The irresponsible clojure guild presents...
Parse html5 and play with the DOM with a clean API.
Supports clojure, clojurescript support is still experimental.

;; Parse HTML file
(def doc (parser/doc (slurp "my-file.html")))
;; Fetch all elements with class "small"
(dom/find-by-class doc :small)
;; Fetch all elements with attribute "value"
(dom/find-by-attr doc :value)
;; Fetch all elements with attribute "value" of 5
(dom/find-by-attr doc :value 5)
;; Get a single element with ID main-container
(def elem (dom/find-by-id doc :main-container))
;; Get all attributes
(dom/attrs elem)
;; Set attribute value
(dom/set-attr! elem :class "top-level")
;; Get the new attribute
(println (dom/attr elem :class)) => "top-level"
;; Get all children of the given element
;; (includes text and comments)
(dom/children elem)
;; Get all ONLY element children
(dom/child-elems elem)
;; Add a child element
(dom/append! elem (dom/make-element "div" {:class "row"}))
;; Detach children from parents

;; Add a sibling element to the current one
(dom/insert-after! elem (dom/make-element "div" {:id "footer"}))
;; Check that the sibling is correct
(println (dom/attr (dom/next-sibling elem) "id")) => "footer"
;; Transucer for finding javascript elements
(def xform (filter #(= "text/javascript" (dom/attr % "type"))))
;; Find all javascript script tags
(def javascripts (dom/find-by-tag "script" xform))
;; Perform advanced queries
(dom/query-all doc "p.small#introduction")
