We can parse xml string by
getting a Document object.
public static Document loadXMLFromString(String xml) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = factory.newDocumentBuilder();
InputSource inputStream = new InputSource(new StringReader(xml));
return documentBuilder.parse(inputStream);
}
App.java
package com.sample.app;
import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
public class App {
public static Document loadXMLFromString(String xml) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder = factory.newDocumentBuilder();
InputSource inputStream = new InputSource(new StringReader(xml));
return documentBuilder.parse(inputStream);
}
public static void main(String[] args) throws Exception {
String xml = "<employee>\n" + " <firstName>Krishna</firstName>\n" + " <lastName>Gurram</lastName>\n"
+ "</employee>";
Document document = loadXMLFromString(xml);
NodeList nodeList = document.getChildNodes();
Node employeeNode = nodeList.item(0);
NodeList employeeChildNodes = employeeNode.getChildNodes();
System.out.println("Child nodes of '" + employeeNode.getNodeName() + "' node are : ");
for (int i = 0; i < employeeChildNodes.getLength(); i++) {
System.out.println(employeeChildNodes.item(i).getNodeName());
}
}
}
Output
Child nodes of 'employee' node are : #text firstName #text lastName #text
