Hi,
I want to render scheme code inside script tag to be executed by biwascheme
in the browser so I've try to create simple page using sxml (cgi script):
(display "Content-Type: text/html")
(newline)
(newline)
(display "<!DOCTYPE html>")
(newline)
(sxml->xml `(html
(head
(title "BiwaScheme test")
(script (@ (src "biwascheme-min.js")) "(display \"hello\")"))
(body (p "BiwaScheme test"))))
but the output was:
<!DOCTYPE html>
<html><head><title>BiwaScheme test</title><script
src="biwascheme-min.js">(display
"hello")</script></head><body><p>BiwaScheme test</p></body></html>
which is invalid scheme code. I've also try this:
(script (@ (src "biwascheme-min.js")) "(display " #\" "hello" #\" ")")
but got the same result. How can I display raw data using sxml->xml
thanks in advance
Jakub

This one sticks out like a sore thumb :-) Note that embedded Javascript can be... interesting. How would you parse this: <script type="text/javascript> var kidding="the end of </script>"; # the above is just kidding </script> The html parser would have to parse the embedded script to grok that the first close tag is just fake. Strictly one has to quote (at least the '<') whithin the <script>, better to quote all the (five?) magic XML entities. So the generated code above seems OK. The client (aka browser) is supposed to unescape the text before handing it over to the script machinery. So if it doesn't, yo'd have to look there. That said, you could try the XHTML trick and wrap the script in a CDATA section. See e.g. [1], under "Differences Between HTML and XHTML" for an example.

I wised up a bit, to get an idea on how it's supposed to work (if there's such a thing on the Internet ;-) and found out: - in XHTML, the content of the script tag is parsed character data (#PCDATA). This means that entities (" and so on) *will be parsed and substituted*. Not so for HTML: there it's raw character data (#CDATA), and no entity substitution is supposed to happen [1] So your approach goes in the right direction. When outputting HTML, no substitution is supposed to be done (no " and no < and so on). - But how you keep your thing from tripping over some nasty </script> deeply embedded in the javascript text, then? The very readable [2] suggests: don't do it, then. That means: munge the javascript until it doesn't contain that nastygram. E.g. var nasty="</script\>"; Whee. Looks kinda cool, somehow. (that means you can only automate this task if you manage to kinda half-parse the provided javascript thing, right? But perhaps one can prove that "</" isn't a valid sequence in javascript outside a string literal?).

How can I display raw data using sxml->xml I googled “sxml CDATA” and found that Chicken Scheme has a “sxml-serialize” procedure that takes an optional keyword argument cdata-section-elements which is a list of elements which should have contents serialized to a CDATA section. It seems like if sxml->xml had something like that you might have a solution. Does <script><![CDATA[(display “hello”)]]></script> work on HTML?

As far as I understand, this is the way to do it in XHTML. In HTML it's at least... uncommon (I don't know whether it's officially sanctioned, but I guess the browsers will cope, somehow, as they always do :-) Ah, no. It's even funnier, see [1], [2] TL;DR: HTML doesn't know about CDATA. But if you want your thingie to parse as HTML *and* to validate as XML, you can do this: <script type="text/javascript"> //<![CDATA[ document.write("<"); //]]> </script> Otherwise the javascript processor would get passed "<![CDATA[..." and would freak out). I am speechless.
