python - 怎么从BeautifulSoup得到的ResultSet里搜索想要的部分？

Question

python脚本里的语句是

from bs4 import BeautifulSoup
import urllib2

response = urllib2.urlopen('http://xxxxxx')
html = response.read()
soup = BeautifulSoup(html)

res = soup.find_all(class_='pro-detail-price')

得到的res是ResultSet类型，print结果是：

[<p class="pro-detail-price">最低价格：￥<span>4399.0</span>(天猫旗舰店)
<p class="pro-detail-trend">
<iframe frameborder="0" height="210" scrolling="no" src="http://tool.manmanbuy.com/historyPro.aspx?w=290&amp;amp;h=210&amp;m=1&amp;e=0&amp;scroll=0&amp;id=327958" width="290"></iframe>
</p>
</p>]

如果想在这个ResultSet里找到特定的标签改用什么办法呢？ 比如找到<span>4399.0</span>里的4399.0

Answer 1

res = soup.find(class_='pro-detail-price').find('span').string

Is this okay?

Answer 2

I remember that find will only return the first matching result, and findAll will return ResultSet
So the find result should be directly res.span.string, if not, just res[0].span .stringbar

Answer 3

find_all() and find() are not easy to use. The best one for bs is select(), which is the CSS selector.
You have obtained a large frame, for example, it is a Tag in soup, then: find_all()和find()都不好用，bs最好用的是select()，即CSS选择器。
你已经获取了一个大框架吧，比如它是soup中的一个Tag，然后：

results = tag.select('p[class="pro-detail-price"] span')

你这个例子里，results[0] rrreee

In your example, results[0] is the specified tag. 🎜

Answer 4

from bs4 import BeautifulSoup
import urllib2

response = urllib2.urlopen('http://xxxxxx')
html = response.read()
soup = BeautifulSoup(html)

res = soup(class_='pro-detail-price')

for sp in res:
    print sp.span.string

I tried it randomly, and the output result of changing to this code is 4399.0, but I hope the master can provide a better way, thank you

Answer 5

In the results found by find, you can use the CSS selector select to perform the next positioning search.

Answer 6

soup.find("p", class_='pro-detail-price').find("span").text
