Testing EntityReferences in Xml

This Example gives you the way to test EntityReferences in an XML file. JAXP (Java API for XML Processing) is an interface which provides parsing of xml documents. There are some of the methods used in code given below for Testing EntityReferences in Xml File:-

XMLInputFactory Factory = XMLInputFactory.newInstance():-By this method we create a new instance of the factory.

factory.setProperty(XMLInputFactory.IS_COALESCING, true):-This method sets the property that requires the parser to coalesce adjacent character data sections.

factory.setProperty(XMLInputFactory.IS_REPLACING_ENTITY_REFERENCES, true):-This method sets the parser to replace internal entity references with their replacement text.

XMLStreamReader reader = Factory.createXMLStreamReader(new FileInputStream(file)):-Creates a new StreamReader which allows forward, read-only access to XML.

Xml code for the program generated is:-

<?xml version="1.0" encoding="UTF-8"?>
