I have created a .pes file using PhysicsEditor and imported as xml and have added to my project. When I parsed it and created bodies, it is showing strange behavior. The mapping of bodies that I created in PhysicsEditor is totally different what I see in my application means the shapes I draw in PhysicsEditor are rendering differently in my app. Here is my xml and code to parse and add bodies to scene.
PhysicsEditor XML file:

And here is my code:
private void loadLevel() {
// TODO Auto-generated method stub

try {

if(stream != null) {

NodeList bodiesNodeList = root.getElementsByTagName("bodies");
for(int i = 0; i < bodiesNodeList.getLength(); i++) {
BodyDef bodyDef = new BodyDef();
bodyDef.type = BodyType.StaticBody;
bodyDef.fixedRotation = true;
Element bodiesElement = (Element)bodiesNodeList.item(i);
NodeList bodyList = bodiesElement.getElementsByTagName("body");

}
NodeList polygonList = fixtureElement.getElementsByTagName("polygon");
if(polygonList != null && polygonList.getLength() > 0) {
for(int m = 0; m < polygonList.getLength(); m++) {
PolygonShape polyShape = new PolygonShape();

}
}
polyShape.set(vectors);
fixtureDef.shape = polyShape;
}
body.createFixture(fixtureDef);
}
}
}
mScene.attachChild(bgSprite);
mPhysicsWorld.registerPhysicsConnector(new PhysicsConnector(bgSprite, body, false, false));
}
}
}
catch(Exception e) {
e.printStackTrace();
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Any idea where I am going wrong?
