Answer 1

XML parsing is pretty easy in actionscript 3 with E4X and somewhat similar to C#.

e.g.

var table:XML = 

 Calcium
 Ca
 
  118
 
 
  0.01
  0.1
 


trace(table.element.name);

Do checkout the E4X tutorial on the Yahoo Developer Network to get started easily. The rest should be easy enough.

For point 2 you should just loop through the element names and then enable their view/visual asset equivalent.

e.g.

for each (var element:XML in table.element.*) trace(element.name);//enable here instead of tracing

Update

I had a bit of fun with the great libspark SvgParser and the wikipedia periodic table svg. This is NOT how anyone should write code, this is just a quick and dirty test.

You can view the test here and the source here.

here's a preview:

Also displaying the C# version of parsing would help. And I found another great E4X article.
