You've misunderstood me.

Now try using that same sort of procedural method to process a document,
rather than data, with a mixed content DTD such as

  <!ELEMENT p (#PCDATA|b|i)>
  <!-- rest of DTD snipped for brevity -->

For that sort of model you need an iterator, and to declare what you want
to do with <p>, <b> and <i> tag, rather than trying to find the children
directly.
