저는 Java에서 초보자입니다. Jsoup 라이브러리를 사용하여 웹 사이트에서 읽을 자바 코드를 작성했습니다.웹 스크래핑에서 데이터 정렬 및 표시 Java
package view;
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
public class WebscrappingCls {
public WebscrappingCls() {
super();
}
public static void main(String[] args) {
String baseURL = "https://www.nseindia.com/live_market/dynaContent/live_watch/option_chain/optionKeys.jsp?segmentLink=17&instrument=OPTIDX&symbol=NIFTY&date=25JAN2018";
try {
Document doc = Jsoup.connect(baseURL).get();
String Title = doc.title();
System.out.println(Title);
Elements links = doc.select("th");
for (Element link : links) {
System.out.println("\nlink : " + link.attr("th"));
System.out.println("text : " + link.text());
}
Elements links1 = doc.select("td");
for (Element link : links1) {
System.out.println("\nlink : " + link.attr("td"));
System.out.println("text : " + link.text());
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
나는 쿼리에서 루프에 대한 첫 번째를 사용하여 헤더 데이터를 검색 할 수 있어요하지만 데이터가 아래 이미지에서 언급 검색 할 수 없습니다. 웹 사이트의
HTMLCode은 다음과 같다.
