I have a question: 

In the Processing 2.0 revisions.txt it reads for 
PROCESSING 2.0a6 
+ Fix whitespace issue with XML http://code.google.com/p/processing/issues/detail?id=975


I know it has been discussed before, but somehow I am still confused and don't 
understand this: If I open the "LoadingXMLObjects" example on Processing 2.08
and add println(xml.getChildCount()); or println(xml.getChildren().length); 
(which is equivalent) I both times get the result "7",
 allthough it should be "3". 
It seems a whitespace is still counted as a child.

Is that a known bug that is not fixable?

    * Loading XML Data
    * by Daniel Shiffman.  
    *
    * This example demonstrates how to use loadXML()
    * to retrieve data from an XML document and make
    * objects from that data
    *
    * Here is what the XML looks like:
    *
   <?xml version="1.0"?>
   <bubbles>
     <bubble>
       <diameter>40</diameter>
       <color red="75" green="255" blue="0"/>
     </bubble>
     <bubble>
       <diameter>20</diameter>
       <color red="255" green="75" blue="25"/>
     </bubble>
     <bubble>
       <diameter>80</diameter>
       <color red="100" green="150" blue="200"/>
     </bubble>
   </bubbles>
