XQuery wisdom of the day

XQuery blends the line between functional and procedural programming.

Simple queries are almost purely functional, but the more complex the query is (i.e., the larger the number of the "for" iterators) the more it starts resembling C code. While semantically it is not the case, it seems using C programming as analogy is helpful when learning how to build XQuery queries.
