XML PARSE sometimes gives two or more XML-EVENT of ATTRIBUTE-CHARACTERS in a row.
Given this string, notice the final letter T is delivered by itself.
There are two XML-EVENTs.
ATTRIBUTE-NAME : <effectiveIn>
ATTRIBUTE-CHARACTERS : <CPPAC>
ATTRIBUTE-CHARACTERS : <T>
Compile option XMLPARSE(XMLSS)
z/OS using the SAX parser.
Diagnosing the problem
This is working as designed as and documented.
Resolving the problem
You'll need to adjust your COBOL program for this possibility. See below "Migration guide" for the documentation. Then read the part under "ATTRIBUTE-CHARACTERS event (changed)"
In particular, this line explains the behavior change:
"You might have to modify your code that handles the ATTRIBUTE-CHARACTERS event to handle more than one..."
The same information is under the part "CONTENT-CHARACTERS event (changed)."
Use the reserved word XML-INFORMATION to determine if a split has happened.
If you don't use the XML-INFORMATION word, then here is a sample program that shows how to join the cut-apart pieces.
