HTML Parsing Step?

At the end of our e-mail discussion in May I suggested we have a separate
step for parsing HTML.  I still think this is a good idea.  Anyone else?

"The excellence of grammar as a guide is proportional to the paucity of the
inflexions, i.e. to the degree of analysis effected by the language
considered."
