Class SaxAuthor

java.lang.Object
eu.bandm.tools.util.SaxAuthor
public class SaxAuthor extends Object
Facade for conveniently creating sequences of SAX events, more likely to be well-formed.

For this, a stack is maintained of the currently open elements, and closing tags are checked for the correct sequence.
