Your next program will perform the same type of data extraction as was done in Listing 2.2. However, this time you'll adapt your traversal to the number of nodes by first determining what the number is and then using a loop to step through the array. Furthermore, the names of the nodes will be extracted and used as the labels. The XML data file that you'll use as your source will be Listing 2.3.
