Getting the nth element using BeautifulSoup

Question

From a large table I want to read rows 5, 10, 15, 20 ... using BeautifulSoup. How do I do this? Is findNextSibling and an incrementing counter the way to go?

Another option, if you prefer raw html...

"""Build a small table with one column and ten rows, then parse it into a list"""
htstring = """
 
 
foo1
 
 
 
foo2
 
 
 
foo3
 
 
 
foo4
 
 
 
foo5
 
  
 
foo6
 
  
 
foo7
 
  
 
foo8
 
  
 
foo9
 
  
 
foo10
 
"""
result = [html_tr for idx, html_tr in enumerate(soup.findAll('tr')) \
     if (idx+1)%5==0]
print result

Running that...

[mpenning@Bucksnort ~]$ python testme.py
[ foo5 ,  foo10 ]
[mpenning@Bucksnort ~]$
