Hello,
we are building an webservice that will be updating data. For simplicity, lets assume that there are 3 elements that can be updated (A as xs:string, B as xs:date and C as xs:integer).
We need to be able to distinguish whether element was ommited in the request (means - do not update), was present and was set to null value (empty string or xsi:nil, means - update and set to null), was present and was set to not null value (means - update to given value).
What is the best approach to accomplish this in Talend ESB? It seems like ommited elements and elements with empty/null value are both treated as "null" in tXMLMap.
Any advice appreciated.
Few examples:
<A>val1</A><B>2015-01-01Z</B><C>1</C> <!-- update all -->
<A>val1</A><C>1</C> <!-- update A and C, leave B unchanged -->
<A>val1</A><C xsi:nil="true" /> <!-- update A, leave B unchanged, set C to null -->
