XML-Into with %HANDLER

I'm looking all over for an answer to this but I'm a noob on this.

If I have an XML that has more than 1 level nested, do I define a %HANDLER
procedure for each element?

Jon's example processes this XML with one %Handler

<Customers>
<Company>Phones R Us</Company>
<Company>Suchadeal Bank</Company>
</Customers>

Do I need a separate handler for each nest in this example XML? What Data
structure would I pass?

<customers>
<customer>
<CustID>1001</CustID>
<CustName>John Smith</CustName>
<CustStatus>Active</CustStatus>
</customer>
<customer>
<CustID>1002</CustID>
<CustName>Jane Doe</CustName>
<CustStatus>Inactive</CustStatus>
</customer>
</customers>
