if you add this to the inner loop,
print titleNode.childNodes
print titleNode.firstChild.wholeText
you get this output (under 2.3.3):
[<DOM Text node "\n">, <DOM CDATASection node "Plone: rem...">]
Plone: remove member self registration

this bug report complains that the DOM represents the CDATA section as
four text nodes, which is also perfectly valid (see Martin's explanation). code
that depends on being able to identify a CDATA section in the source file is
broken; character data, character references, entities, and CDATA section
should all be treated as text.
btw, here's the corresponding ElementTree version:
from elementtree import ElementTree
tree = ElementTree.parse("foo.xml")
for node in tree.findall(".//blog"):
print node.get("id")
for content_node in node.findall("text"):
print content_node.findtext("blogtitle")
or, shorter:
for node in tree.findall(".//blog"):
print node.get("id")
print node.findtext("text/blogtitle")
