is DTD for an XML document
DTD is the Document Type Definition for an XML document. It defines the
way in which the elements in an XML document should look like. The type
of data that should be present in the nodes, the number of child nodes
that should be present, the attributes that should be used for an element
are all defined in a DTD file.
on this the XML document is validated. If an XML document is created based
on this rule then it is said to be a valid document. All XML documents
are validated against a DTD or a schema.
schema is an advanced version of a DTD. Schemas are used now-a-days instead
of DTD as they have more flexibility in validating the XML documents.
'+', '*', and '?' are used to define the number of child nodes that should
be present within an element. The elements are defined using the ELEMENT
keyword. The attributes are defined using the ATTLIST keyword. The type
of data is either CDATA or PCDATA.
