Re: shopping cart : creating a new context

[Matthew Langham]

If you store the "goods" in the "cart" - why don't you just then add 
and remove items as needed using setxml and removexml. There is no need 
to copy the cart each time - it just stays in the session context.

That's right.
In fact, I try to solve one problem after the other, doing little 
steps, I
first tried to work out the basic fonctionnality. Now that I got it 
working,
I'm working on the issue you just mentionned. I think maybe an xsl
stylesheet mixed with the <session:mergexml> tag could do the trick. I 
have
no results yet (started working on it a few minutes ago).

The global algorithm for adding would be something like :

- copy actual cart (using "xsl:copy-of")
- select item list (xpath)
- merge new item to the list.
Your thoughts/help are very welcome!

hi julien

i like very much your very clean shoping-cart approach

and i consider to replace a javascripr based simple shoping cart with
something like yours but
as i see you set your cart (in session) at once, you are not able to 
add
or remove items thats right or is something i missed?

thnx in adv
