== HierarchicalXMLConfiguration Example ==
The following is hopefully a helpful example of how to use the HierarchicalXMLConfiguration class as there appears to be a complete lack of doco on the jakarta site.

The example uses the following xml file and demonstrates how to read the configuration details from it.

{{{
<?xml version="1.0" encoding="ISO-8859-1" ?>

<Repositories>
	<Repository>
		<workspaceName>svn://nicole/doc</workspaceName>
	        <type>Subversion</type>
	        <username></username>
    		<password></password>
	</Repository>
	<Repository>
		<workspaceName>svn://nicole/doc/test</workspaceName>
	        <type>Subversion</type>
        	<username></username>
	    	<password></password>
	</Repository>
	<Repository>
		<workspaceName>svn://nicole/doc/test/3</workspaceName>
	        <type>Subversion</type>
	        <username></username>
	    	<password></password>
	</Repository>
</Repositories>

}}}


The following code reads the details of each repository entry in turn.

{{{
	static public void main(String[] args)
	{
		try
		{
			HierarchicalXMLConfiguration conf = new HierarchicalXMLConfiguration();
			conf.load(new File(".", "repositories.xml"););

			int nRepositories = conf.getMaxIndex("Repository");
			for (int i = 0; i <= nRepositories; i++)
			{
				String instance = "Repository(" + i + ")";
				String type = conf.getString(instance + ".type");
				String workspaceName = conf.getString(instance + ".workspaceName");
				String username = conf.getString(instance + ".username");
				char[] password = null;
				String temp = conf.getString(instance + ".password");
				if (temp != null)
					password = temp.toCharArray();

				// Dump details
				out.println("workspaceName = " + workspaceName);
				out.println("type = " + type);
				out.println("username = " + username);
				if (password != null)
					out.println("password = " + new String(password));
			}
		}
		catch (ConfigurationException e)
		{
			System.out.println("ERROR: " + e.toString());
		}
	}
}}}
