Using XMLElement I would like to find the number of times that "zombie" appears in the <state> tag (see example code below).

I can use .getChildCount() to find how many children there are overall, so it seems like there'd be some way to add a simple selector so that it only pulled the children I specify. I've played around with the other .get operators and I haven't gotten any results. Thoughts?

Here is my current processing code:

I want a pie chart with two values and I've started with a modified version of the pie chart example on processing.org

When I used the online processing.js editor, the color differentiation showed up, except when the values are 50/50 and they become the same color.

However, when I place this code in the standard processing editor on my computer, I get a circle of a solid color.

Is it possible to give each wedge a defined color? That would be easiest. But looking from how it's drawn I don't see how that can be done.

Here is the code I'm using:

size(200, 200);

background(255);

smooth();

noStroke();

int players = 16;

int humans = 8;

int diameter = 150;

int[] angs = {humans/players*100, 0, 0, 0, 100-humans/players*100};

float lastAng = 0;

for (int i = 0; i < angs.length; i++){

 fill(angs[i] * 3.0);

 arc(width/2, height/2, diameter, diameter, lastAng, lastAng+radians(angs[i]*3.6));

 lastAng += radians(angs[i]*3.6);  

}
