[localpricemaps@gmail.com]

i have this html:

<td class="price">

<a class="nojs" name="D1L4" href="/xPopups/nojs"
target="_blank" >3.99</a>


<div class="food">1. 05</div>


<div class="drink">3 </div>

<a class="btn" name="D1" href="http://www.cnn.com"
target="_blank" onclick="reload ()">

i tried to this use this python to scrape out the href cnn.com and
failed.

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

and i tried this
for incident in row('td', {'class':'price '}):
n = incident.findNe xtSibling('a', {'class': 'btn'})
info = n['href'] + "','"
print info
