Class NodeletParser

java.lang.Object

com.aspectran.core.util.nodelet.NodeletParser

public class NodeletParser
extends java.lang.Object

The NodeletParser is a callback based parser similar to SAX. The big difference is that rather than having a single callback for all nodes, the NodeletParser has a number of callbacks mapped to various nodes. The callback is called a Nodelet and it is registered with the NodeletParser against a specific XPath.
