Parsing is the term used when a computer translates a complex, human-readable sentence or string into something it can use For example, Turning HTML from <HTML></HTML> to #42#43 (or whatever it might use) would be considered parsing Traditionally the conversion of a sentence from "Green is Blue" to NOUN VERB NOUN would be considered parsing, but I'm calling that "Tokenizing" (also another word for it) and by parsing I'm refering to translating the gramar
Syntactical analysis The process of finding the syntactical structure associated to an expression The syntactical structure of an expression is useful to recognize the relationship among the different elements of an expression and to assert its validity
the process or result of making a syntactic analysis (*) (+) parser: tool (often automatic or semi-automatic computer program) used for parsing ( General Description of Parsers - external link) parsed corpus: a corpus that have been syntactically analysed and provided with annotation representing the analysis
Parsing data refers to the process by which programming data input is broken into smaller, more distinct chunks of information that can be more easily interpreted and acted upon
Parsing may be divided into parts: lexical analysis and semantic parsing Lexical analysis divides strings into components based on punctuation or tagging Semantic parsing then attempts to determine the meaning of the string
We say that Emacs parses words or expressions in the text being edited Really, all it knows how to do is find the other end of a word or expression See section The Syntax Table
Parsing is the act whereby a document is scanned, and the information contained within the document is filtered into the context of the elements in which the information is structured
The process of checking an SGML formatted document to ensure it has met all the rules of both SGML and the DTD that is being used Technically, a document is not considered to be SGML until it has been successfully parsed, as defined by the ISO Standard for SGML (See also SGML, DTD)
An SGML parser is a computer application that breaks down an SGML-coded document into a series of logical elements and checks that these elements conform to the model defined in the associated document type declaration When parsing a document, the SGML parser: Checks each new character to see if it is part of a general delimiter string that identifies the start of a piece of markup Checks whether or not the character is a short reference delimiter that needs to be expanded Checks if the character is a separator character that should be ignored Identifies the various markup tags, identifying any entities that need to be expanded or recalled from external sources Checks if identified markup tags are valid according to the declared model
Usually applied to the action of a compiler in analyzing a program source file for syntax errors It is also used more widely to mean the analysis of the structure of input
We say that certain Emacs commands parse words or expressions in the text being edited Really, all they know how to do is find the other end of a word or expression See section 28 6 The Syntax Table
