XML- SAX Parser using JAXP API |
|
| |
(builds a DocumentBuilder).
TheDocumentBuilder further creates a DOMcompliant
document object.
The factory APIs enables to plug-in with the
XML implementation (provided by any vendor
without changing the source code). The obtained
implementation depends on the setting of the
system properties of these factory classes
javax.xml.parsers.SAXParserFactory and
javax.xml.parsers.DocumentBuilderFactory. The
default values (unless overridden at runtime)
point to the reference implementation.
In this section, you will learn how SAX Parser
parses and get the information from the XML
document.
The SAX Packages:
The SAX parser is defined in the following
packages:
Package |
Description |
org.xml.sax |
Defines the SAX interfaces. The name "org.xml" is the package prefix that was settled on by the group that defined the SAX API. |
org.xml.sax.ext |
Defines SAX extensions that are used when doing more sophisticated SAX processing, for example, to process a document type definitions (DTD) or to see the detailed syntax for a file. |
org.xml.sax.helpers |
Contains helper classes that make it easier to use SAX -- for example, by defining a default handler that has null-methods for all of the interfaces, so you only need to override the ones you actually want to implement. |
javax.xml.parsers |
Defines the SAXParserFactory class, which returns the SAXParser. Also defines exception classes for reporting errors. |
|
|
Try to avoid using attributes in few of the
situations.
Main classes of javax.xml.parsers package:
SAXParser |
Defines the API that wraps an XMLReader implementation class |
SAXParserFactory |
Defines a factory API that enables applications to configure and obtain a SAX based parser to parse XML documents |
Main interfaces of org.xml.sax package:
ContentHandler |
Receive notification of the logical content of a document. |
DTDHandler |
Receive notification of basic DTD-related events. |
EntityResolver |
Basic interface for resolving entities. |
ErrorHandler |
Basic interface for SAX error handlers. |
