lQuery doesn't return text of elements in complex HTML documents

[fehmud]

lQuery doesn't return text of elements in complex HTML documents by using CSS selectors returned by browsers. jQuery in the JavaScript console doesn't work either, whilst CLSS does. Am I doing anything wrong?

For example, below is the code that I'm running on the HTML of lQuery's homepage - saved as "lQuery.html" - to get the documentation of FUNCTION ( TEXT NODE &OPTIONAL (TEXT NIL T-S-P) ). All calls to lQuery return #(), whilst calls to CLSS succeed.

Thanks for your attention.

(ql:quickload :lquery)

(defvar *html* (lquery:$ (initialize "lQuery.html")))

;; Using CSS Selector returned by Firefox
(lquery:$ *html*
          "#FUNCTION\\ LQUERY-FUNCS\\:TEXT > div:nth-child(2) > pre:nth-child(1)"
          (text))
;; => #()

;; Using selector returned by Chrome
(lquery:$ *html*
          "#FUNCTION\\ LQUERY-FUNCS\\:TEXT > div > pre"
          (text))
;; => #()

(setq *html* (plump:parse (uiop:read-file-string "Lquery.html")))

(plump:serialize (clss:select "#FUNCTION\\ LQUERY-FUNCS\\:TEXT > div:nth-child(2) > pre:nth-child(1)"
                              *html*))
;; => <pre>Get the combined text contents of each element [...]
      NIL

(plump:serialize (clss:select "#FUNCTION\\ LQUERY-FUNCS\\:TEXT > div > pre"
                              *html*))
;; => <pre>Get the combined text contents of each element [...]
      NIL

I can't reproduce. Works fine for me.

(lquery:$ *html* "#FUNCTION\\ LQUERY-FUNCS\\:TEXT > div:nth-child(2) > pre:nth-child(1)" (text))
; => #("Get the combined text contents of each element, including their descendants. If text is set, all text nodes are removed and a new text node is appended to the end of the node. If text is NIL, all direct text nodes are removed from the node. If text is not a string, it is transformed into one by PRINC-TO-STRING.")

Your mistake is passing a string to initialize. In that case it's assumed to be a string of HTML, not a path. Use a pathname, and it'll do what you expect.
