hi mark

parsing refers to the analysis of the structure of the page

at least, that's my understanding  ;o)

remember parsing in english class in school?

    sentence ::= [noun phrase] [verb phrase]
    noun phrase ::=  [modifying clause] [adjectives] noun
    etc.   (you can tell i'm making this up)

html is parsed in a similar fashion -- the page consists of a head and a
body, the head contains title, metas, and scripts, the body contains....
well, you get the picture

one topic you may want to include in your tutorial is validation

go to http://validator.w3.org and you will see there is an option to show
the "parse tree" for the page being validated

tell your students to try it on a few pages and look at the parse tree that
their pages generate
