对于图像，我尝试了以下 jsoup 代码:
Elements img = doc.getElementsByTag("img");
for (Element el : img) {
System.out.println("Image Found!");
System.out.println("src attribute is : "+el.attr("src"));
}
但它什么也没有返回。我也不知道如何继续提取描述:
<br><font size="-1">NEW DELHI: Putting the Ufa process back on track India and Pakistan on Wednesday signaled process of reducing tensions by announcing Comprehensive Bilateral Dialogue to be led by Foreign Secretaries and prepared the ground for a visit by Prime&nbsp;...</font>
请帮我解决这个问题。
最佳答案
试试这段代码。请注意，RSS 提要是直接使用 Jsoup 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());
}
}
}
示例输出
