Python - Looping through HTML Tags and using IF

I am using python to extract data from a webpage. The webpage has a reoccurring html div tag with class = "result" which contains other data in it (such as location, organisation etc...). I am able to successfully loop through the html using beautiful soup but when I add a condition such as if a certain word ('NHS' for e.g.) exists in the segment it doesn't return anything - though I know certain segments contain it. This is the code:

soup = BeautifulSoup(content)
details = soup.findAll('div', {'class': 'result'})

for detail in details:
    if 'NHS' in detail:
        print detail

Hope my question makes sense...
