DleseXMLReader (jOAI Java Documentation v3.3)

java.lang.Object
- org.dlese.dpc.xml.maps.DleseXMLReader

All Implemented Interfaces:

XMLMap
```
public class DleseXMLReader
extends java.lang.Object
implements XMLMap
```
This class provides mapping between DLESE metadata values and the corresponding XML metadata record.
The accessor methods act as an interface with the XMLNode and XMLRecord classes. The XML processing details are handled by those classes, but the one requirement of this class is to have knowledge of the paths structure. Paths are used as keys into the XMLRecord map.
