Question

我正在使用一个非常简单的方法来获取所需的信息：

a = soup.find_all(class_ = "pull-right hidden-phone")
print(a)
print(a[0])

输出为：

[<span class="pull-right hidden-phone"><span data-c="190000000" data-time="1535345254000">1.9 BTC</span></span>, <span class="pull-right hidden-phone"><span data-c="4890548" data-time="1535345254000">0.04890548 BTC</span></span>]
<span class="pull-right hidden-phone"><span data-c="190000000" data-time="1535345254000">1.9 BTC</span></span>

我想获得1.9 BTC或190000000，但不知道如何获得。我已经尝试过print(a[0]["data-time"])，但它不起作用，它说

返回self.attrs [key] KeyError：“数据时间”

但是，此print(a[0]["class"])可以工作并给出['pull-right', 'hidden-phone']。

那么我如何获得1.9 BTC或190000000？

Answer 1

使用print(a.find("span").span["data-time"])或print(a.span.span["data-time"])

例如：

from bs4 import BeautifulSoup
s = """<span class="pull-right hidden-phone"><span data-c="190000000" data-time="1535345254000">1.9 BTC</span></span>"""
a = BeautifulSoup(s, "html.parser")

print(a.find("span").span["data-time"])
print(a.span.span["data-c"])
print(a.span.span.text)

输出：

1535345254000
190000000
1.9 BTC

Answer 2

您应该尝试这种方式，希望有帮助

from bs4 import BeautifulSoup
text = """
<span class="pull-right hidden-phone"><span data-c="190000000" data-time="1535345254000">1.9 BTC</span></span>, 
<span class="pull-right hidden-phone"><span data-c="4890548" data-time="1535345254000">0.04890548 BTC</span></span>
"""

soup = BeautifulSoup(text, 'html.parser')
for tag in soup.find_all('span', attrs={'class': 'pull-right hidden-phone'}):
    span_tag = tag.span
    print('Attribute Value:', span_tag.get('data-c'), 'Date-time:', span_tag.get('data-time'), 'Tag Text:', span_tag.get_text())


# Output as: 
# Attribute Value: 190000000 Date-time: 1535345254000 Tag Text: 1.9 BTC
# Attribute Value: 4890548 Date-time: 1535345254000 Tag Text: 0.04890548 BTC

BeautifulSoup获得一定价值
