XQuery Question: FLWOR expressions?

1009726May 18 2013 — edited May 18 2013

Help. I am a bit confused and stuck on this question regarding XQuery.

Here's the XML for it.
URL: http://s3.amazonaws.com/spark-public/db/docs/courses-noID.xml

Return course numbers of courses that have the same title as some other course.

Please explain to me how to obtain the answer STEP-BY-STEP and the ANSWER. :) Good luck.
