The code of "Hello World" is as follows:
static void doXmlMarshal() throws Exception {
Statement s1 = new Statement("Hello, world!");
Concept c1 = new Concept("hello");
Concept c2 = new Concept(",");
Concept c3 = new Concept("world");
Concept c4 = new Concept("!");
Concept c5 = new Concept("H");
Concept c6 = new Concept("h");
Concept c7 = new Concept("e");
Concept c8 = new Concept("l");
Concept c9 = new Concept("o");
Concept c10 = new Concept("w");
Concept c11 = new Concept("r");
Concept c12 = new Concept("d");
Concept c13 = null;
s1.addConcept(c1, c2, c3, c4, c5); //No position of sub-concepts sample
s1.addConcept(c13); //NullPointerException tolerance sample
c1.addSubConceptWithPosition(c6, c7, c8, c9); //Auto positions of sub-concepts sample
c1.addSubConcept(); //NullPointerException tolerance sample
c3.addSubConcept(new Integer[] {7, 8, 9, 10, 11}, c10, c9, c11, c8, c12); //Manual positions of sub-concepts sample
c5.addIncompatibleAttribute("case", new Concept("Uppercase"));
c5.addCompatibleAttribute("case", new Concept("大写"));
BaseRelation br1 = new EquivalenceRelation(c5, c6);
//print out all the elements in XML mode
Root root = new Root(s1, br1, null); //NullPointerException tolerance sample
// root.removeElement(br1);
System.out.println();
root.marshalToXml(System.out);
}Output：
