Chapter 3. Processing XML 59
Figure 3-3 SAX application components
To understand how an event-based API can work, consider the sample document
in Example 3-1.
Example 3-1 Sample XML document
<?xml version="1.0" encoding="UTF-8"?>
<Customer>
<name>Mary Smith</name>
<membership>10001</membership>
</Customer>
An event-based interface will break the structure of this document down into a
series of linear events, such as those shown in Example 3-2.
Example 3-2 Sample event breakdown
start document
start element: Customer
start element: name
characters: Mary Smith
end element: name
start element: membership
characters: 10001
end element: membership
end element: Customer
end document
