On the link that contains 'alpha' in the URL has many links(hrefs) which I would like to collect from 20 different pages and paste onto the end of the general url(second last line). The href are found in a table which class is mys-elastic mys-left for the td and the a is obviously the element which contains the href attribute. Any help would greatly be appreciated for I have been working at this for about a week.
for i in range(1, 11):
# The HTML Scraper for the 20 pages that list all the exhibitors
url = 'http://ahr13.mapyourshow.com/5_0/exhibitor_results.cfm?alpha=%40&type=alpha&page=' + str(i) + '#GotoResults'
print url
list_html = scraperwiki.scrape(url)
root = lxml.html.fromstring(list_html)
href_element = root.cssselect('td.mys-elastic mys-left a')
for element in href_element:
# Convert HTMl to lxml Object
href = href_element.get('href')
print href
page_html = scraperwiki.scrape('http://ahr13.mapyourshow.com' + href)
print page_html
No need to muck about with javascript - it's all there in the html:
import scraperwiki
import lxml.html
html = scraperwiki.scrape('http://ahr13.mapyourshow.com/5_0/exhibitor_results.cfm? alpha=%40&type=alpha&page=1')
root = lxml.html.fromstring(html)
# get the links
hrefs = root.xpath('//td[@class="mys-elastic mys-left"]/a')
for href in hrefs:
print 'http://ahr13.mapyourshow.com' + href.attrib['href']
import lxml.html as lh
from itertools import chain
URL = 'http://ahr13.mapyourshow.com/5_0/exhibitor_results.cfm?alpha=%40&type=alpha&page='
BASE = 'http://ahr13.mapyourshow.com'
path = '//table[2]//td[@class="mys-elastic mys-left"]//@href'
results = []
for i in range(1,21):
doc=lh.parse(URL+str(i))
results.append(BASE+i for i in doc.xpath(path))
print list(chain(*results))
