Validating define xml
Extensible Markup Language (XML) is used to describe data.
The XML standard is a flexible way to create information formats and electronically share structured data via the public Internet, as well as via corporate networks. You will have to create tags according to your needs.
Validation in XML file against a DTD need a XML file and its DTD document. This DTD file defines all elements to keep in the XML file.
Xml Reader methods let you move through XML data and read the contents of a node. An XML document is considered to be well formed if it meets all the syntactical requirements defined by the W3C XML 1.0 Recommendation.XSD is a schema language; you use it to define the possible structure and contents of an XML format.A validating parser can then check whether an XML instance document conforms to an XSD schema or a set of schemas. You use the following settings on the Xml Reader Settings class to specify what type of validation, if any, the Xml Reader instance supports. Xml Reader doesn't support XML-Data Reduced (XDR) schema validation.
