You should be able to use the ":contains(text)" pseudo-selector:

$("SectionAnswers SourceAnswerID:contains('64')", Section)

That will select the SourceAnswerID elements, so you might need to use the parent() or closest() function to move up the hierarchy.

I'm leaving this here for reference, since it could be useful in slightly different circumstances, but, like karim79 mentioned, it matches anything that has 64 as a substring.
