Looks like the OP needs to RTFM. Here's an excerpt from an article by
David Mertz (http://www.ibm.com/developerworks/library/x-
matters29.html):
"""
pyRXP's tuple tree data structure

pyRXP (and RXP itself) uses an efficient, lightweight tree
representation of XML documents. Each node in a pyRXP tree is simply a
tuple of the form:

(tagname, attr_dict, child_list, reserved)


No specialized Python classes are used in the representation -- just
tuples, dicts, lists, and strings (and None in the reserved position).
Perhaps surprisingly, this form is adequate to represent all the
information in an XML document. The tagname is a straightforward
string; the attribute dictionary is a dictionary that maps attributes
to values, as you would expect. ***The child list is more subtle:
Strings can be interleaved with tuples in the list, indicating a mixed
content element.*** Moreover, an element that has no content is
represented by an empty child list, but a self-closed tag is
represented by None.
"""

"subtle" is not the word I would have used :-)
