Jericho HTML Parser is an open source Java library allowing analysis and manipulation of parts of an HTML document, including server-side tags, while reproducing verbatim any invalid or unrecognized HTML.
Jericho HTML Parser also provides high-level HTML form manipulation functions.

Main features:
- - The presence of badly formatted HTML does not interfere with the parsing of the rest of the document, which makes the library ideal for use with "real-world" HTML that chokes other parsers.
- - PHP, JSP, ASP, PSP and Mason server tags are explicitly recognized by the parser. This means that normal HTML is still parsed properly even if there are server tags inside them, which is common for example when dynamically setting element attributes.
- - It is neither an event nor tree based parser, but rather uses a combination of simple text search, efficient tag recognition and a tag position cache. The text of the whole source document is first loaded into memory, and then only the relevant segments searched for the relevant characters of each search operation.
- - Compared to a tree based parser such as DOM, the memory and resource requirements can be far better if only small sections of the document need to be parsed or modified. Incorrect or badly formatted HTML can easily be ignored, unlike tree based parsers which must identify every node in the document from top to bottom.
- - Compared to an event based parser such as SAX, the interface is on a much higher level and more intuitive, and a tree representation of the document element hierarchy is easily created if required.
- - The begin and end positions in the source document of all parsed segments are accessible, allowing modification of only selected segments of the document without having to reconstruct the entire document from a tree.
- - The row and column number of each position in the source document are easily accessible.
- - Provides a simple but comprehensive interface for the analysis and manipulation of HTML form controls, including the extraction and population of initial values, and conversion to read-only or data display modes. Analysis of the form controls also allows data received from the form to be stored and presented in an appropriate manner.
- - Custom tag types can be easily defined and registered for recognition by the parser.
- - Built-in functionality to extract all text from HTML markup, suitable for feeding into a text search engine such as Apache Lucene.
- - Built-in functionality to render HTML markup with simple text formatting.
- - Built-in functionality to format HTML source code that indents elements according to their depth in the document element hierarchy.
- - Built-in functionality to compact HTML source code by removing all unnecessary white space.

I have taken Doug Holtons free Expat plugin, added Windows support, fixed a bug that would cause a crash when memory was low, improved access to Attributes, and enabled (local) entity resolving and XML Parser (Expat) Plugin was born.
It comes with a little demo project and with Dougs original documentation.
Enhancements:
- Fixed memory leak: The attribute objects were leaking
- Comments and hopefully all other parsed data will not contain LFs (chr(10)) any more but have them all converted into CRs (chr(13)), which is the usual line break character in RB.

XML Parser is a class that will read your iTunes XML file and parse the songs and song properties into memory where they can be manipulated by the programmer.

Completly freeware for non-commercial use.

Psychomancer is a text-based adventure/RPG game.
Welcome to Torenheim, the latest of a plethoria of fantasy realms. Magic, known as the Essence, runs as freely as air and water in this world. Warlocks and wytches have dedicated their studies to mastering and controlling the Essence. Psychomancer features Myrlandria, an initiate wytch.
Psychomancer is an adventure/RPG game, somewhat in the same flavor as Sierra On-lines Quest for Glory games. In its current incarnation, it is a text based game, fused with the air of nostalgia of the parser games from 20 years ago.
Select one of the four magical disciplines (Sorcery, Elementalism, Psychomancy, Spirit) to help your sorceress, Myrlandria, escape from the Angwyn Cult temple. Puzzles will result in different solutions, depending on which discipline you decide to follow.
This is just a small sample of what the real game will be like, except the final product will be a full fledged game with graphics, sound, and Sacred Kewpie Dolls. The full version of Psychomancer will be done when it is done, which might take until year 2010.
Enhancements:
- Input text is no longer case sensitive.
- Additional text and descriptions were added.
- Spells can be viewed by typing SPELLS in any room.
- Linux, Digital UNIX, Mac OS X, and Windows versions have been made available, in addition to the version for Mac OS 8 and 9.
- Saving no longer is functional in version 1.06. The Save Feature will be fully implemented in Version 1.1. If you have older save games (Versions 1.00 - 1.05), you can use them to restore old games. The save feature was removed since it is not fully complete and has been removed until a future release of Psychomancer.

ANTLRWorks 1.3b brings users a novel grammar development environment for ANTLR v3 grammars, which combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-agnostic debugger for isolating grammar errors. ANTLRWorks allows users to edit, visualize, interpret and debug any ANTLR 3 grammar through an easy-to-use graphical user interface.

ANTLRWorks helps eliminate grammar nondeterminisms, one of the most difficult problems for beginners and experts alike, by highlighting nondeterministic paths in the syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars more accessible to the average programmer, improve maintainability and readability of grammars by providing excellent grammar navigation and refactoring tools, and address the most common questions and problems encountered by grammar developers

Major Features:

1. Editor
   • Single window editing
   • Syntax highlighting
   • Rule navigation tree
   • Jump to rule or token definition
   • Go To Rule
   • Find usages of tokens or rules
   • Find and Replace using regular expression
   • Sensitive keyword, rule, and token auto-completion
   • Rules and actions folding
   • Tips and ideas
   • Auto-indentation
   • Refactoring - remove left recursion, extract or inline rule, etc.
   • Show generated lexer or parser code using syntax coloring
   • Syntax diagram display for lexer and parser rule
   • Show unreachable alternative(s) in syntax diagram
   • Display nondeterminism warning as ambiguous paths through the syntax diagram
   • Highlight decision DFA
   • Rule dependency graph
   • Export syntax diagram, NFA and parse tree to bitmap image or EPS file
   • Perforce integration
   • emacs key bindings (Mac OS X only)
   • Contextual menus
   • Print
2. Grammar interpreter
   • Dynamically interpreter any input text
   • Display parse trees as list or graph
3. Grammar debugger
   • Local or remote debugger
   • Language agnostic
   • Dynamic parse tree
   • Dynamic AST
   • Tree grammar debugging
   • Lookahead highlighting
   • Breakpoint in grammar
   • Breakpoint in input text!
   • Breakpoint on any events - LT, consume token, exception, etc.
   • Step over rule
   • Show corresponding grammar location and parse tree node for each input token
   • Detachable panels
4. Code generation:
   
   • ANTLRWorks supports code generation in any language that ANTLR knows how to generate via the output=language option.
   • For Java, however, ANTLRWorks knows how to build a test harness, compile everything, launch the parser, and connect to it--a great rapid prototyping feature when you can't use the interpreter because actions and/or semantic predicates must execute.

Enhancements:

• New Grammar Wizard
• StringTemplate Editor
• Custom test rig
• Run an input directly on the grammar

Requirements: Java 1.5 or later
