How to use SemanticDecisionTable from an xml file?

get all columns from an XML file and pass the parameters into a vector of String array, or a String matrix [ ] [ ]

public static void getAllColumnsTest() {
    openSDTfile file = new openSDTfile();

    SemanticDecisionTable table = new SemanticDecisionTable(sdt);
    Vector<String[]> columns = table.getAllColumns();
    for (int i = 0; i < columns.size(); i++) {
        String[] array = columns.get(i);
        StringArray sa = new StringArray(array);
        sa.printArrayToConsole();
    }
    System.out.println(table.getProcessInfo());

}
