	Parsing - Wikipedia, the free encyclopedia
		Generally, parsers operate in two stages, first identifying the meaningful tokens in the input, and then building a parse tree from those tokens.
		Parsers for programming languages tend to be based on context-free grammars because fast and efficient parsers can be written for them.
		Parsers are usually not written by hand but are generated by parser generators.

		Whenever a btyacc generated parser runs into a shift-reduce or reduce-reduce error in the parse table, it remembers the current parse point (yacc stack and input stream state), and goes into trial parse mode.
		Happy is a parser generator system for Haskell, similar to the tool `yacc' for C. Like `yacc', it takes a file containing an annotated BNF specification of a grammar and produces a Haskell module containing a parser for the grammar.
		Parser objects are composed through operator overloading and the result is a backtracking LL(inf) parser that is capable of parsing rather ambiguous grammars.

	JavaCC HTML Parser (Site not responding. Last check: 2007-11-07)
		The parser transforms an input stream into a parse tree; the elements of the parse tree are defined in HtmlDocument.
		HtmlFormat is an example program which uses the parser, the scrubber, and the collector to parse and pretty-print an HTML page and dump it to System.out.
		The parser tries to properly deal with quoted strings properly (so that things that look like tags or end-of-comment markers inside of quotes are not mistaken for tags), but sometimes quoted strings are improperly terminated, or an apostrophe will be interpreted as the start of a quoted string.

		However, the parser has a number of features that are either not covered in Allen's algorithm or that are extensions of it.
		Another interesting point is that for the moment this parser operates like a DCG in that the left-hand correlate of the right side of a rule must match exactly (this will be changed in the next version).
		The next version of this parser (through an easy fix) will allow that there may not be an exact match between left and right sides of rules (for example, will allow rule 1 to select rule 2) but will still exclude the possibility of rule 4 from selecting rule 3.

	Parser (Java 2 Platform SE v1.4.2)
		All SAX1 parsers must implement this basic interface: it allows applications to register handlers for different types of events and to initiate a parse from a URI, or a character stream.
		SAX1 parsers are reusable but not re-entrant: the application may reuse a parser object (possibly with a different input source) once the first parse has completed successfully, but it may not invoke the parse() methods recursively within a parse.
		SAX parsers are not required to provide localisation for errors and warnings; if they cannot support the requested locale, however, they must throw a SAX exception.

		The html-parser package is a variant language implementation of the Python's SGML parser (sgmllib.py), HTML parser (htmllib.py) and Formatter (formatter.py).
		In fact, it does not provide a full SGML parser -- it only parses SGML insofar as it is used by HTML, and the module only exists as a base for the HTMLParser class.
		The html-parser.rb defines a class HTMLParser which is a parser for HTML documents.

	Glossary of Parsing Terms
		A parser is a program, or more likely a procedure within a program, which scans a sequence of input characters or input tokens and accumulates them in an input buffer or stack as determined by a set of productions which constitute a grammar.
		A parser generator, such as AnaGram, is a program that converts a grammar, a rule-based description of the input to a program, into a conventional, procedural module called a parser.
		The tokens identified by a parser are concrete instances of the abstract tokens in the grammar.

	18.1 parser -- Access Python parse trees
		Most importantly, a good understanding of the Python grammar processed by the internal parser is required.
		The parser itself is created from a grammar specification defined in the file Grammar/Grammar in the standard Python distribution.
		Be aware that the values of the sequences which are considered ``correct'' will vary from one version of Python to another as the formal grammar for the language is revised.

	Apache Lucene - Query Parser Syntax - Apache Lucene
		If you are programmatically generating a query string and then parsing it with the query parser then you should seriously consider building your queries directly with the query API.
		In other words, the query parser is designed for human-entered text, not for program-generated text.
		An analyzer, which the query parser uses, is designed to convert human-entered text to terms.

	GOLD Parsing System - A Free, Multi-Programming Language, Parser
		As the information is analyzed by the scanner/tokenizer, a sequence of tokens, which represent the atoms of the source string, are created and passed to the parser.
		The parser then performs syntactic analysis on the token sequence and determines if it is structurally valid.
		Admittedly, this is not a particularly clever acronym, but it does, in part, represent the history of the greater Sacramento Area.

	Link Grammar
		The Link Grammar Parser is a syntactic parser of English, based on link grammar, an original theory of English syntax.
		As of December 2004, we are releasing the parser under a new license; the license allows unrestricted use in commercial applications, and is also compatible with the GNU GPL (General Public License).
		The parser is robust; it is able to skip over portions of the sentence that it cannot understand, and assign some structure to the rest of the sentence.

	Siber Systems BtYacc: BackTracking Yacc
		A C++ parser (for example) can just put a [YYVALID;] after every complete declaration and statement rule, corresponding to pruning the backtracking state after seeing a ';' or '}' -- there will never be a situation in which it is useful to backtrack past either of these.
		Variant parsers: Btyacc supports the -S flag to use a different parser skeleton, changing the way that the parser is called and used.
		The skeleton "push.skel" is included to produce a "passive" parser that you feed tokens to (rather than having the parser call a separate yylex routine).

	HTML::Parser - SGML parser class
		The return value is a reference to the parser object.
		The parser will make sure that it does not break a word or a sequence of spaces between two invocations of $self->text().
		There is really nothing in the basic parser that is HTML specific, so it is likely that the parser can parse other kinds of SGML documents.

		There are many log parsers available on the web, and each of them is a little different.

		After this parser had some success, I decided to revise the whole code, and to redesign the parser where it was needed.
		In general, the task of a XML parser is to read XML text, and to represent the text somehow in memory.
		The type of the class may be arbitrary (except three base methods which connect the object to the tree), and the parser has a mechanism to dynamically select the class of the object depending on the element type of the XML node.

		The parser treats \r and \r\n as \n.

		The new parser is completely independent and may safely be used in a separate thread.

	Essence, an LR parser generator for Scheme (Site not responding. Last check: 2007-11-07)
		The generated parsers perform error recovery, and are highly efficient.
		Rather, the parser generator results from a general parser which takes the input grammar as a parameter; no generation and recompilation is necessary to try out changes to a grammar.
		The generated parsers result from the general parser by an automatic program transformation called partial evaluation.
