How to query HTML documents

LAML supports a number of simple tree traversal functions that can extract information from HTML documents

(define doc
 (html 
  (head 
   (title "Table Examples"))
  (body 
    (p 'id "5" "First paragraph") 
    (p (em "Second") "paragraph")
    (div
      (p "Third paragraph")))))

All text in all paragraphs
- (find-asts doc "p" ast-text)
The first paragraph
- (find-first-ast doc "p")
All constituents that satisfy a given predicate
- (traverse-and-collect-all-from-ast doc (lambda (ast) ...) id-1)
