compare 2 XML and only get the differences back

Former Member — Tue, 15 Jul 2008 14:49:03 GMT

Hello ABAP XML experts,

I do not have an XI infrastructure, but need to perform a changes-only functionality in interfacing.

To achieve this I have a program which creates an XML string from an ABAP dictionary structure. I create this XML using the CALL TRANSFORMATION id statement. Then I store this XML in a custom database table.

The next time I run the interface program I create a new XML string and I read the one from the database, which I stored in the previous run of the program.

So far so good. Now the question.

Is there a standard function module, class or transformation who I can give the new and old XML and then it would compare the content and tell me which values have changed?

Kind Regards

Try COMPARE method of class CL_SXIVERI_XML_COMPARATOR.

Hi Patel,

the method sound promising, however I have my xml in a data field of type string and the method needs type XSTRING.

do you happen to know how to convert from string to XSTRING?

thanks
