SectionList list = ppt.getSectionList();
String name = "";
ISlide indexSlide = null;
Integer[] indexSlideNumber = new Integer[list.getCount()];
String[] indexSlideName = new String[list.getCount()];
for(int i = 0; i< list.getCount(); i ++) {
name = list.get(i).getName();
//find section first page by SlideId
indexSlide = ppt.findSlide(Integer.parseInt(String.valueOf((list.get(i).getSlideIdList()).get(0))));
indexSlideNumber[i] = indexSlide.getSlideNumber();
indexSlideName[i] = name;
