I find that when I use the html library I have to make a few simple
changes to html-spec.rkt. It seems that <ins> and <del> are not treated
like <b> and <i> . You can see in this example that while <b> remains in
the enclosing <p>, <ins> does not. I also find that I have to allow
pcdata as a child of <ol> and <ul>. I don't know whether pcdata is
"supposed to" appear there but it often does in the wild.

#lang racket
(require (prefix-in h: html) (prefix-in x: xml))
(define (xml->list x)
(cond
[(x:pcdata? x) (x:pcdata-string x)]
[(x:entity? x) (list)]
[(x:element? x)
(list (x:element-name x)
(map xml->list (x:element-content x)))]
[(list? x) (map xml->list x)]))
(printf "~s\n" (xml->list (h:read-html-as-xml (open-input-string
"<p>Hello world <b>Testing</b>!</p>"))))
(printf "~s\n" (xml->list (h:read-html-as-xml (open-input-string
"<p>Hello world <ins>Testing</ins>!</p>"))))
