It is the opposite of my load-markup function. My example was poor.

Yep. These are what load-markup and form-markup actually use to produce
their results.
All I am doing with load-markup is to first do LOAD/MARKUP an to change each
tag!
into a block! so that manipulating the attributes of the tag is much easier.
form-markup just converts the block back to a string so that you can for
example
write out that html file you just edited.

You could have tried that for yourself! :^)
>> m: load-markup {<body bgcolor="white">some <b>text</b></body>}
== [[body bgcolor "white"] "some " [b] "text" [/b] [/body]]
>> change next find first m 'bgcolor "blue"
== []
>> m
== [[body bgcolor "blue"] "some " [b] "text" [/b] [/body]]
>> form-markup m
== {<body bgcolor="blue">some <b>text</b></body>}

You're most welcome.
