Below is the code of extracting some value value using vtd-xml.

import com.ximpleware.*;

public class extractValue{
    public static void  main(String s[]) throws VTDException, IOException{
        VTDGen vg = new VTDGen();
        if (!vg.parseFile("input.xml", false));
        VTDNav vn = vg.getNav();
        AutoPilot ap = new AutoPilot(vn);
        ap.selectXPath("/aa/bb[name='k1']/value");
        int i=0;
        while ((i=ap.evalXPath())!=-1){
            System.out.println(" value ===>"+vn.toString(i));
        }   
    }
}
