给定的HTML代码如下：
<a id="hlExcel" href="Reports\DC_REG_638123088090882623.xls" target="_blank">
<img src="Images/Excel.gif" alt="Click to view a Excel version">
</a>
要点击这个可点击的元素，尽管文件名每天都会更改，理想情况下，您需要使用WebDriverWait来等待元素变为可点击状态，您可以使用以下任何一种定位策略：
- 使用CSS选择器：
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#hlExcel > img[alt='Click to view a Excel version']"))).click()
- 使用XPath：
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@id='hlExcel']/img[@alt='Click to view a Excel version']"))).click()
- 注意: 您需要添加以下导入语句：
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
请根据您的需求选择其中一种定位策略来点击元素。

Given the HTML:
<a id="hlExcel" href="Reports\DC_REG_638123088090882623.xls" target="_blank">
<img src="Images/Excel.gif" alt="Click to view a Excel version">
</a>
To click on the clickable element even though the file name changes every day ideally you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:
-
Using CSS_SELECTOR:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#hlExcel > img[alt='Click to view a Excel version']"))).click() -
Using XPATH:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@id='hlExcel']/img[@alt='Click to view a Excel version']"))).click() -
Note: You have to add the following imports :
from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC

你可以尝试进行部分匹配。DC_REG是否出现在所有文件名中？如果你知道一个无论名称变化多少次都会出现在名称中的模式，你可以寻找该模式。类似于
link = browser.find_element_by_css_selector('a[href*="REG"][href$=".xls"]')
link.click()
英文:
You could go for a partial match maybe. Is the DC_REG common in all file names ? If you know a pattern which will be part of the name irrespective of how many times the name changes, you could look for that pattern. Something like
link = browser.find_element_by_css_selector('a[href*="REG"][href$=".xls"]')
link.click()
