Does anybody here know how to use the valueForKey method (or some other method)

I have successfully defined a datasource (an XML stream). Here is an XML
snippet:
<waters>
<water>
<name water_id='79'>Agean Sea at Kos, Greece</name>
</water>
<water>
<name water_id='37''>Amazon River, Peru</name>
</water>
<water>
<name water_id='100'>Atlantic Ocean</name>
</water>
</waters>
I am able to successfully extract the values for each water's name, like this:
function coolHandler(event)
{
var d = dashcode.getDataSource("list");
var n = d.selection().valueForKey("name");
alert( n );
}
The result of this handler is an echoing of the value for the name element.
Unfortunately, I want to get the value for the water_id attribute, but I can't
for the life of me figure out how to access it.
I confess I am not the JavaScript expert, but I suspect the reason
you're having difficulty is because an element attribute is usually
considered a child of the element. Were I to hazard a guess, you'd need
to look at something like:
function coolHandler(event)
{
var d = dashcode.getDataSource("list");
var n = d.selection().valueForKey("name.water_id");
alert( n );
}
