[cl-who-devel] Parsing html and creating a new output
by Andrei Stebakov 25 Nov '07

25 Nov '07

I am using drakma to get the html and cl-html-parse to parse it. Let's say I need to parse and modify the html and use hunchentoot to handle the request giving out the new html. In cl-who I see only the macro with-html-output-to-string which prints html given a body of s-exp. In my case I will only have a list of s-exp like '(:div "some text"). If I give a list to with-html-output-to-string it will return an empty string. I am wondering is there a function inside cl-who that I can use to convert s-exp html list like '(:body "some body") to an HTML text? Or how can I use the with-html-output-to-string macro for the purpose? Thank you, Andrew

[cl-who-devel] Case-sensitive XML
by Ken Harris 12 Nov '07

12 Nov '07

Hi! I'm having trouble outputting case-sensitive XML using cl-who. The *downcase-tokens-p* variable claims to be the answer, but it only controls whether the output is all-upper-case or all-lower-case: (setq *downcase-tokens-p* nil) (with-html-output-to-string (s) (:twoWords)) => "<TWOWORDS/>" (setq *downcase-tokens-p* t) (with-html-output-to-string (s) (:twoWords)) => "<twowords/>" I don't get how this is supposed to help with case-sensitive XML: keywords (like all symbols) are case-folded by the CL reader before cl-who sees them, no? :twoWords => :TWOWORDS. To support generation of XML with mixedCase tags or attributes, I would think that cl-who would need to allow strings where it allows only keywords now. Or maybe I'm just completely missing something, because the question that prompted the creation of *downcase-tokens-p* was a camelCase attribute. Can cl-who support mixedCase tags/attributes? Or if it's as simple as changing (keywordp x) to (or (keywordp x) (stringp x)), would such a patch be well-received? thanks! - Ken
