I was sending the string I mentioned starting with "var Categories = ....". Looks like I somehow need to translate the Categories and DB to some json tree, but I don't know how to do it. For output I need a lisp list/tree structure describing the same data something like '(:category "Cat1" (:name "Item1" :item-num 8) (:name "Item2" :iten-num 9)). Should I resort to flex/bison or I can just use the libraries available for common lisp? Thank you, Andrew On 6/10/08, Henrik Hjelte <henrik@evahjelte.com> wrote:
Hmm, what exactly are you parsing? Javascript? No in that case it can't be parsed. Not that json is not javascript, it is a subset of the javascript object notation.
What exaclty are you sending, in a string, to lisp?
Categories is an array, and DB is an object, so both have to be encoded to json. I would use some json client side library for that purpose. They are all around, in Dojo or Prototype or stand alone.

I have a web page which has a JavaScript defining some data in a form:
var Categories = [ {name:"Cat1 ", caption:escape("Category 1")}, {name:"Cat2 ", caption:escape("Category 2")}
];
var DB = new Object(); DB[Categories[0].name] = [ {name:escape("Item1"), item-num:8} ];
etc...
When I try to parse it with cl-json (using decode-json-from-string), I got errors because it can't accept things like variable definitions. Can I use cl-json to create a CL data from the JS data I mentioned or I should use some other tool?
Thank you, Andrew
