[英]How to select tags by attribute value with Beautiful Soup
I have the following HTML fragment:我有以下 HTML 片段:
>>> a
<div class="headercolumn">
<h2>
<a class="results" data-name="result-name" href="/xxy> my text</a>
</h2>
I am trying to select header column only if attribute data-name="result-name"仅当属性 data-name="result-name" 时,我才尝试选择标题列
I've tried:我试过了:
>>> a.select('a["data-name="result-name""]')
This gives:这给出:
ValueError: Unsupported or invalid CSS selector:
How can I get this working?我怎样才能让它工作?
You can simply do this :你可以简单地这样做:
soup = BeautifulSoup(html)
results = soup.findAll("a", {"data-name" : "result-name"})
Source : How to find tags with only certain attributes - BeautifulSoup来源: 如何查找仅具有某些属性的标签 - BeautifulSoup
html = """
<div class="headercolumn">
<h2>
<a class="results" data-name="result-name" href="/xxy> my text</a>
</h2>
"""
from bs4 import BeautifulSoup
soup = BeautifulSoup(html)
for d in soup.findAll("div",{"class":"headercolumn"}):
print d.a.get("data-name")
print d.select("a.results")
result-name
[<a class="results" data-name="result-name" href="/xxy> my text</a></h2>"></a>]
select classes or ids选择类或 ID
soup.select('a.gamers') # select an `a` tag with the class gamers
soup.select('a#gamer') # select an `a` tag with the id gamer
select single attr:选择单个属性:
soup.select('a[attr="value"]')
select multiple attr:选择多个属性:
attr_dict = {
'attr1': 'val1',
'attr2': 'val2',
'attr3': 'val3'
}
soup.findAll('a', attr_dict)
you can use any CSS selector in soup.select
你可以在soup.select
使用任何CSS选择器
