Python 网页抓取 - 试图从 table 标签中获取数字
Python Web Scraping - trying to get numbers from table tags
难以从网页中提取我需要的一些数据。
这是我正在尝试的类型
from bs4 import BeautifulSoup
import urllib
url = 'http://www.myfxbook.com/community/outlook'
htmlfile = urllib.urlopen(url)
soup = BeautifulSoup(htmlfile)
for tag in soup.findAll('td'):
print tag
（这给出了数千行代码作为输出）
This is where the data that I need is held
我不知道如何让它足够具体
我需要 'td' 标签内的“5169 手”，同样需要“2879 手”再往下一点。
所以我真正想要的是显示 EURUSD 多头和空头手数的两个数字。
如有任何帮助，我们将不胜感激。
