这是HTML源代码,我必须从中提取值5390.85,5428.15,5376.15,5413.85.我想用jsoup来做这件事.但我对jsoup相对较新(今天我开始使用它).那我该怎么做呢？

URL url = new URL("http://www.nseindia.com/content/equities/niftysparks.htm");
Document doc = Jsoup.parse(url,3*1000);
String text = doc.body().text();

我已经使用jsoup提取了网站的内容.但如何提取我需要的值？提前致谢

我有一个jsoup中的文档,看起来像这样

Document doc = Jsoup.connect("http://en.wikipedia.org/").get();

我如何将其doc转换为字符串.

我正在使用JSoup进行身份验证,然后连接到网站.某些URL具有JSON响应(因为该站点的一部分是在AJAX中).JSoup可以处理JSON响应吗？

Connection.Response doc = Jsoup.connect("...")
                               .data(...)
                               .cookie(...)
                               .header(...)
                               .method(Method.POST)
                               .execute();
String result = doc.body()

在我的情况下,身体是"".

• 是因为JSoup不知道如何处理JSON？(当然没有)
• 或者因为我的请求中有错误？

是否有类似JSON的JSoup库？

它在HTTP上运行良好,但是当我尝试使用HTTPS源时,它会抛出以下异常:

我正在为一个班级制作一个小型Android应用程序,在那里我可以从美国癌症协会的网站上找到癌症相关事件.我一直在使用JSoup来获取有关事件的基本信息,并从我尝试使用select()方法的网站获取特定信息.但是,我正在使用的当前方法抓取的方式比我想要的更多HTML节点,我无法弄清楚原因.我试图抓住的表看起来像这样:

编辑:我意识到where id ="pnlResults"并没有在那个表结束,它在大约3个表之后结束,所有表都包含我想要获取的信息.这是表格

    <div id="pnlResults">

        <h2><span id="lblEventName">American Cancer Society 44th Annual Walter Hagen Golf Tournament</span></h2>
        <!-- General Information Box -->
        <div class="text-box boxed wide">
            <h3 class="head" style="width:97%;">
                General Information

            <div class="content">

我正在使用JSoup来解析来自http://www.latijnengrieks.com/vertaling.php?id=5368的内容.这是第三方网站,未指定正确的编码.我使用以下代码加载数据:

public class Loader {

    public static void main(String[] args){
        String url = "http://www.latijnengrieks.com/vertaling.php?id=5368";

        Document doc;
        try {

            doc = Jsoup.connect(url).timeout(5000).get();
            Element content = doc.select("div.kader").first();
            Element contenttableElement = content.getElementsByClass("kopje").first().parent().parent();

            String contenttext = content.html();
            String tabletext = contenttableElement.html();

            contenttext = Jsoup.parse(contenttext).text();
            contenttext = contenttext.replace("br2n", "\n");
            tabletext = Jsoup.parse(tabletext.replaceAll("(?i)<br[^>]*>", "br2n")).text();
            tabletext = tabletext.replace("br2n", "\n");

            String text = contenttext.substring(tabletext.length(), contenttext.length());
            System.out.println(text);


        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }    

}

这给出了以下输出:

我试图获取div类中包含的所有信息:bg_block_info,但我得到另一个div类的信息<div class="bg_block_info pad_20"> 为什么我弄错了？

Document doc = Jsoup.connect("http://www.maib.md").get(); 
Elements myin = doc.getElementsByClass("bg_block_info");

编辑:我的PROGUARD版本是4.7

今天我尝试jsoup (version 1.7.1)在我的Android应用程序中包含,但它给我带来了很多麻烦.每当我的应用程序面临强制关闭问题时,我导出已签名apk的proguard 打开,然后我禁用proguard并导出它apk并且它运行完美.请帮我.我该如何解决错误？堆栈跟踪如下:

我正在使用Jsoup库来读取URL.此网址包含几个<script>标记内的文字.我可以在每个<script>标签中获取文本吗？请注意,我并不是要求解析Javascript文件,因为我已经知道JSoup不允许这样做.URL的实际源代码在脚本标记中包含文本,我需要它.

doc = Jsoup.connect("http://www.example.com").timeout(10000).get();

Element div = doc.select("script").first();
for (Element element : div.children()) {
System.out.println(element.toString());
}

这是源代码中的一个脚本标记:

<script type="text/javascript">
(function() {
...
})();
</script>

String body = "<br>";
Document document = Jsoup.parseBodyFragment(body);
document.outputSettings().escapeMode(EscapeMode.xhtml);
String str = document.body().html();
System.out.println(str);

期望: <br />

结果: <br>

Jsoup可以将值HTML转换为XHTML吗？
