Right-click on the project->Build Path->Configure Build Path->Add External JARs->Select the JAR file->click on Open button->Apply and Close. Step 6: Copy dom-2.3.0-jaxb-1.0.6.jar file and paste into the lib folder. Step 5: Create a lib folder in the project. Step 4: Download dom-2.3.0-jaxb-1.0.6.jar file: Click here. We have created the class file with the name ReadXMLFileExample1. Step 2: Create a class file and provide a class file name. Steps to Read XML File in Java Using eclipse ![]() Get Node by attribute value: If we want to search a node by the value of a specific attribute, we can use the getElementByTagName() method along with getAttribute() method.Get Node by text value: We can use getElementByTextValue() method in order to search for a node by its value.If we need to access all nodes from the starting, including the root node, we can recursively call the getChildElement() method. Where ELEMENT_NODE type refers to a non-text node which has sub-elements. Get all nodes: The getElementByTagName() method retrieves all the specific tag name from the XML file.Get root node: Document class provides the getDocumentElement() method to get the root node and the element of the XML file.Instantiate XML file: DOM parser loads the XML file into memory and consider every tag as an element.We must have followed the process to read an XML file in Java: DOM parser is slow in process and occupies lots of memory when it loads an XML file into memory. The node represents a component of an XML file. ![]() In DOM everything in an XML file is a node. It models an XML file in a tree structure for easy traversal and manipulation. DOM parser parses the entire XML file and creates a DOM object in the memory. We can create, delete, modify, and rearrange the node using the DOM API. The DOM API provides the classes to read and write an XML file. There are two parsers in Java which parses an XML file: Java provides many ways to parse an XML file. txt because XML file contains data between the tags. Reading XML file in Java is much different from reading other files like. Next → ← prev How to Read XML File in Java
