Is your walker method moving the children around the child list
for the parent? The DOM specifies that getChildNodes
returns a 'live' list of node children so that modifications to
the children list is immediately visible:
http://www.w3.org/TR/DOM-Level-2-Core/core.html#td-live
This would mostly explain the odd ordering of children
you see: 2 4 6 3 5
Two is the first tspan, When it is removed/moved the
second child is '4' (since '3' became the first), then
'6' is the third child ('3', '5', '6'). I'm not so sure
how you wind up with the '3' and '5'.
