目标网页: http://www.immi.gov.au/skilled/general-skilled-migration/estimated-allocation-times.htm
我要提取的部分:
<tr>
<td>Skilled – Independent (Residence) subclass 885<br />online</td>
<td>N/A</td>
<td>N/A</td>
<td>N/A</td>
<td>15 May 2011</td>
<td>N/A</td>
</tr>
代码通过搜索关键字“子类885在线”找到此部分后,应该打印第5个标记内的日期“ 5月15日2011年“如上所示。
这只是我自己的监视器,可以密切关注移民申请的进展情况。

我认为这正是他的想法!
模拟海龟可能会做这样的事情:
>>> from BeautifulSoup import BeautifulSoup
>>> import urllib2
>>> url = 'http://www.immi.gov.au/skilled/general-skilled-migration/estimated-allocation-times.htm'
>>> page = urllib2.urlopen(url)
>>> soup = BeautifulSoup(page)
>>> for row in soup.html.body.findAll('tr'):
... data = row.findAll('td')
... if data and 'subclass 885online' in data[0].text:
... print data[4].text
...
15 May 2011
但是我不确定它会有所帮助,因为那个日期已经过去了!
祝你好运!
