我想根据名称打印属性值,例如
<META NAME="City" content="Austin">
我想做这样的事情
soup = BeautifulSoup(f) //f is some HTML containing the above meta tag
for meta_tag in soup('meta'):
if meta_tag['name'] == 'City':
print meta_tag['content']
上面的代码给出KeyError: 'name'
,我相信这是因为BeatifulSoup使用了name,所以它不能用作关键字参数。

这很简单,请使用以下内容 -
>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('<META NAME="City" content="Austin">')
>>> soup.find("meta", {"name":"City"})
<meta name="City" content="Austin" />
>>> soup.find("meta", {"name":"City"})['content']
u'Austin'
如果有任何不明确的地方,请发表评论。

theharshest 回答了这个问题,但这是另一种做同样事情的方法。 此外,在您的示例中,您有大写的NAME,在您的代码中,您有小写的名称。
s = '<div class="question" id="get attrs" name="python" x="something">Hello World</div>'
soup = BeautifulSoup(s)
attributes_dictionary = soup.find('div').attrs
print attributes_dictionary
# prints: {'id': 'get attrs', 'x': 'something', 'class': ['question'], 'name': 'python'}
print attributes_dictionary['class'][0]
# prints: question
print soup.find('div').get_text()
# prints: Hello World

以下作品:
from bs4 import BeautifulSoup
soup = BeautifulSoup('<META NAME="City" content="Austin">', 'html.parser')
metas = soup.find_all("meta")
for meta in metas:
print meta.attrs['content'], meta.attrs['name']

晚会结束6年但我一直在寻找如何提取 html元素的标签 属性值,因此适用于:
<span property="addressLocality">Ayr</span>
我想要“addressLocality”。我一直被引导到这里,但答案并没有真正解决我的问题。
我最终是如何做到的:
>>> from bs4 import BeautifulSoup as bs
>>> soup = bs('<span property="addressLocality">Ayr</span>', 'html.parser')
>>> my_attributes = soup.find().attrs
>>> my_attributes
{u'property': u'addressLocality'}
因为它是一个词典,你也可以使用keys
和'值'
>>> my_attributes.keys()
[u'property']
>>> my_attributes.values()
[u'addressLocality']
希望它可以帮助别人!

也可以试试这个解决方案:
查找以表格
的范围写入的值<强> htmlContent 强>
<table>
<tr>
<th>
ID
</th>
<th>
Name
</th>
</tr>
<tr>
<td>
<span name="spanId" class="spanclass">ID123</span>
</td>
<td>
<span>Bonny</span>
</td>
</tr>
</table>
Python代码
soup = BeautifulSoup(htmlContent, "lxml")
soup.prettify()
tables = soup.find_all("table")
for table in tables:
storeValueRows = table.find_all("tr")
thValue = storeValueRows[0].find_all("th")[0].string
if (thValue == "ID"): # with this condition I am verifying that this html is correct, that I wanted.
value = storeValueRows[1].find_all("span")[0].string
value = value.strip()
# storeValueRows[1] will represent <tr> tag of table located at first index and find_all("span")[0] will give me <span> tag and '.string' will give me value
# value.strip() - will remove space from start and end of the string.
# find using attribute :
value = storeValueRows[1].find("span", {"name":"spanId"})['class']
print value
# this will print spanclass
