Create a org.w3c.dom.Document reference to the xml file, using this method:
public static Document filepathToDocument(final String filepath){
Then, you can pretty much do anything like use XPath to navigate or simply get the list of Nodes:
XPath xPath = XPathFactory.newInstance().newXPath();
public static Document filepathToDocument(final String filepath){
Document doc = null;
File file = new File(filepath);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder;
try {
dBuilder = dbFactory.newDocumentBuilder();
doc = dBuilder.parse(file);
} catch (ParserConfigurationException | SAXException | IOException e) {
e.printStackTrace();
}
return doc;
}
Then, you can pretty much do anything like use XPath to navigate or simply get the list of Nodes:
XPath xPath = XPathFactory.newInstance().newXPath();
NodeList nodeList = (NodeList) xPath.compile("//"+elemName).evaluate(doc, XPathConstants.NODESET);
// or
NodeList nodeList = doc.getElementsByTagName(elemName);
// see www.w3schools.com to learn how to write xpath syntax.
