解析 table 的内容

Question

我很难弄清楚为什么这不起作用。 URL 是这样的： https://www.cmlviz.com/pivot-points/GOOG

我想用复选框解析 table，它的 class 名称是 "updatable"，ID 是 "pivot_data_grid"。我究竟做错了什么？这真让我抓狂！我只想获取 table 中每一行的值以及标题（例如：5 天指数移动平均线）。感谢您的帮助

        string url = "https://www.cmlviz.com/pivot-points/{symbol}".Replace("{symbol}", symbol);

        HtmlDocument htmlDoc = new HtmlDocument();
        htmlDoc.LoadHtml(url);
        //var nodes = htmlDoc.DocumentNode.SelectNodes("//div[@id=pivot_data_grid]/table");
        var table = htmlDoc.DocumentNode.SelectNodes("//div[@class='updatable']");
        var table = htmlDoc.DocumentNode.SelectSingleNode("//div[@class='updatable']/table");

Answer 1

from bs4 import BeautifulSoup
import requests

r = requests.get(
    "https://www.cmlviz.com/inc/pivot-points.php?ticker=GOOG&key=57f42fb7382e7ef5679277fb3c2431c1")


soup = BeautifulSoup(r.text, 'html.parser')

for item in soup.findAll("div", {'class': 'updatable'}):
    print(item.get_text("\n", strip=True))

输出：
