Chapter being cut

[WarLock03]

Hello sir/ma'am... Is the library can't get all chapter data? because when I get chapter data/content using

TOCReference selectedChapter = tocReferences.get(0);
String chapterHref = selectedChapter.getCompleteHref();
loadChapterData(chapterHref);

then load it using

private void loadChapterData(String href){
Resource resource = book.getResources().getByHref(href);

if(resource != null){
String mimeType = resource.getMediaType().getName();
if("application/xhtml+xml".equals(mimeType) || "text/html".equals(mimeType)){
String content = new String(resource.getData(), StandardCharsets.UTF_8);
}
}
}

When i get the data from content, it does not load all chapter data. It got cut off specially when there's an image that supposed to display next to text and chapter like illustration display only single image
