Using XML-INTO with a handler does not change the RPG data definition requirements. You still define everything the same way as you would if you weren't using a handler. For example if the XML looks like this:

<Customers>
   <RecordCount> 6 </RecordCount>
   <Company>Phones R Us</Company>
   <Company>Suchadeal Bank</Company>
   <Company>Rinky Dinky Toy Co.</Company>
   <Company>Partner400</Company>
   <Company>BlackHole Navigation</Company>
   <Company>Banker's Trust</Company>
</Customers>

Then the basic XML-INTO would be:

 d extractedData   DS          
 d  company                      32a   Dim(99)          
          
  /Free          
   XML-INTO company          
       %XML(XML_Input1: 'case=any' );          

If using handler it would look like this: (handling in 4 "unit" chunks)

 d HandleCompany   pr            10i 0
 d  commArea                     10i 0
 d  company                      32a   Dim(4) Const
 d  numElements                  10i 0 Value

  
  XML-INTO %Handler( HandleCompany: commArea )
           %XML(XML_Data : 'path=Customers/Company case=any' );

The handler will not break the document up into arbitrary pieces - it has to break it up into a number of repeated elements.
