android - 如何从 HTML 中提取内容

Question

我有 HTML 作为字符串，我只想从中提取“post_titles”。这是 HTML 字符串:

<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>
<div class="comment_status">open</div>
<div class="ping_status">open</div>
<div class="_status">publish</div>
<div class="jj">20</div>
<div class="mm">07</div>
<div class="aa">2015</div>
<div class="hh">00</div>
<div class="mn">52</div>
<div class="ss">33</div>

这篇文章的标题是“单亲育儿”，这是我想提取的内容。这就是我正在使用的:

Elements link = doc.select("div[class=post_title]");
String title = link.text();

但这是给出一个空字符串。我也试过:

Elements link = doc.select("div[id=inline_49]").select("div[class=post_title]");
String title = link.text();

这也给出了一个空白字符串。请帮助我究竟需要使用什么选择器来提取标题。

您必须在您的请求中包含一个 cookie。检查此 Java 代码:

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();
        }
