XML Tutorials - Herong's Tutorial Notes

∟SAX (Simple API for XML) Programming Interface

∟SAX Parsing Pattern Example

This section provides a tutorial example on how to print out the SAX parsing pattern by SAXBrowser.java with a given XML file.

Now let's use another XML file, user.xml, with more elements to show the SAX parsing pattern:

<?xml version="1.0"?>
<user status="active">
 <!-- This is not a real user. -->
 <first_name>John</first_name>
 <last_name>Smith</last_name>
</user>

Ran java SAXBrowser user.xml, I got:

Starting document...
e_user
a_ status=active
c__
c__

c__
c__
c__

c__
e__first_name
c___John
c__
c__

c__
e__last_name
c___Smith
c__
c__

Ending document...

The program still works. But why the parser fired so many "characters()" events? It looks like the parser didn't group the space character, line feed, and cartridge return into a single char[] and fire one "characters()" event. It fired multiple events, one per character.

Notes and sample codes in this section are based on JDK 1.4.1_01.
