Java SAX parser is a Java API that can be used to parse and modify XML documents. To modify any XML document using SAX parser, We have to store the data in any data structure because we cannot go back as it has only forward read-only access. In this chapter, we are going to see […]

Java SAX Parser is a read-only parser which is used to read the XML documents in a forward read-only manner. We cannot create XML documents using a SAX parser. It is better to use StAX parser for creating XML documents rather than using SAX parser. Please refer the Java StAX Parser section for the same.

Java SAX Parser is an API in java which can be used to query XML documents. To query large XML documents using event based APIs, we can use Java SAX parser API. The SAXParser API is present inside the javax.xml.parsers package. We can query any XML document by implementing the call back methods inside Handler […]

Java SAX(Simple API for XML) parser is an API in Java to parse XML documents. SAX parser is an event based parser and uses a Handler class to handle the events. The call back methods such as startElement(), characters(), endElement() etc., are implemented inside the Handler class to obtain the details of elements and their […]

Java SAX (Simple API for XML) is an event-based parser to parse XML documents. Unlike DOM parser, SAX parser does not create a parse tree. It will not load the entire document into memory, instead, it reads through the XML document and notifies the client program whenever it encounters elements, attributes, text content and other […]

Java DOM parser API provides methods to modify the already existing XML documents. We can add or remove elements and attributes, modify the text content of elements and attribute values using the methods of Java DOM parser. The setTextContent() method replaces the original text of elements, removeAttribute() removes the existing attributes and the setAttribute() method […]

Java DOM parser API has methods, interfaces and classes to create XML documents. Using this API, we can create XML documents from the scratch through our Java applications. The createElement() method creates new elements and the appendChild() method appends the created elements to already existing elements. Create XML Using Java DOM Parser We can create […]

Java DOM parser is an API in java to parse and query XML documents. Using Java DOM parser, we can query large XML documents to get insights about our data. Manually, it is not easy to check the entire XML document to obtain related information. We can query XML elements by their tag name using […]

Java DOM parser is a Java API to parse any XML document. Using the methods provided, we can retrieve root element, sub elements and their attributes using Java DOM parser. In this tutorial we have used the getTagName() method to retrieve the tag name of elements, getFirstChild() to retrieve the first child of an element and getTextContent() […]

Java DOM parser is an API (Application Programming Interface) that has classes, interfaces and methods to parse XML documents by creating DOM tree structure. The Document Object Model (DOM) is an official recommendation of the World Wide Web Consortium (W3C). It defines an interface that enables programs to access and update the style, structure, and […]
