Selenium 打印出与预期不同的文本

Question

我想从剑桥词典中获取美式发音目前我的代码在这里：

from selenium import webdriver
from YDSData import tdata, dummydata

words = dummydata
link='https://dictionary.cambridge.org/dictionary/english'

driver = webdriver.Chrome()

for word in words:
    driver.get(link+"/"+str(i))
    try:
        result = driver.find_elements_by_xpath('//*[@id="page-content"]/div[2]/div[1]/div[2]/div/div[3]/div/div/div[1]/div[2]/span[2]/span[3]/span')
        print(content)
    except:
      driver.close()

此代码本应为我提供剑桥词典中的美国发音，但它打印出：

[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="6f609e22-76ab-443d-8216-4ac90aefda20")>]
[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="c7d8a664-d162-4d2c-8c87-dd8e10211024")>]
[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="7f163600-d25f-4000-893f-44693736ed41")>]

另外，它非常慢是代码有问题吗？

编辑：

我重写了答案部分的代码以解决问题，现在代码如下所示：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from YDSData import tdata, dummydata

driver = webdriver.Chrome()

driver.get("https://dictionary.cambridge.org/dictionary/english/dictionary")

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[text()='us']//following-sibling::span[@class='pron dpron']"))).get_attribute("innerHTML"))

它可以工作，但代码需要 8 分钟才能工作并出现以下错误：

Answer 1

这些是：

[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="6f609e22-76ab-443d-8216-4ac90aefda20")>]
[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="c7d8a664-d162-4d2c-8c87-dd8e10211024")>]
[<selenium.webdriver.remote.webelement.WebElement (session="285ac250c8925dd19eb01a7853c1f219", element="7f163600-d25f-4000-893f-44693736ed41")>]

当您在控制台上打印它们时。

要打印文本 /ˈdɪk.ʃən.er.i/，您可以使用以下：

使用 xpath:

driver.get("https://dictionary.cambridge.org/dictionary/english/dictionary")
print(driver.find_element(By.XPATH, "//span[text()='us']//following-sibling::span[@class='pron dpron']").text)

要提取文本 /dɪk.ʃən.er.i/ 理想情况下，您需要归纳 WebDriverWait for the and you can use the following ：

使用 XPATH:

driver.get("https://dictionary.cambridge.org/dictionary/english/dictionary")
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[text()='us']//following-sibling::span[@class='pron dpron']"))).get_attribute("innerHTML"))

控制台输出：
```
/ˈdɪk.ʃən.er.i/
```

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
