I know the FCL already has a capable JSON parser, but I am writing some Amazon web service interfacing projects and wanted a smaller easier to use JSON parser to assist. I've create a new design for a JSON parser that is pretty small, yet powerful.

If your interested, I've posted the code under GPLv3 and a write up of my thought process and the workflow of using an single small class to work with JSON:

Any and all feedback is welcome.

Very cool library.
It would be nice if separator character can be change For example, for me personally
aval := n.find('billTo.name'). value;
more intuitive instead of
aval := n.find('billTo/name'). value;

Also AFAIK, GPL v3 license will require application using this library must use GPL too.

Adding a global redefinable separator character is a good idea which I might add. With regards to using the forward slash, I am just reusing the XPath way of doing things and was considering adding a few more XPath like queries. For example:

N.Find('/inventory/999/sku'); // search from root if the first path
character is '/', find the 999th node, return the sku
N.Find('//item[name="widget"]/price'); // search for the first item in the
entire document ('//') with a name of widget, return its price
N.Find('//item[recalled]/name'); // search for the first item with a
recalled node and return the name

And so on ...
