+ "</p></body></html>";
Elements paragraphs = doc.select("p");

有人可以用jsoup代码帮助我如何解析仅包含段落的部分，以便仅打印
can anyone help me with jsoup code how can i parse just portion including paragraph so that just print
Hello ,World!
Nothing is impossible
推荐答案
对于这小段html，您只需要做
For this small bit of html you just need to do
String html= "<html><head></head>" + "<body><p>Parsed HTML into a doc."+
+"</p></body></html>";
Document doc = Jsoup.parse(html);
Elements paragraphs = doc.select("p");
for(Element p : paragraphs)
System.out.println(p.text());
我看到您的链接包含几乎相同的html，然后您也可以将doc的定义替换为
As I see your link contains pretty much the same html you could then also replace the definition of doc with
Document doc = Jsoup.connect("https://tanmoy_mahathir.makes.org/thimble/146").get();
更新
这是完整的代码，可以编译并很好地运行.
Here is the full code that compiles and runs fine for me.
import java.io.IOException;
import java.util.logging.*;
import org.jsoup.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;
public class JavaApplication14 {
public static void main(String[] args) {
try {
String url = "https://tanmoy_mahathir.makes.org/thimble/146";
Document doc = Jsoup.connect(url).get();
Elements paragraphs = doc.select("p");
for(Element p : paragraphs)
System.out.println(p.text());
}
catch (IOException ex) {
Logger.getLogger(JavaApplication14.class.getName())
.log(Level.SEVERE, null, ex);
}
}
}
