Question

我正在尝试使用BeautifulSoup从此HTML中提取一些数据。我只想返回data-buyout="1 alchemy" data-ign="DanForeverr" data-league="Standard" data-name="Sulphur Wastes Map" data-seller="NoCocent" data-sellerid="None" data-tab="~price 1 alch" data-x="6" data-y="7" *`，但我没有得到任何结果。我正在使用下面的代码。任何帮助将不胜感激。

parsed = soup.find_all('tbody', class=re.compile('^data-'))

<tbody class="item item-live-c324ceb98e25716a0fad0727e0cd64e3" data-buyout="1 alchemy" data-ign="DanForeverr" data-league="Standard" data-name="Sulphur Wastes Map" data-seller="NoCocent" data-sellerid="None" data-tab="~price 1 alch" data-x="6" data-y="7" id="item-container-0">

Answer 1

嗯，你真的不能那样做，你可以从那个标签中提取特定信息，如。

定义x = html您发布的内容如下：x = '''<tbody class="item item-live-c324ceb98e25716a0fad0727e0cd64e3" data-buyout="1 alchemy" data-ign="DanForeverr" data-league="Standard" data-name="Sulphur Wastes Map" data-seller="NoCocent" data-sellerid="None" data-tab="~price 1 alch" data-x="6" data-y="7" id="item-container-0">'''

soup = BeautifulSoup(x,'lxml')

this_class = soup.findAll('tbody',{'class':'item item-live-c324ceb98e25716a0fad0727e0cd64e3'})
#This is used to pinpoint the exact tbody (you can do it your way),
# but it's useful because you give it the exacty key-value. (Mostly can't miss)

for i in this_class:
    print(i['data-buyout'])
    print(i['data-ign'])
    print(i['data-name'])
    print(i['id'])

您可以打印这些属性的每个值，但如果您使用 soup.findAll或sou.find，则 NOT 仅打印（< em>一个）分支，还有整个树 （儿童）

Answer 2

您正在尝试在标记类中查找标记属性，但这不起作用。

为什么不通过ID找到它？只需确保它包含0之前的子字符串。

soup.select("tbody[id*=item-container-]")

Answer 3

以下的组合解决了我的问题

parsed = soup.select("tbody[id*=item-container-]")
for i in parsed:
    print(i['data-buyout'])
    print(i['data-ign'])
    print(i['data-name'])
    print(i['id'])

使用BeautifulSoup从tbody中提取数据
