Marked Up Languages on Electronic Documents

Markup language (HTML, DHTML, XML) was developed by Tim Berners-Lee in 1990. HTML is an abbreviation for hypertext markup language, in particular the language used to create electronic documents on the World Wide Web. The hyperlink's landing page. All web pages displayed on the Internet that contain this include HTML code that helps to format and display text and images for readability. Without HTML, the browser does not know how to format the page and displays only plain text in a format that does not contain links.

Extensible Markup Language (XML) is an Internet-based language format for documents containing structured information or data. The Internet Markup Language is a mechanism for identifying the structure of a document. The XML specification defines a standard way to add tags to documents. Structured information includes content (words, pictures, etc.) and some instructions on the behavior of the content (for example, the content of the title has a different meaning than the content of the footnote, meaning that the contents of the title and the contents of the database table It is different)). XML is designed to describe data / information, document tags are user defined. XML is a cross platform, software, and hardware independent tool for transferring data and information. It is important to emphasize that XML is not an alternative to HTML, but complements Hypertext Markup Language (HTML). Although XML is designed to describe data / information, HTML is used to format and display data / information.

A structured document is an electronic document whose content is organized into marked blocks using markup languages ​​(such as HTML and XML) according to specific restrictions (called patterns). Structured documents take precedence over logically grouping information rather than formatting the presentation as an end user. When used under appropriate circumstances, it will be easier to search, update, and reuse the contents of the document. However, many companies feel that structured documents are inefficient and not worth implementing.

To understand the roots as a markup language document, it is very important to understand XML. The term trademark is an element in a document that is not part of the printed matter. In electronic document processing, the markup language is a formal description of the content contained in the document, which part is the brand and which part is the representative of the brand. In addition to providing logical isolation from the database system that evolved from the physical processing of the file, the markup language specification was developed from instructions indicating how to print part of the document. Such functional brands allow documents to have different formats. Various situations You can also set up a unified format for various parts of long documents and various pages of large websites. Brand work also helps to automatically extract important parts of documents. For markup language families containing XML, use markup enclosed in angle brackets.
