Jsoup示例：打印URL的元数据

在此示例中, 我们将打印meta关键字和URL的描述。为此, 你需要调用Document类的select(), first(), get()和attr()方法。

import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
public class JsoupPrintMetadata {
	 public static void main( String[] args ) throws IOException{
			Document doc = Jsoup.connect("http://www.srcmini02.com").get();
			
			String keywords = doc.select("meta[name=keywords]").first().attr("content");
			System.out.println("Meta keyword : " + keywords);
			String description = doc.select("meta[name=description]").get(0).attr("content");
			System.out.println("Meta description : " + description);
}
}

输出：

Meta keyword : jsoup, tutorial, beginners, professionals, introduction, example, java, html, parser
Meta description : Jsoup tutorial for beginners and professionals provides html parsing facility 
in java with examples of printing title, links, images, form elements from url.
