Direct Known Subclasses:

public class XMLBasicReader

extends java.lang.Object

XMLBasicReader has two goals.

• It provides a way for parsing XML
• It provides a way for searching in this XML, without the need for an XPath implementation, and without the hassle of org.w3c.dom alone. It uses dots to lay a path in the XML (XPath uses slashes).
