Definition

XML parsing is the process of reading an XML document and providing an interface to a user application for accessing the document. An XML parser is a software apparatus that accomplishes such tasks. In addition, most XML parsers check the well-formedness of the XML document and many can also validate the document with respect to a DTD (Document Type Definition) or XML schema. Through the parsing interface, the user application can focus on application logic itself, without dwelling on the details of XML.

There are mainly two categories of XML programming interfaces – DOM (Document Object Model) and SAX (Simple API for XML). DOM is a tree-based interface that models an XML document as a tree of nodes, via which an application can search for nodes, read their information, and update the contents of the nodes. SAX is an event-driven interface. The application registers with the parser various event handlers. As the parser reads an XML document, it generates events for the...
