java.lang.Object
  de.cbse.jeasy.JESimpleParser

public class JESimpleParser
extends java.lang.Object

Some simple methods to parse a string in XML format.
The methods use no SAXParser but some native string functions instead.
Its faster than to use a SAXParser.

See a demonstration in the program JEasyExample tab "Adress Form".
