how to find not the next sibling but the 2nd sibling or find sibling "a" OR sinbling "b"

[localpricemaps]

i have some html which looks like this where i want to scrape out the
href stuff (the www.cnn.com part)

<div class="noFood"> Cheese</div>
<div class="food">Bl ue</div>
<a class="btn" href = "http://www.cnn.com">
so i wrote this code which scrapes it perfectly:

for incident in row('div', {'class':'noFoo d'}):
b = incident.findNe xtSibling('div' , {'class': 'food'})
print b
n = b.findNextSibli ng('a', {'class': 'btn'})
print n
link = n['href'] + "','"

problem is that sometimes the 2nd tag , the <div class="food"> tag , is
sometimes called food, sometimes called drink. so sometimes it looks
like this:

<div class="noFood"> Cheese</div>
<div class="drink">P epsi</div>
<a class="btn" href = "http://www.cnn.com">

how do i alter my script to take into account the fact that i will
sometimes have food and sometimes have drink as the class name? is
there a way to say "look for food or drink" or a way to say "look for
this incident and then find not the next sibling but the 2nd next
sibling" if that makes any sense?

thanks

well actually all i want it to do is find the first thing that shows up
whether its class:food or class: drink so that works for me. only
thing is that after it finds class:food i think it runs through the
html again and finds the following class:drink and being that there is
not class tag after that class: drink tag it fails.

ok i found something that works. instead of using the def i did this:

for incident in row('div', {'class': 'food' or 'drink' }):

and it worked!

'food' or 'drink' doesn't do what you think it does:

>>> 'food' or 'drink' 'food'
>>> {'class': 'food' or 'drink'}

{'class': 'food'}

what makes you think that looking "food" only will find either "food"
or "drink" ?
