如何从BeautifulSoup中的span标签获取文本 [英] How to get text from span tag in BeautifulSoup

问题描述

我的链接看起来像这样

<div class="systemRequirementsMainBox">
<div class="systemRequirementsRamContent">
<span title="000 Plus Minimum RAM Requirement">1 GB</span> </div>

我正在尝试从那里获取1 GB.我尝试过

I'm trying to get 1 GB from there. I tried

tt  = [a['title'] for a in soup.select(".systemRequirementsRamContent span")]
for ram in tt:
    if "RAM" in ram.split():
        print (soup.string)

它输出None.

我尝试了a['text']，但它给了我KeyError.我该如何解决?我的错误是什么?

I tried a['text'] but it gives me KeyError. How can I fix this and what is my mistake?

推荐答案

您可以使用css选择器，使用标题文本拉出所需的跨度:

You can use a css selector, pulling the span you want using the title text :

soup = BeautifulSoup("""<div class="systemRequirementsMainBox">
<div class="systemRequirementsRamContent">
<span title="000 Plus Minimum RAM Requirement">1 GB</span> </div>""", "xml")

print(soup.select_one("span[title*=RAM]").text)

找到具有 title 属性且包含 RAM 的 span ，这等效于在python中说if "RAM" in span["title"].

That finds the span with a title attribute that contains RAM, it is equivalent to saying in python, if "RAM" in span["title"].

或在 re.compile

import re
print(soup.find("span", title=re.compile("RAM")).text)

要获取所有数据:

from bs4 import BeautifulSoup 
r  = requests.get("http://www.game-debate.com/games/index.php?g_id=21580&game=000%20Plus").content

soup = BeautifulSoup(r,"lxml")
cont = soup.select_one("div.systemRequirementsRamContent")
ram = cont.select_one("span")
print(ram["title"], ram.text)
for span in soup.select("div.systemRequirementsSmallerBox.sysReqGameSmallBox span"):
        print(span["title"],span.text)

哪个会给你:

000 Plus Minimum RAM Requirement 1 GB
000 Plus Minimum Operating System Requirement Win Xp 32
000 Plus Minimum Direct X Requirement DX 9
000 Plus Minimum Hard Disk Drive Space Requirement 500 MB
000 Plus GD Adjusted Operating System Requirement Win Xp 32
000 Plus GD Adjusted Direct X Requirement DX 9
000 Plus GD Adjusted Hard Disk Drive Space Requirement 500 MB
