所以我試圖獲取該網(wǎng)站的左側(cè)欄： https:?//experience.arcgis.com/experience/685d0ace521648f8a5beeeee1b9125cd以獲取當(dāng)前的世界衛(wèi)生組織冠狀病毒數(shù)據(jù)。我通過(guò) Xpath 定位國(guó)家/地區(qū)，我的代碼是：from selenium import webdriverimport timedriver = webdriver.Firefox()driver.get("link_to_the_page")time.sleep(30)countries = country = "/html/body/div/div/div[2]/div/div/div/margin-container/full-container/div[10]/margin-container/full-container/div/div[2]/nav/span/div/div/p/span"countries_name = driver.find_elements_by_xpath(countries)但是當(dāng)我運(yùn)行這個(gè)時(shí)，列表是空的，這很奇怪，因?yàn)楫?dāng) Firefox 使用 Selenium 顯示頁(yè)面時(shí)，頁(yè)面看起來(lái)完全相同。那么為什么瀏覽器找不到元素呢？

或者，您可以直接在此處獲取數(shù)據(jù)：
https://services.arcgis.com/5T5nSi527N4F7luB/arcgis/rest/services/Historic_adm0_v3/FeatureServer/0/query?f=json&where=1%3D1&returnGeometry=false&spatialRel=esriSpatialRelIntersects&outFields=ADM0_NAME%2Ccum_conf%2CDateOfDataEntry&orderByFields=DateOfDataEntry%20asc&resultOffset=2000&resultRecordCount=2000&cacheHint=true
解析json，然后做你想做的事。

由于所需的元素位于一個(gè)內(nèi)部，<iframe>因此要訪(fǎng)問(wèn)所需的元素，您必須：
誘導(dǎo)WebDriverWait等待所需的frame_to_be_available_and_switch_to_it().
誘導(dǎo)WebDriverWait等待所需的visibility_of_all_elements_located().
您可以使用以下定位策略：
driver.get("https://experience.arcgis.com/experience/685d0ace521648f8a5beeeee1b9125cd")
WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.TAG_NAME,"iframe")))
print([my_elem.text for my_elem in WebDriverWait(driver,20).until(EC.visibility_of_all_elements_located((By.XPATH, "//strong[contains(., 'areas or territories with cases')]//following::div[1]//div[@class='external-html']//span")))])

先進(jìn)入iframedriver.switch_to.frame(driver.find_element_by_css_selector("/html/body/div[2]/div[1]/div/div/div/div/div/div/div/iframe"))
country = driver.find_element_by_xpath("//*[@id="Cases_by_country_pt_V3_6708_0_layer"]/circle[32]")
country .click()
不要復(fù)制“完整xpath”，應(yīng)該復(fù)制“xpath”
