I’ll probably do this if I were you:
#lang racket
(require xml)
(struct data (b1 b2) #:transparent)
;; extract :: XExpr -> (Listof data?)
(define (extract xexpr)
(match-define `(ROOT () ,xs ...) xexpr)
(for/list ([e xs] #:when (list? e))
(match-define `(A () ,b1 ,b2) e)
(data b1 b2)

Last I looked, `match` isn't great for XML, regardless of what
representation the XML is in.
You might want to make a DSL that does exactly what you want. Don't
expect the off-the-shelf tools to be great -- all the nea
I just cannot understand how to solve XML related problems by using this
library.
Perhaps there is lack of examples, and no description of functions purpose.
And from bare description I am failing to imagine practical use.
For example, why (source) struct exists? And how I can use it?
Why there

Thank you for your answer.
My guess from the beginning was that this related to HTML parsing and web
server packages.

One helpful thing to do is expand the GUI section of awesome-racket
https://github.com/avelino/awesome-racket
I just sent them a PR for GUI-helpers.
