   RE: [xml-dev] Game of Life: an XSLT implementation

[ Lists Home | Date Index | Thread Index ]

Hi Roger,

If I understood well, the XML document for the starting configuration
contains 0s and 1s for each cell isn't it? If that is the case, I can do
even better; do an xml editor to create that document. 
The scenario would be:
a) An XSLT stylesheet transform (client side) an XML document containing a
default configuration. The document is derived from what you saw.
b) When users press the "edit" button, the table shows 0s and 1s that could
be edited.
c) When the users press the submit button, the simulation starts

I need to find ways to get the equivalent in Mozilla of the
"contentEditable" property available in IE. This property allows editing "in
place" the XHTML content. When the user press the submit button, a script
can use the DOM to update the XML document. Then we apply the templates on
the xml document.

We will have demonstrated a lot of features about 
a) Non linear systems.
b) Client side XML processing.
c) What you can do with XSLT as a development tool.
d) as soon as we have a version ported on Mozilla, a good demonstration of a
platform independent client side XML processing model; Could be useful as an
example of the possibilities. And who knows, maybe ignite some best practice
example in our community.

What do you think of that?

Hi Didier,

Great job!  That really looks nice.  Thanks.

I think that a useful parameter to the stylesheet would be one that
identifies the XML document that is to be the starting configuration.  I
can implement that quickly.  What other type of parameter were you
thinking of?  /Roger
