Returning the Output

When you run the Filter example, the MyStreamFilter class is compiled, and the XML stream is parsed as events and returned to STDOUT. For example, an Author event is returned as follows:

EVENT TYPE(1):START_ELEMENT
HAS NAME: Author
HAS NO TEXT
HAS NO ATTRIBUTES
-----------------------------
EVENT TYPE(2):END_ELEMENT
HAS NAME: Author
HAS NO TEXT
-----------------------------

Similarly, a Cost event is returned as follows:

EVENT TYPE(1):START_ELEMENT
HAS NAME: Cost
HAS NO TEXT

HAS ATTRIBUTES:
 ATTRIBUTE-PREFIX:
 ATTRIBUTE-NAMESP: null
ATTRIBUTE-NAME:   currency
ATTRIBUTE-VALUE: USD
ATTRIBUTE-TYPE:  CDATA

-----------------------------
EVENT TYPE(2):END_ELEMENT
HAS NAME: Cost
HAS NO TEXT
-----------------------------
