Hi just started using processing to aid my Arduino development, and have just ran into a brick wall.

So far I have rect that travels along the path of a line, which is positioned manually.

My initial goal is to calculate the position of the line with data from an xml file and have the rect go along that line, however I do not know how to access deep enough to get to the relevant data in my file.

Here is a snippet of the file:
Code:

- <slice>
- <dimension>
  <x>44.97449</x> 
  <y>43.25116</y> 
  <z>10.0</z> 
  </dimension>
- <para>
  <layerheight>10.0</layerheight> 
  <layerpitch>1.0</layerpitch> 
  <speed>1.0</speed> 
  </para>
- <layers num="1">
- <layer id="1">
- <loops num="6">
- <loop id="1">
- <line>
- <point>
  <x>9.74318372</x> 
  <y>2.10971198</y> 
  <z>-2.6</z> 
  </point>
- <point>
  <x>9.743058</x> 
  <y>2.11195086</y> 
  <z>-2.6</z> 
  </point>
  </line> 

It is the X, Y data from point I am trying to get.

Can anyone point me in the right direction please?

^_^

EDIT: Oh I see... nevermind I posted too soon
Code:

 String s2x = xml.getChild(2).getChild(0).getChild(0).getChild(0).getChild(0).getChild(0).getChild(0).getContent();
  String s2y = xml.getChild(2).getChild(0).getChild(0).getChild(0).getChild(0).getChild(0).getChild(1).getContent();
 

works nicely for me, seems messy though
