xml is not a semantic language, there are no set tags to use as you make up your own tags, the only basic structure is you have beginning and end tags, for example begining tag for an xml file would be <xml> and the end tag would be </xml>.
Some programs require XML-structured data. But there are ways around that, so if you know that programs do not need XML-structured data, then no -- you do not need XML.
XML was designed for exchanging information. It is extensible, and easily constructed, since there are no restrictions on what you can use for a tag name (unlike HTML, for example). XML data is structured in a hierarchy which can be traversed like a database. It is a very common format and means of data exchange. There are several known standards for describing how data is exchanged, and XML is a very flexible means of doing that. If an application did not use XML for data exchange then the exchange would be through a proprietary format, which would not be as flexible or portable as XML.
XML provides a way for structured documentation. It is a software and hardware independent tool for carrying information. It is self-descriptive and has been designed for transportation and storage of data. It also facilitates dynamic data content for a web page.
Yes, XML can be used for data storage. XML store data in the form of nodes and sub-nodes.
XML uses XSL to describe data
An example of an information language is XML (Extensible Markup Language). XML is a markup language that is used to store and transport data in a structured format, making it easy for different systems to share and interpret information.
XML (apex)
xml is not a database, its a markup language that is used to transport data, information or bits of data are kept within xml tags and carried over the internet.
In xml, an element is a piece of data.
xml uses tags to describe data, any computer can then read the data using the tags.
xml is used on webpages and web services and can also be used to create data bases and to store and carry data.
XML is a language used to store data. XSLT is a language which is used to transform XML into other XML.
