You can use a css selector, pulling the span you want using the title text :
您可以使用 css 选择器，使用标题文本拉出您想要的跨度：
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)
That finds the spanwith a titleattribute that contains RAM, it is equivalent to saying in python, if "RAM" in span["title"].
那就是找到一个包含RAM的title属性的span，相当于在 python 中说，.if "RAM" in span["title"]
Or using findwith re.compile
或者使用find和re.compile
import re
print(soup.find("span", title=re.compile("RAM")).text)
To get all the data:
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)
Which will give you:
这会给你：
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
000 Plus Recommended Operating System Requirement Win Xp 32
000 Plus Recommended Hard Disk Drive Space Requirement 500 MB

You can simply use spantag in BeautifulSoup or you can include other attributes like class, titlealong with the spantag.
您可以简单地span在 BeautifulSoup 中使用标签，也可以包含其他属性，例如class,title以及span标签。
from BeautifulSoup import BeautifulSoup as BSHTML
htmlText = """<div class="systemRequirementsMainBox">
<div class="systemRequirementsRamContent">
<span title="000 Plus Minimum RAM Requirement">1 GB</span> </div>"""
soup = BSHTML(htmlText)
spans = soup.findAll('span')
# spans = soup.findAll('span', attrs = {'class' : 'your-class-name'}) # or span by class name
# spans = soup.findAll('span', attrs = {'title' : '000 Plus Minimum RAM Requirement'}) # or span with a title
for span in spans:
print span.text
