Hi,
I have troubles understanding this proxml library.
I’m trying to load the data but it has a simple error that i don’t know why it's happening.
  error: ArrayIndexOutOfBoundsexception: Array index out of range: 0

The second question is, what is the method to save new  “children” width attributes,

Thanks for the help
David


code:
//http://www.texone.org/proxml/
import proxml.*;

// create the root element be specific where the class is
proxml.XMLElement file = new proxml.XMLElement("position");

// create the color element
proxml.XMLElement col = new proxml.XMLElement("color");
proxml.XMLElement poi = new proxml.XMLElement("point");
XMLInOut xmlIO;

float x,y,r,g,b;
int counter;

void setup(){
 size(400,400);
 smooth();
 xmlIO = new XMLInOut(this);
 xmlIO.loadElement("position.xml");  
}

void draw(){
 background(r,g,b);
 ellipse(x,y,20,20);
}

void xmlEvent(proxml.XMLElement element){
 println(element.countAllChildren());
 proxml.XMLElement[] child = element.getChildren();

 for(int i = 0; i < child.length; i++){
   //println(child);
   proxml.XMLElement culor = child[i].getChild(0);
   
   r = culor.getFloatAttribute("r");
   g = culor.getFloatAttribute("g");
   b = culor.getFloatAttribute("b");
   
   proxml.XMLElement posi = child[i].getChild(1);
   x = posi.getFloatAttribute("x");
   y = posi.getFloatAttribute("y");
 
 }
 
}

void mouseReleased(){
 
 x = mouseX;
 y = mouseY;
 // col.addChild(new proxml.XMLElement("point"));
 poi.addAttribute("x",mouseX);
 poi.addAttribute("y",mouseY);
 // make the color element a child of the root element
 file.addChild(poi,1);
 file.addChild(col,0);

 // create an XMLInOut object to format the elements
 XMLInOut xmlInOut =  new XMLInOut(this);
 // and call saveElement.
 xmlInOut.saveElement(file, "position.xml");

}

xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<position>
 <color b="255" g="100" r="55"/>
 <point x="205" y="228"/>
</position>
