public class PropertyUtilities

extends java.lang.Object

Utilities for converting property values that are org.w3c.dom.Element objects into other objects.

The methods assume that Property.getValue returns a org.w3c.dom.Element that corresponds to an XML fragment with a single root element and that the child of this element (whether it be an element or a text node is the desired value).

For example, the property value <name>MyValue</name> will be converted into MyValue by the method getAsString.
