html file should be splitted !

Do you have any "criteria" on how we are supposed to split the HTML? An example would surely help. — Rey Libutan, Jan 16 '14 at 09:26

Your question is pretty vague :).

On splitting String(html in this case): The easiest was is to read in the html file as text into a String, then use String.split() method to split the string around the desired regex. For example .split("/div") will give you a crude approach where your html will be broken up into "divs" (supposed you even have divs in your html). However this will work badly for nested divs.

On reading/writing files: Reading a plain text file in Java Also you will find a hackload of html parser on the net that will most likely work ten times better in your case.

all my questions will non-natural :) will try it thanks – januprasad Jan 16 '14 at 09:52 — januprasad, Jan 16 '14 at 09:52

You can use the following logic ....   
List<String> lines = Files.readAllLines(FileSystems.getDefault()
                    .getPath("yourhtmlfile"),
                    StandardCharsets.UTF_8);    
            for (String htmlData : lines)
            {
                Pattern splitPattern = Pattern
                        .compile(sometext_pattern);
                Matcher match = splitPattern.matcher(htmlData);

                while (match.find())
                {    
                    String lineToBeSplit = match.group();    

                }

                            .
                            .

            }

"lineToBeSplit" will have the split data.
