could declare a huge variable and do an XM-INTO to extract it. My

pieces

but it didn't do it.

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.
