you try elements , children. started:
public void xmlparse(string xmlfile) throws parserconfigurationexception, saxexception,ioexception { documentbuilderfactory docbuilderfactory = documentbuilderfactory.newinstance(); documentbuilder docbuilder = docbuilderfactory.newdocumentbuilder(); document document = docbuilder.parse(new file(xmlfile)); xmlparse(document.getdocumentelement()); } private void xmlparse(element node) { nodelist nodelist = node.getchildnodes(); (int = 0; < nodelist.getlength(); i++) { node currentnode = nodelist.item(i); string value = currentnode.getnodename(); system.out.print(value + " "); // prints employee nodelist nodes = currentnode.getchildnodes(); (int j = 0; j < nodes.getlength(); j++) { node cnode = nodes.item(j); system.out.print(cnode.getnodename() + " ");//prints:name, id, age } system.out.println(); } } output is:
#text employee #text name #text id #text age #text #text employee #text name #text id #text age #text #text employee #text name #text id #text age #text #text
