You can always use the DOM or perform another XPath query:
for node in tr[x].childNodes:
<do something with node>
for node in tr[x].xpath(some_other_query_inside_tr):
<do something with node>

There's no need to parse anything again: just use the methods on the
object that tr[x] produces, including the xpath method, of course.
Remember that the document object is just a special node object, so
most of the methods are available on both. If in doubt, run your
program using Python's -i option and then inspect the objects at the
interactive prompt.
