SGML entity

Index SGML entity

In the Standard Generalized Markup Language (SGML), an entity is a primitive data type, which associates a string with either a unique alias (such as a user-specified name) or an SGML reserved word (such as #DEFAULT). [1]

Character encoding

Character encoding is used to represent a repertoire of characters by some kind of encoding system.

Data type

In computer science and computer programming, a data type or simply type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data.

Declaration (computer programming)

In computer programming, a declaration is a language construct that specifies properties of an identifier: it declares what a word (identifier) "means".

Declarative programming

In computer science, declarative programming is a programming paradigm—a style of building the structure and elements of computer programs—that expresses the logic of a computation without describing its control flow.

Document type declaration

A document type declaration, or DOCTYPE, is an instruction that associates a particular SGML or XML document (for example, a webpage) with a document type definition (DTD) (for example, the formal definition of a particular version of HTML1.0 - HTML 4.0).

Document type definition

A document type definition (DTD) is a set of markup declarations that define a document type for an SGML-family markup language (SGML, XML, HTML).

List of XML and HTML character entity references

In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.

Literal (computer programming)

In computer science, a literal is a notation for representing a fixed value in source code.

Mnemonic

A mnemonic (the first "m" is silent) device, or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory.

Numeric character reference

A numeric character reference (NCR) is a common markup construct used in SGML and SGML-derived markup languages such as HTML and XML.

New!!: SGML entity and Numeric character reference · See more »

Object (computer science)

In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.

New!!: SGML entity and Object (computer science) · See more »

Parameter (computer programming)

In computer programming, a parameter (often called formal parameter or formal argument) is a special kind of variable, used in a subroutine to refer to one of the pieces of data provided as input to the subroutine.

Plain text

In computing, plain text is the data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (images, etc.). It may also include a limited number of characters that control simple arrangement of text, such as line breaks or tabulation characters.

Primitive data type

In computer science, primitive data type is either of the following.

Reserved word

In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use".

Standard Generalized Markup Language

The Standard Generalized Markup Language (SGML; ISO 8879:1986) is a standard for defining generalized markup languages for documents.

String (computer science)

In computer programming, a string is traditionally a sequence of characters, either as a literal constant or as some kind of variable.

Uniform Resource Identifier

A Uniform Resource Identifier (URI) is a string of characters designed for unambiguous identification of resources and extensibility via the URI scheme.

Universal Coded Character Set

The Universal Coded Character Set (UCS) is a standard set of characters defined by the International Standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings.

XML

In computing, Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.

XML external entity attack

An XML External Entity (XXE) attack is a type of computer security vulnerability typically found in Web applications.
