public abstract class XmlParser
extends java.lang.Object

A simple XML parser that can be used quite similarly to the SAX parser but is based on the pull parser. It has two convenience methods. You can get the parent element via getParentName and you can get the text in the current node (in onEndElement) via getText. It is not very generic but generic enough for the purpose of this project
