python - 在 Beautifulsoup 中提取值(value)

Question

我有以下代码:

f = open(path, 'r')
html = f.read() # no parameters => reads to eof and returns string

soup = BeautifulSoup(html)
schoolname = soup.findAll(attrs={'id':'ctl00_ContentPlaceHolder1_SchoolProfileUserControl_SchoolHeaderLabel'})
print schoolname

给出:

[<span id="ctl00_ContentPlaceHolder1_SchoolProfileUserControl_SchoolHeaderLabel">A B Paterson College, Arundel, QLD</span>]

当我尝试使用 schoolname['value'] 访问该值(即“A B Paterson College, Arundel, QLD”)时，出现以下错误:

print schoolname['value'] TypeError: list indices must be integers, not str

为了获得这个值我做错了什么？

Answer 1

您可以使用contents沿着树向下移动:

>>> for x in schoolname:
>>>    print x.contents
[u'A B Paterson College, Arundel, QLD']    

请注意，内容不一定是字符串 - 一般来说，它也可以是更多标签或字符串和标签的混合。
