我是网络刮擦的新手。

我正在尝试从

我的代码是：

import requests
from bs4 import BeautifulSoup as bs

url = 'https://www.dailyfx.com/sentiment'

all_pages_reviews = []
response = requests.get(url)
soup = bs(response.content, 'html.parser')

rev_div = soup.findAll("span",attrs={"class","dfx-rateDetail__percentageInfoText font-weight-bold"})

print(rev_div)

这给出了Rev_div为“ bs4.element.ResultSet”，以下输出：

</span>, <span class="dfx-rateDetail__percentageInfoText font-weight-bold" data-market-id="GBPUSD" data-sort-column="sentiment-long" data-stream-type="sentiment" data-type="long-value-info" data-value="--">

</span>, <span class="dfx-rateDetail__percentageInfoText font-weight-bold" data-market-id="FR40" data-sort-column="sentiment-short" data-stream-type="sentiment" data-type="short-value-info" data-value="--">

问题是而是数字值' - ' 'data_value'。

我的目标是根据“ data-market-id”（'gbpusd'，'fr40'）找到“数据值”。

任何潜在客户都将不胜感激。

I am new to web scraping.

I am trying to download the Net Long position from https://www.dailyfx.com/sentiment site. The value is situated in div with class 'dfx-technicalSentimentCard__netLongContainer' and span attribute 'data-value'.

My code is:

import requests
from bs4 import BeautifulSoup as bs

url = 'https://www.dailyfx.com/sentiment'

all_pages_reviews = []
response = requests.get(url)
soup = bs(response.content, 'html.parser')

rev_div = soup.findAll("span",attrs={"class","dfx-rateDetail__percentageInfoText font-weight-bold"})

print(rev_div)

This gives rev_div as "bs4.element.ResultSet" with following output:

</span>, <span class="dfx-rateDetail__percentageInfoText font-weight-bold" data-market-id="GBPUSD" data-sort-column="sentiment-long" data-stream-type="sentiment" data-type="long-value-info" data-value="--">

</span>, <span class="dfx-rateDetail__percentageInfoText font-weight-bold" data-market-id="FR40" data-sort-column="sentiment-short" data-stream-type="sentiment" data-type="short-value-info" data-value="--">
