Python 从Beauty soup中的图表中提取文本

对beautifulsoup来说比较新，我正试图从这个网页中提取数据：

我想抓住标题“程序完成者”、“雇佣的第二季度”下的数字。html代码的相关部分是：

<ul class="listbox">              
 <li class="li1">
  <p style="cursor:help" class="listtop" title="WIA Adult 
  completers are those individuals who have exited a WIA Adult program from 
  which the individual received a core staff-assisted service (such as job 
  search or placement assistance) or an intensive service (such as
  counseling, career planning, or job training). Those individuals who 
  participated in WIA through self-service, like OhioMeansJobs.com, or other 
  less intensive programs are not included in the dashboard.">Program 
  Completers</p>
  <p id="programcompleters1">18</p></li>

这将返回文本，但网页的其他部分也标记为“ul”。我未能从图表区域内获取任何文本。如何检索所需的文本

谢谢你的帮助

所需的元素位于iframe中。尝试在以下位置从页面本身提取

所以，这应该行得通

url="http://reports.workforce.test.ohio.gov/WIAReports/WIA_COUNTY.ASPX?level=county&DataType=hIp9ibmBIwbKor1WvT5Bkg==&name=GTL8gAmmdulY5GSlycy7WQ==&programDate=Kf/2jvCFFRgQJjODWV7l08ATxxM/adw9p1FWfZ9J7O8="
page = urllib2.urlopen(url)
soup = BeautifulSoup(page)

chartcontainers = soup.findAll('div', {"class": "chartcontain"})
for container in chartcontainers:
    print(container)
    #then do whatever

如前所述，您要查找的数据位于iframe中，请按照@selected_codex的说明访问它：

然后，您可以通过以下方式访问感兴趣的字段：

data = {}
for tag in soup.find_all('p'):
    if tag.get('id'):
        data[tag.get('id')] = tag.text

print(data)

>> print(data.get('programcompleters1'))
18

非常感谢。两个答案都有效，但是@Matt_Davidson的解决方案让我得到了我正在寻找的更具体的数据。

data = {}
for tag in soup.find_all('p'):
    if tag.get('id'):
        data[tag.get('id')] = tag.text

print(data)

>> print(data.get('programcompleters1'))
18
