eXtensible Markup Language - XML File Access

XML documents can be created in two different ways: a) With user defined tags b) With a template (xslt files) There are different parsers available to parse an XML file: e.g. a) DOM [Document Object Model] b) SAX 1) The parsers provide different API's to extract data from the XML File. 2) XML File is read as 'document' by the parser. 3) Each tags should have an opening and closing tag, that is called a Node. 4) A Node can have attributes and inner text. 5) Both Attributes and inner text provides data about the node.
