The "where" clause in a FLWOR structure is used to filter the results of the query based on specified criteria. This can replace the need for long and complicated predicates found in path expressions. The "for" clause is used to iterate over a sequence of items, the "let" clause is used to assign variables, and the "order by" clause is used to sort the results.
