# coding: utf-8 selenium import webdriver selenium.webdriver.common.by import  browser = webdriver.firefox() browser.get('http://s.cafef.vn/lich-su-giao-dich-hsg-1.chn')  next_page_link = browser.find_element_by_partial_link_text('>') next_page_link.click() next_page_link = browser.find_element_by_partial_link_text('>') next_page_link.click() next_page_link = browser.find_element_by_partial_link_text('>') next_page_link.click()

here exception

traceback (most recent call last):   file "cafef.py", line 13, in <module>     next_page_link.click()   file "/usr/local/lib/python2.7/dist-packages/selenium-2.40.0-py2.7.egg/selenium/webdriver/remote/webelement.py", line 59, in click     self._execute(command.click_element)   file "/usr/local/lib/python2.7/dist-packages/selenium-2.40.0-py2.7.egg/selenium/webdriver/remote/webelement.py", line 369, in _execute     return self._parent.execute(command, params)   file "/usr/local/lib/python2.7/dist-packages/selenium-2.40.0-py2.7.egg/selenium/webdriver/remote/webdriver.py", line 164, in execute     self.error_handler.check_response(response)   file "/usr/local/lib/python2.7/dist-packages/selenium-2.40.0-py2.7.egg/selenium/webdriver/remote/errorhandler.py", line 164, in check_response     raise exception_class(message, screen, stacktrace) selenium.common.exceptions.staleelementreferenceexception: message: u'element no longer attached dom' ; stacktrace:      @ fxdriver.cache.getelementat (resource://fxdriver/modules/web_element_cache.js:7613)     @ utils.getelementat (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:7210)     @ fxdriver.preconditions.visible (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:8223)     @ delayedcommand.prototype.checkpreconditions_ (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:10861)     @ delayedcommand.prototype.executeinternal_/h (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:10878)     @ delayedcommand.prototype.executeinternal_ (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:10883)     @ delayedcommand.prototype.execute/< (file:///tmp/tmpidosdw/extensions/fxdriver@googlecode.com/components/command_processor.js:10825)

the second next_page_link.click() call occurring before browser has loaded next page. add wait.until ec.element_to_be_clickable:

from selenium import webdriver import selenium.webdriver.support.ui ui selenium.webdriver.common.by import import selenium.webdriver.support.expected_conditions ec  import contextlib  contextlib.closing(webdriver.firefox()) browser:     browser.get('http://s.cafef.vn/lich-su-giao-dich-hsg-1.chn')     wait = ui.webdriverwait(browser, 10)     in range(3):                     next_page_link = wait.until(             ec.element_to_be_clickable((by.partial_link_text, '>')))         next_page_link.click()
