Solution 1:

You must include a cookie in your request. Check this Java code:

try {

            String url = "https://ssblecturate.wordpress.com/wp-login.php";

            Connection.Response response = Jsoup.connect(url)
                    .data("log", "your_login_here") // your wordpress login
                    .data("pwd", "your_password_here") // your wordpress password
                    .data("rememberme", "forever")
                    .data("wp-submit", "Log In")
                    .method(Connection.Method.POST)
                    .followRedirects(true)
                    .execute();

            Document document = Jsoup.connect("https://ssblecturate.wordpress.com/wp-admin/edit.php")
                    .cookies(response.cookies())
                    .get();

            Element titleElement= document.select("div[class=post_title]").first();
            System.out.println(titleElement.text());

        } catch (IOException e) {
            e.printStackTrace();
        }

Solution 2:

Try this, but make sure your HTML text is well formatted in the String :

String html ="<div class=\"hidden\" id=\"inline_49\">"+"<div class=\"post_title\">Single parenting</div>"+"<div class=\"post_name\">single-parenting</div>"+"<div class=\"post_author\">90307285</div>";

Document document =Jsoup.parse(html);
Elements divElements = document.select("div");
for(Element div : divElements) {
    if(div.attr("class").equals("post_title")) {
       System.out.println(div.ownText());
    }
}

Updated ! Hope It works for you :

//Get div tag with class name is 'post_title'Document doc;
    try {
        File input = new File("D:\\JAVA\\J2EE\\Bin\\Bin\\Project\\xml\\src\\demo\\index.html");
        doc =Jsoup.parse(input, "UTF-8", "http://example.com/");
        //Get div tag with class name is 'post_title'Element element = doc.select("div.post_title").first();
        System.out.println(element.html());
    } catch (Exception e) {
        e.printStackTrace();
    }

Solution 4:

If you have it in a String, you can try with regExp.

This regex means "everything between with class post_title (not exactly but yes for your sample).

String exp = "<divclass=\"post_title\">([^<]*)</div>"

You should be able to get the content with:

String post_title = Pattern.compile(exp).matcher(yourString).group(1);

NOTE: I guess your post_title does not contain "<"... This should indeed generate an XML structure error.
