parameter use in simple transformation

former_member413266 — Wed, 08 Jun 2016 21:35:47 GMT

Hi all,

I would like change the following simple transformation such that the underlined area is dynamic:

<?sap.transform simple?>

<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">

<tt:root name="JS_COMMAND_ID"/>

<tt:template>

<Jetstream xmlns=http://Jetstream.TersoSolutions.com/v1.0/CommandResponse>

I have created a parameter that I am able to successfully pass into the transformation:

<tt:parameter name="VERS" kind="in" type="STRING"/>

I can see that this parameter contains the correct value in the debugger. However, when I try to use it as so:

I receive an element mismatch error. I have also tried "$VERS" with no success either.

Any suggestions?

Did you try <Jetstream><tt:attribute name="xmlns" value-ref="VERS"/> ?

Sandra,

Thanks for your suggestion, however that approach results in an 'unknown root VERS' syntax error. I am now trying this:

While this passes syntax checking, I receive a "Error during access to the ref node "JSVERNUM'. The ref node is not defined or does not have the necessary type' error upon execution. (I realize I have a redundant variable in there, but when I try using the variable directly I get an 'unknown ROOT' message.) As mentioned previously, the value of the input parameter is correct, and I can see that the value of the variable is being assigned correctly. Now it insists that I use a ROOT defined variable in the tt:attribute statement, but flags an error if I try to set the value of this data ROOT.

Indeed, it seems the only solution is to define it as a root. Is that a problem?

This code works:

  DATA xml_string TYPE string.
  CALL TRANSFORMATION ztest
        SOURCE  var_xmlns = 'urn:test'
        RESULT  XML  xml_string.

The transformation :

<?sap.transform simple?>
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates">
 <tt:root name="VAR_XMLNS"/>
 <tt:template>
  <Jetstream>
   <tt:attribute name="xmlns" value-ref="VAR_XMLNS"/>
 value
 </Jetsream>
 </tt:template>
</tt:transform>

The result (in xml_string) :

<?xml version="1.0" encoding="utf-16"?>
<Jetstream xmlns="urn:test">##  value##  </Jetstream>
