I am trying to extract the content of a single “value” attribute in a specific “input” tag on a webpage. I use the following code:
import urllib f = urllib.urlopen("http://58.68.130.147") s = f.read() f.close() from BeautifulSoup import BeautifulStoneSoup soup = BeautifulStoneSoup(s) inputTag = soup.findAll(attrs={"name" : "stainfo"}) output = inputTag['value'] print str(output)
I get TypeError: list indices must be integers, not str
Even though, from the Beautifulsoup documentation, I understand that strings should not be a problem here… but I am no specialist, and I may have misunderstood.
Any suggestion is greatly appreciated!

Answer
.find_all()
returns list of all found elements, so:
input_tag = soup.find_all(attrs={"name" : "stainfo"})
input_tag
is a list (probably containing only one element). Depending on what you want exactly you either should do:
output = input_tag[0]['value']
or use .find()
method which returns only one (first) found element:
input_tag = soup.find(attrs={"name": "stainfo"}) output = input_tag['value']
