XML is a cross platform tool or a language to gain data transfer between the cross platform. It is used to display the data in a formatted matter. It is used to represent the information or data and does not have any capability to perform any tasks on its own. It always requires an application in order to work with the XML documents.
Rules for writing a Well Formed XML- Extensible Markup Language document are: extension for the file should be XML, XML documents are case sensitive files and hence the tags and the attribute values of the documents should be maintained in proper case, XML document should have at least one root element which can have one or more Child elements. Whenever the XML document is designed based on the DTD file then it is said to be valid XML document.
Data Type Definitions: It is used to provide the definitions for the data to be used or to be provided in the XML document. Entity: It is used to define a user specific named entities which can be used in the XML document. When ever a named entity is used within a XML document then the value of the named entity will be substituted as a macro substitution within the XML document.
External DTD Binding, whenever the data type definitions are specified in a DTD file and if it has been explicitly binded to the XML document then it is said to be external DTD binding.
