我正在使用webdriver.Chrome(硒),通过以下网址获取存储在svg交互式地图下的链接:https : //www.mpcb.gov.in/water-quality
我曾尝试使用像xpath,partial_text等不同的find_elements_by_功能,但没有成功。这是我的代码的开始:
DRIVER_PATH = 'C:/Users/Asaf/Desktop/Asaf/Python/chromedriver.exe'
options = Options()
options.headless = True
options.add_argument("--window-size=1920,1200")
driver = webdriver.Chrome(executable_path=DRIVER_PATH)
# Site URL
url='https://www.mpcb.gov.in/water-quality'
driver.get(url)
为了说明这一点,我想获取这些链接(地图的可单击区域),以便一次从它们中抓取数据。
要从svg交互式地图获取链接,请在新标签页中打开链接以从其中抓取数据,一次可以使用以下“定位器策略”:
代码块:
driver.get('https://www.mpcb.gov.in/water-quality')
hrefs = [my_elem.get_attribute("xlink:href") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div[property='schema:text'] svg g a")))]
parent_window = driver.current_window_handle
for href in hrefs:
driver.execute_script("window.open('" + href +"')")
WebDriverWait(driver, 10).until(EC.number_of_windows_to_be(2))
windows_after = driver.window_handles
new_window = [x for x in windows_after if x != parent_window][0]
driver.switch_to_window(new_window)
print(driver.current_url)
driver.close()
driver.switch_to_window(parent_window)
driver.quit()
控制台输出:
