Selenium 无法按类名查找元素

Question

<table class="sc-fAEnHe ePMtc">
<tbody>
<tr class="sc-fAEnHe ePMtc">
<td classs"sc-jEECVv IBUtl">
</td>
</tr>

当我使用 Selenium 的按类查找元素时，它能够找到该元素，我什至尝试用“.”、“-”和“_”替换空格(在 e 和 r 或 v 和 I 之后)但是它没有用。 我使用了下面的代码

try:
    match_history_table = WebDriverWait(driver, 30).until(
        EC.presence_of_element_located((By.CLASS_NAME, 'sc-fAEnHe ePMtc'))
    )
except Exception:
    print("Error Finding Match History Table")
    driver.quit()

它总是返回异常(EC 是 selenium.webdriver.support.expected_conditions) >注意:按标签查找元素对我来说不是一个选项

这是来自 By.CLASS_NAME 的文档，在 selenium-java-bindings 中找到。

Find elements based on the value of the "class" attribute. Only one class name should be used. If an element has multiple classes, please use cssSelector(String).

尝试使用 (By.CSS_SELECTOR, '.sc-fAEnHe.ePMtc'):

try:
    match_history_table = WebDriverWait(driver, 30).until(
        EC.presence_of_element_located((By.CSS_SELECTOR, '.sc-fAEnHe.ePMtc'))
    )
except Exception:
    print("Error Finding Match History Table")
    driver.quit()
