搜索一组否定词

Question

这是我今天早上提出的问题的后续 - Using Beatiful Soup to get data from non-class section

我正在尝试获取一组信息并针对一组关键字进行搜索。如果在信息集中找到关键字，我想保释。但是，即使关键字在信息集中，我的代码也没有找到关键字

negative_keywords = ['basement', 'unfinished', 'hardwood']  #defined at beginning of script


bodyContents = soup.find(attrs={'id' : 'postingbody'})
for validate in negative_keywords:
    if (string.find(str(bodyContents.string).lower(),validate) != -1):
        keyword_found = TRUE
        continue

这是样本数据

<section id="postingbody">


        3BR/2BA newly renovated ranch

<p>
    <b></b>

Answer 1

我会这样做

import BeautifulSoup

negative_keywords = ['basement', 'unfinished', 'hardwood']

html = '''
<section id="postingbody">
    Looking for a corporate rental, this beautiful decorated 5 BR,
    4.5 BA two story house is in a desirable location, 7 minutes off
    I 85. Beautiful solid cherry cabinets in kitchen and laundry room.
    All stainless steel appliances. Hardwood floors in kitchen and foyer,
    Ceramic tile floors in all bathrooms, laundry room, dining room and sunroom.

    <br>
    </br>

</section>
'''

soup = BeautifulSoup.BeautifulSoup(html)
bodyContents = soup.find(attrs={'id' : 'postingbody'})

if any([k in bodyContents.getText().lower() for k in negative_keywords]):
    print "keyword was found"
