Java 如何使用Jsoup从html数据中获取图像源和描述

我正在尝试解析atom提要，以使用RomeAPI提取提要。atom提要为我提供了content属性，该属性包含文章的图像和描述。 以下是atom提要的url:。 现在我想从内容部分提取图像和描述

但它什么也不返回。此外，我不知道如何继续提取描述：

请帮我解决这个问题。

试试这个代码。请注意，RSS提要是通过Jsoup直接获取的

Document news = Jsoup.connect("http://news.google.com/news/section?output=atom&ned=in&q=narendra%20modi").get();

int i=0;
for (Element entryContent : news.select("entry > content")) {
    System.out.format("\n## ENTRY %d\n", ++i);
    for (Element el : Jsoup.parse(entryContent.text()).select("img[src], tr td.j font[size]:nth-of-type(2)")) {

        String elementTagName = el.tagName();  

        if (elementTagName.equalsIgnoreCase("img")) {
            System.out.println("src attribute is : " + el.attr("src"));
        } else if (elementTagName.equalsIgnoreCase("font")) {
            System.out.println("description is : " + el.text());
        } else {
            System.out.println("Unexpected element >> " + el.html());
        }
    }
}

样本输出

在JSoup 1.8.3上测试

您可以使用ROME来提取条目（或使用jackson和xml插件）。然后获取每个条目的HTML内容，并使用JSoup解析它（转换和预先转换）。然后使用return HTML元素并搜索img标记以提取src-attribute。运行代码时会出现以下异常：线程中的异常“main”“org.jsoup.UnsupportedAdminTypeException:未处理的内容类型。必须是text/*、application/xml或application/xhtml+xml。Mimetype=application/atom+xml，URL=org.jsoup.helper.HttpConnection$Response.execute（HttpConnection.java:472）org.jsoup.helper.HttpConnection$Response.execute（HttpConnection.java:424）org.jsoup.helper.HttpConnection.execute（HttpConnection.java:178）org.jsoup.helper.HttpConnection.get（HttpConnection.java:167）@GarimaTripathi您使用的是哪个版本的JSoup？@GarimaTripathi或者，您可以调用

ignoreContentType（true）

来解决此问题。所以新闻可以像这样下载：

documentnews=Jsoup.connect（“http://news.google.com/news/section?output=atom&ned=in&q=narendra%20modi”）.ignoreContentType（true.get（）
Document news = Jsoup.connect("http://news.google.com/news/section?output=atom&ned=in&q=narendra%20modi").get();

int i=0;
for (Element entryContent : news.select("entry > content")) {
    System.out.format("\n## ENTRY %d\n", ++i);
    for (Element el : Jsoup.parse(entryContent.text()).select("img[src], tr td.j font[size]:nth-of-type(2)")) {

        String elementTagName = el.tagName();  

        if (elementTagName.equalsIgnoreCase("img")) {
            System.out.println("src attribute is : " + el.attr("src"));
        } else if (elementTagName.equalsIgnoreCase("font")) {
            System.out.println("description is : " + el.text());
        } else {
            System.out.println("Unexpected element >> " + el.html());
        }
    }
