python - 从抓取的数据中分割 html (Python+BeautifulSoup4)

Question

我遇到了一个问题，即在没有获取所有 html 数据的情况下抓取标签内的文本。这是我的 python 代码。我想要抓取的文本不在跨度类内，并且在标签中独立存在。这是文本放置位置的示例。

<a href="/counterstrike/rankings/team-details/32537">
  <span class="ranking">49</span>
  <span class="flag flag-pl" data-tooltip="" tabindex="1" title="Poland></span>
  TEXT-I-WANT-TO-SCRAPE
  <span class="elo">1103</span>
</a>

如果我使用“.text.encode('utf8').lstrip().rstrip()”函数，我仍然得到这样的数据:

print(textt) '49\n \n\n\n TEXT-I-WANT-TO-SCRAPE \n \n 1103'

我的问题是如何只获取标签内的文本？

抓取 elo 和排名没有问题，因为它们包含在具有特定类的跨度内。

def get_matches():
matches = get_parsed_page("https://www.gosugamers.net/counterstrike/rankings")
rankings = matches.find("ul", {"class": "ranking-list"})
matchdays = rankings.find_all("li")

for match in matchdays:
    matchDetails = match.find_all("a")

    for getMatch in matchDetails:
        elo = match.find("span", {"class": "elo"}).text.encode('utf8').lstrip().rstrip()
        ranking = match.find("span", {"class": "ranking"}).text.encode('utf8').lstrip().rstrip()
        textt = match.find("a").text.encode('utf8').lstrip().rstrip()

        print(ranking,elo,textt)

致以诚挚的问候

Answer 1

使用next_element获取标签的下一个元素的文本。尝试下面的代码。使用正则表达式查找特定的href来抓取 .

from bs4 import BeautifulSoup
import requests
import re
data=requests.get("https://www.gosugamers.net/counterstrike/rankings").text
soup=BeautifulSoup(data,'html.parser')
for a in soup.find_all('a',href=re.compile("/counterstrike/rankings/team-details")):
    ranking=a.find('span' , class_='ranking').text.replace('\n','').strip()
    name=a.find('span', class_='ranking').next_element.next_element.next_element.next_element.replace('\n','').strip()
    elo=a.find('span',class_='elo').text.replace('\n','').strip()
    print(ranking,name,elo)
