[racket] xml processing question

(require xml) does not provide any special processing functions. You
can use normal pattern matching and functions on both the XML data
structures and the xexpr representation. I used 'match' a lot.

If you look on PLaneT, you will find a few processing libraries, like
an XPath implementation.

string->xexpr IS that
