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
