蟒蛇BeautifulSoup得到select.value不是文本

Question

<select> 
    <option value="0">2002/12</option> 
    <option value="1">2003/12</option> 
    <option value="2">2004/12</option> 
    <option value="3">2005/12</option> 
    <option value="4">2006/12</option> 
    <option value="5" selected>2007/12</option> 
</select> 

與此代碼，我需要價值'0'作爲'2002/12'

我嘗試了很多的BS4選擇，.stripped_strings，.strip()，.contents，get()等

不是文字

如何獲取值不是文本？

Answer 1

你想要value屬性;使用訪問tag attributes映射語法：

option['value'] 

演示：

>>> from bs4 import BeautifulSoup 
>>> soup = BeautifulSoup('''\ 
... <select> 
... <option value="0">2002/12</option> 
... <option value="1">2003/12</option> 
... <option value="2">2004/12</option> 
... <option value="3">2005/12</option> 
... <option value="4">2006/12</option> 
... <option value="5" selected>2007/12</option> 
... </select> 
... ''') 
>>> for option in soup.find_all('option'): 
...  print 'value: {}, text: {}'.format(option['value'], option.text) 
... 
value: 0, text: 2002/12 
value: 1, text: 2003/12 
value: 2, text: 2004/12 
value: 3, text: 2005/12 
value: 4, text: 2006/12 
value: 5, text: 2007/12

像這樣：

>>> import BeautifulSoup 
>>> doc = """ 
... <select> 
... <option value="0">2002/12</option> 
... <option value="1">2003/12</option> 
... <option value="2">2004/12</option> 
... <option value="3">2005/12</option> 
... <option value="4">2006/12</option> 
... <option value="5" selected>2007/12</option> 
... </select> 
... """ 
>>> soup = BeautifulSoup.BeautifulSoup(doc) 
>>> list = soup.findAll('option') 
>>> for l in list: 
... print l['value'] 
... 
0 
1 
2 
3 
4 
5 
>>>
