有人能帮我吗，谢谢。根据您的最新评论，第二个窗口（至少）似乎不会包含
“/*[@id='create\u button']]”或中的至少一个。
“/*[@id='update\u button']”。在此情况下，在下面的代码块中
if driver.find_element_by_xpath(xpath2):
driver.find_element_by_xpath(xpath2).click()
driver.close()
elif driver.find_element_by_xpath(xpath3):
driver.find_element_by_xpath(xpath3).click()
driver.close()
至少有一个
if driver.find_element_by_xpath(xpath2):
或
将抛出一个ElementNotFoundException
将您发送到except
块
这是因为执行driver.find\u element\u by\u xpath（）
会在元素未定位时抛出此类错误
我不确定你想完成什么，或者你的页面看起来是什么样子，所以我不知道要做什么修复，但这似乎是你问题的原因。如果你能提供更多的细节，确切地说，你正试图做这个循环，我可能能够建议一个修复
再想一想，以下方法可能有效：
在某处添加此导入和功能：
from selenium.common.exceptions import NoSuchElementException
def check_exists_by_xpath(xpath):
try:
webdriver.find_element_by_xpath(xpath)
except NoSuchElementException:
return False
return True
然后，将原始if块更改为：
if check_exists_by_xpath(xpath2):
driver.find_element_by_xpath(xpath2).click()
driver.close()
elif check_exists_by_xpath(xpath3):
driver.find_element_by_xpath(xpath3).click()
driver.close()
编辑这和我想的差不多。有帮助吗

看起来您当前的问题很简单，您正试图将带有字母字符的字符串转换为需要严格数字值的浮点。excel工作表上的任何数据都无法转换为数字。您能上传所收到错误的全文吗？我有点困惑到底是什么问题。另外，由于xPath有问题，您可以上传HTML或URL链接吗？最后，在哪里定义了driver
？例如，如果您正在使用Chrome，则需要以这种方式定义驱动程序：driver=webdriver.Chrome（executable_path=“/path/to/binary/chromedriver”）在第二次检查中，我不知道您想做什么。您首先在哪里打开浏览器？Selenium函数，如通过xPath查找内容，需要打开web浏览器，因为这是Selenium唯一可以与之交互的东西。在路径顶部有一些代码，我无论如何都不能共享。我认为，如果没有完整的HTML或页面URL，就不可能调试xPath。最后，你能粘贴你得到的错误的全文吗？没有得到任何错误。进程以退出代码0结束。我不知道在哪里定义check_exists_by_xpath（xpath）函数。所以也发布我的前半段代码。从selenium导入webdriver从selenium.common.exceptions导入NoSuchElementException导入xlrd driver=webdriver.Chrome（r'C:\Users\tmou\PycharmProjects\Python\WebScraping\chromedriver.exe）driver.maximize_window（）driver.get（'））driver.get（'））driver.switch_to.frame（'ST_mainFrame'））emailElem=driver.通过xpath（'/*[@id=“log\u main”]/input'）emailElem.send\u key（'xshdfg@xyz.com“）passwordElem=driver.find_element_by_xpath（'/*[@id=“log\u main”]/p[1]/input'）passwordElem.send_key（'/*.####passwd=passwordElem.find_element_by_xpath（'/*[@id=“log\u main”]/p[2]/input'）。单击（）驱动程序。切换到父框架（）驱动程序。切换到.frame（'topFrame'）驱动程序。通过css选择器（'.menu>ul:nth child（1）>li:nth child（7）>a:nth child（1）>span:nth child（1）'）查找元素。单击（）报告驱动程序。切换到.parent\u frame（）驱动程序。切换到.frame（'stu mainFrame'）驱动程序。通过css选择器（'div.menu行：nth child（16）>span:nth child（3）>标签：nth child（2）查找元素.click（）#FTO driver.切换到.frame（'FTO_details'）驱动程序。通过css选择器（'html body table tbody tr td form table tbody tr td a img'）查找元素。单击（）#如果通过xpath（xpath2）
在检查是否存在的右上方定义元素，则搜索应该有效。您将希望import语句与其他语句一起位于文件的顶部。你能在你的问题中加上那个代码吗？在这样的注释中阅读是非常困难的。Excel包含如下值：1615525 1652273 4C17461624 1649059 Xapth:xpath=“//输入[@value='Analyze'和contains（@onclick，“+st_string+”）”将只接受字符串，因此我尝试将它们转换为字符串。如果您只想将它们转换为字符串，为什么不简单地使用st_string=str（st）？我想您可以这样做，但第53行也有“st==float（st）”，我相信这会导致您当前的错误。是的，因为Excel值是整数和字符串，当我们在代码中使用Excel时，整数将被视为浮点数，所以我尝试将它们转换为INT，然后转换为STR。我直接转换为字符串，但是.0将在结尾处，我不希望出现。#C.Peck让你现在检查一下。
