what have tried far.
#!/usr/bin/env python # encoding: utf-8 __future__ import unicode_literals contextlib import closing selenium.webdriver import firefox selenium.webdriver.support.ui import webdriverwait import beautifulsoup import time url = "http://www..." def texttospeech(): closing(firefox()) browser: try: browser.get(url) except selenium.common.exceptions.timeoutexception: print "timeout" browser.find_element_by_id("ttstext").send_keys("hello.") button = browser.find_element_by_id("commitbtn") button.click() time.sleep(10) webdriverwait(browser, timeout=100).until( lambda x: x.find_element_by_id('audioplayer')) src = browser.page_source return src def getaudio(source): soup = beautifulsoup.beautifulsoup(source) audio = soup.find("div", {"id": "audioplayer"}) return audio.string if __name__ == "__main__": print getaudio(texttospeech()) the key success url resulting mp3 file. don't know how wait script change html (inner text of <div id="audioplayer">). code returns none, because takes result sooner.
in case of changes, not enough wait element:
webdriverwait(browser, timeout=100).until( lambda x: x.find_element_by_id('audioplayer')) but need wait change condition, using expectedcondition. started (not tested):
from selenium.webdriver.support import expected_conditions ec wait_text = 'file=http://' element = webdriverwait(driver, 10).until( ec.text_to_be_present_in_element((by.id, "mydynamicelement"), wait_text) ) you can checkout expected conditions here: http://selenium-python.readthedocs.org/en/latest/api.html?highlight=text_to_be_present_in_element#module-selenium.webdriver.support.expected_conditions
