From Leafs to Branches - XML

Now we're making progress. We have effectively populated our Tree with leaf nodes. It is good, but not complete. Next, we will need to turn our leaf nodes into branches and give our new branches additional leaf nodes. We do this by adding child nodes to our XML groups. The Tree will automatically recognize that the top level nodes have children and change their icons to folders. Here is the updated XMLList:

<group label="Grains"> <food label="White Bread"></food> <food label="Wheat Bread"></food> <food label="Pasta Bread"></food> <food label="Oatmeal Bread"></food></group><group label="Dairy"> <food label="Milk"></food> <food label="Cheese"></food> <food label="Yogurt"></food> </group><group label="Fruits"> <food label="Apple"></food> <food label="Banana"></food> <food label="Citrus"></food> </group><group label="Meats"> <food label="Apple"></food> <food label="Banana"></food> <food label="Citrus"></food> </group><group label="Nuts"> <food label="Pecans"></food> <food label="Cashews"></food> <food label="Brazil Nuts"></food> </group>

Here is the Tree with branches and leaf nodes:

Now we have a successful Tree with leaf nodes.
