Java – Reading XML file

by

One of the possible implementations:

File file = new File("userdata.xml");
DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
        .newInstance();
DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.parse(file);
String usr = document.getElementsByTagName("user").item(0).getTextContent();
String pwd = document.getElementsByTagName("password").item(0).getTextContent();

when used with the XML content:

<credentials>
    <user>testusr</user>
    <password>testpwd</password>
</credentials>

results in "testusr" and "testpwd" getting assigned to the usr and pwd references above.
