Can not get all <li> tags from list in specific Div tag

[deepak....@mindgearstechnologies.com]

i am trying geting urls from li tag but getting only one li instead of all,  i tried all beautifulsoup and lxml, html parser.

i want all images from li in div class="viewport" in url given below

my code is as bellow...

from lxml import html

hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',

       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',

       'Accept-Encoding': 'none',

       'Accept-Language': 'en-US,en;q=0.8',

       'Connection': 'keep-alive'}

url ="http://www.thomson.co.uk/destinations/africa/cape-verde/cape-verde-islands/santa-maria-cape-verde-isl/hotels/tui-sensimar-cabo-verde.html"

doc = html.parse(url)

rows = doc.xpath('//div[@class="viewport"]//ul/li/img')

for row in rows:

       print(row.attrib['src'], row.text_content())

i also tried using Beutifulsoup method as below

req = urllib2.Request(url, headers=hdr)

        

content = urllib2.urlopen(req)

soup = BeautifulSoup(content, "lxml")

ul = soup.find("ul", class_='plist')

li = ul.find_all('li')

        

for l in li:

     img = l.img['src']

but getting onlyy one image src instead of all.
