PI54586: WITH XMLPARSE(COMPAT), AN EMPTY ATTRIBUTE VALUE INCORRECTLY GENERATES A SECOND ATTRIBUTE-NAME EVENT

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using XMLPARSE(COMPAT), an empty attribute like ATTR5=""
  generates two ATTRIBUTE-NAME events with XML-TEXT equal to the
  attribute name, rather than an ATTRIBUTE-NAME event followed by
  an ATTRIBUTE-CHARACTERS event with an empty XML-TEXT. For
  example, the XML fragment
  
      <ELEM5 ATTR5=""/>
  
  generates the event sequence:
  
      XML-EVENT           XML-TEXT
      ----------------    --------
      START-OF-ELEMENT    ELEM5
      ATTRIBUTE-NAME      ATTR5
      ATTRIBUTE-NAME      ATTR5  <-- in error
      END-OF-ELEMENT      ELEM5
