditionalPlasticCardInformation>
<tt:attribute name="CardNetworkType" value-ref="TRS_TRADINGPARTNER_AGREEMENT.TRS_FINANCIALTRANSACTION.PLASTICCARDINFORMATIONGROUP.ADDITIONALPLASTICCARDINFORMATI.CARDNETWORKTYPE"/>
<tt:attribute name="DraftLocatorNumber" value-ref="TRS_TRADINGPARTNER_AGREEMENT.TRS_FINANCIALTRANSACTION.PLASTICCARDINFORMATIONGROUP.ADDITIONALPLASTICCARDINFORMATI.DRAFTLOCATORNUMBER"/>
</ns2:AdditionalPlasticCardInformation>

could anyone help me?
