Java Program To Parser An XML File Using DOM Parser

DOM Parser

DOM Stands For Document Object Model. It characterizes an interface to access process and style, structure and substance of XML reports

The DOM Parser gives functions of capacities to use the XML documents to inspect the substance and structure of the report. It also checks the proper format of the XML file.

Example Of DOM Parser

AIM:

To write a java program to parse an XML file using DOM parser.

PROCEDURE:

STEP 1: Create a XML document.

STEP 2: Create a java program with the DOM API.

STEP 3: Parse the XML document using the java program.

STEP 4: Display the contents of the XML document with appropriate levels.
