# HTML Parser 1.4

The HTML Parser Libraries.

See:
Description

Main Package
org.htmlparser | The basic API classes which will be used by most users when working with the html parser (the Parser class is the most important one in this).

Example Applications
org.htmlparser.lexerapplications.tabby | The Tabby program is a demonstration of how to use the underlying Lexer classes to perform file I/O.
org.htmlparser.lexerapplications.thumbelina | Extract the images behind thumbnail images.
org.htmlparser.parserapplications | Developers and users alike should try out the applications in this package.

Tags
org.htmlparser.tags | The tags package contains tag types that are created mostly by the scanners.

Lexer
org.htmlparser.lexer | The lexer package is the base level I/O subsystem.
org.htmlparser.lexer.nodes | The nodes package are the lexemes returned by the base level I/O subsystem.

Scanners
org.htmlparser.scanners | The scanners package contains classes responsible for the tertiary identification of tags.

Beans
org.htmlparser.beans | The beans package contains Java Beans that can integrate within IDEs.

Patterns
org.htmlparser.filters | The filters package contains example filters to select only desired nodes.
org.htmlparser.nodeDecorators | The nodeDecorators package contains classes that use the Decorator pattern.
org.htmlparser.visitors | The visitors package contains classes that use the Visitor pattern.

Utility
org.htmlparser.util | Code which can be reused by many classes, is located in this package.
org.htmlparser.util.sort | Provides generic sorting and searching.

# The HTML Parser Libraries.

These java libraries provide access to the contents of local or remote HTML resources in a programatic way.

## Components

The HTML Parser distribution is composed of:

- a low level `lexer` that converts characters into tags
- a high level `parser` that provides a heirarchical document view
- several example applications

## Building

To build the system you'll need to get the sources from the HTML Parser project on Sourceforge if you haven't already, and then follow the build instructions.

## Outstanding Issues.

Bugs are by far, the highest priority issues. Various reports of bugs related to the HTML Parser is available from the Bug Tracker on SourceForge. Issues related to incorrect behaviour of the current parser should be logged and tracked using this mechanism. Please use task lists and enhancement requests for issues that would not be considered bugs.

Several task lists are used to track the items that are not percieved as bugs, but are viewed by developers as things that need attention. The following list summarizes the purpose and target issues for each list.

- Applications - Work associated with the sample applications included with the HTML Parser download is tracked by this list. This would also include proposals for other example applications.
- Release - Work to be done before a major release is tracked by this list. Items included here must be resolved before the major release is considered complete. This can include refactoring, code clean-up, out-of-the-box experience work, build process fixes, platform (JDK) issues, performance or scalability enhancements, memory usage issues and other 'quality' issues that are not associated with a specific bug.
- API - Work needed to enhance or fix the parser API is tracked by this list. Standards compliance, additional classes, method signatures, changes to parameter types, refactoring, deprecation, new or enhanced constructors, and other programatic interface issues would fall into this category. This list should be limited to those changes that could impact the developer community that relies on existing behaviour from the parser.
- Documentation - Work associated with documenting the parser and it's example code and sample applications is tracked by this list. Javadocs, the web site and Wiki, Sourceforge site maintenance, mailing lists, forums, project documentation and other developer visible reference material would all fall under this category.

The Request For Enhancement list contains items that are proposed for future versions of the parser. Users may add to this list what they feel are extensions beyond simple bug fixing. Some user entered bugs are also transferred to this list if the scope of the fix would be too significant a change for the current version, or involve API changes that need to be vetted against the current user community.

## Mailing Lists.
