Not entirely sure whether it would work but i guess you can take a parser like http://jsoup.org/ and use it as follows: 不确定是否能正常工作，但我想您可以使用http://jsoup.org/这样的解析器，并按如下方式使用它：
File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");
Elements chapters = doc.select("h2");
you then have to extract the content of the element and persist it as a new HTML file (including body, etc) 然后，您必须提取元素的内容并将其保存为新的HTML文件（包括正文等）

Finally i'm able to do it here is the solution to split html as per my need in the question 最后，我能够做到这一点，这是根据我在问题中需要拆分html的解决方案
public class App {
public static void JsoupReader(){
File input = new File("src/resources/sample_book.htm.html");
try {
Document doc = Jsoup.parse(input, "UTF-8");
Element head = doc.select("head").first();
Element firstH2 = doc.select("h2").first();
Elements siblings = firstH2.siblingElements();
String h2Text = firstH2.html();
List<Element> elementsBetween = new ArrayList<Element>();
for(int i=1;i<siblings.size(); i++){
Element sibling = siblings.get(i);
if(!"h2".equals(sibling.tagName())){
elementsBetween.add(sibling);
}else{
processElementsBetween(h2Text, head, elementsBetween);
elementsBetween.clear();
h2Text = sibling.html();
}
}
if (! elementsBetween.isEmpty())
processElementsBetween(h2Text, head, elementsBetween);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
private static void processElementsBetween(String h2Text,Element head,
List<Element> elementsBetween) throws IOException {
File newHtmlFile = new File("src/resources/"+h2Text+".html");
StringBuffer htmlString = new StringBuffer("");
htmlString.append("<html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"en\">");
htmlString.append(head);
htmlString.append("<body>"
+"<div class=\"c2\">"
+"<br/>"
+"<br/>"
+"<br/>"
+"<br/>"
+"</div>");
System.out.println("---");
for (Element element : elementsBetween) {
htmlString.append(element.toString());
}
htmlString.append("</body></html>");
FileUtils.writeStringToFile(newHtmlFile, htmlString.toString());
}
