Selenium无法定位并填充保险报价表单中投保人名字输入框的问题求助

我现在正在尝试自动化完成一个保险报价表单的填写流程——需要从存储的PDF文件里提取各类信息，然后填入网页表单中。第一个要填充的是**投保人名字（Applicant First Name）**输入框，但Selenium一直报错，说找不到这个文本框。我现在有点摸不着头脑，能不能帮我看看我哪里做错了，以及正确的实现方式应该是怎样的？

目标输入框的元素代码 #

<input name="ctl00$ConPlaceHolder$FirstName" type="text" id="ctl00_ConPlaceHolder_FirstName" maxlength="30" class="fdata" onmouseover="showContents(this,10)" onblur="makeUpperCase(this);" onchange="enableCreditButton()" onfocus="this.select()" style="width: 100%; visibility: visible; background-color: rgb(255, 222, 161);" size="15" title="">

元素的定位路径 #

• XPath：//*[@id="ctl00_ConPlaceHolder_FirstName"]
• Full XPath：/html/body/form/div[6]/div/div[5]/div/table[1]/tbody/tr[5]/td[1]/font/input

    quote_data.append(quote_entry)

quote_data = pd.DataFrame(quote_data)

# 遍历数据填入表单
for index, row in quote_data.iterrows():
    # 等待元素加载
    time.sleep(5)
    
    # 以下是我尝试过但都失败的定位方式（针对投保人名字输入框）

    # WebDriverWait(driver, 20).until( EC.presence_of_element_located((By.NAME, "ctl00$ConPlaceHolder$FirstName")) ).send_keys(row["First Name"])
    
    # 2.
    # WebDriverWait(driver, 20).until( EC.presence_of_element_located((By.ID, "ctl00_ConPlaceHolder_FirstName")) ).send_keys(row["First Name"])
    
    # 3.
    # first_name_field = WebDriverWait(driver, 20).until( EC.presence_of_element_located((By.XPATH, "//input[@id='ctl00_ConPlaceHolder_FirstName']")) ) first_name_field.send_keys(row["First Name"])
    
    # 4.
    # first_name_field = WebDriverWait(driver, 30).until( EC.presence_of_element_located((By.XPATH, "/html/body/form/div[6]/div/div[5]/div/table[1]/tbody/tr[5]/td[1]/font/input")) ) first_name_field.send_keys(row["First Name"])
    
    # 其他输入框填写逻辑
    
    # 提交报价请求
    driver.find_element(By.NAME, "submitQuote").click()

我单独尝试过的定位填充代码 #

我原本以为下面这些方法至少有一个能成功填充输入框，但全部都失败了：

1. 使用name属性定位：

WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.NAME, "ctl00$ConPlaceHolder$FirstName"))).send_keys(row["First Name"])

2. 使用ID属性定位：

WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.ID, "ctl00_ConPlaceHolder_FirstName"))).send_keys(row["First Name"])

3. 基于ID的XPath定位：

first_name_field = WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, "//input[@id='ctl00_ConPlaceHolder_FirstName']"))) 
first_name_field.send_keys(row["First Name"])

4. 使用Full XPath定位：

first_name_field = WebDriverWait(driver, 30).until(EC.presence_of_element_located((By.XPATH, "/html/body/form/div[6]/div/div[5]/div/table[1]/tbody/tr[5]/td[1]/font/input"))) 
first_name_field.send_keys(row["First Name"])

我是Selenium的新手，如果有什么明显的遗漏还请大家见谅，非常感谢大家能提供帮助！
