XML | Computer Science
XML is a markup language used for storing and transporting data from source to client. It uses user-defined tags and is platform independent. Tools like XML editors, validators, and parsers are used to work with XML documents. XML focuses on describing data, while HTML focuses on displaying data, making XML well-suited for transporting data between systems. XHTML combines aspects of HTML and XML to create a stable markup language. SOAP uses XML to transport messages and data for web services, while REST can use XML, JSON, or plain text and is easier to maintain than SOAP.

- 2. XML is amarkup language which is used for storing the data and for transporting data from source to client. XML is independent of any predefined tags and also it is platform independent. Thus it helps in exchange of data and it a base language for many tools.
- 3. XML consists ofthe following components: 1. XML tags : tells the scope of an element. It can be a start tag, end tag or empty tag 2. Elements and attributes: component between start and end tag is an element. Element may further consists of attributes
- 4. 1. XML Editor: It is used to write, edit and read XML. 2. XML Formatter : It is used to format and correct the formatting errors in an XML making the file more readable. 3. XML Validators: It validates an XML document for XML syntax rules and the schema. 4. XML Parsers : It accesses and modify an XML. Examples of XML parsers are SAX parsers, DOM parsers and pull parsers.
- 5. XML and HTMLdiffer in the way they process data. HTML focuses on how data looks thus mostly used in designing of web pages. However, XML focuses of storage of data. It describes data and hence used for transporting data between two or more entities XHTML keeps the goods of both HTML and XML. It is a well written language making it a stable language.
- 6. SOAP is axml based protocol which is used for transporting messages and data for web services. It enables applications to connect to a remote procedure and communicate with it. REST is an architectural style which depends on another protocol to create web services. It not only supports XML but also supports json and plain text. REST is easy to maintain as compared to SOAP as there is no WSDL contract in between the client and server.
