SOAP framework accessing XML element attributes

GrahamRobbo — Fri, 11 Dec 2015 05:55:16 GMT

Hi,

I have looked around and spent considerable time in the ABAP debugger without cracking this. Hope someone here can help me.

I have generated an ABAP SOAP proxy for consuming a web service. All works well.

This web service uses a generic method to retrieve data for any entity. To achieve this the response has the data stored in the XML element attributes rather than in the element content.

So instead of seeing something like this....


<Object>
  <Name>Fred</Name>
  <Address>1 Plane Street</Address>
  <City>Sydney</City>
</Object>

...I need to handle something like this...


<Object name="Fred" address="1 Plane Street" city="Sydney">
</Object>

I can't figure out how to do this from the generated proxy class. Has anyone come across this before?

Thanks

Graham Robbo

So the web service can be called and returns the correct data - you just can't access the top-level nodes attributes?

If that is the case you could get them via the PAYLOAD protocol (IF_WS_PAYLOAD).

i.e.

payload_handler = cl_proxy_access=>get_payload_handler(

proxy_name = 'CO_...'

proxy_method = 'EXECUTE_SYNCHRONOUS' ).

Then use "GET_PAYLOAD_FROM_RESPONSE_DATA()".

* Show payload for test purposes

lo_pointer = lo_payload->get_xml_pointer( ).

cl_proxy_service=>show_xml_document( lo_pointer-> ).

Querying the Payload - ABAP Web Services - SAP Library??

What's wrong with this editor - the formatting of my response above is all over the place - sorry about that.

Thanks mate - that link to the docu really helped. Not sure why I couldn't find that but you have saved my weekend.

Cheers

That just shows you are doing it right.
