Class XMLConfigReader

java.lang.Object
  java.util.ResourceBundle
      org.icenigrid.gridsam.core.util.XMLConfigReader

public class XMLConfigReader
extends java.util.ResourceBundle

Reads structured resource text data from an XML file and store it on a hashtable.

The hashtable keys are taken from the value of the first attribute of the <item> elements.
The hash table values are hashtables containing the sub-items names as keys and the sub-items data as value.

Implementation notes

You instantiate the XMLConfigReader class in a program to read data from a XML file. Once the class is instantiated, it reads all the data in a XML file and loads into a DOM tree. Then it populates a hashtable so the getString method can be called to find text information based on a key and subkey.
