Xpath无法正确执行

Question

我有以下Xpath

"//*[@id="idDownloadDataMenuo:portalgo~r:report"]/table/tbody/tr[1]/td[1]/a[1]/table/tbody/tr/td[1]/img"

和以下CSS

"#idDownloadDataMenuo\3a portalgo\7e r\3a report > table > tbody > tr:nth-child(1) > td.shadowMenuCell > a:nth-child(1)" 

当我尝试单击该路径后，发现抛出以下错误。

也尝试了很多组合 “消息：没有这样的元素：无法找到元素：{” method“：” xpath“，” selector“：” // * [@ id ='idDownloadDataMenuo：portalgo〜r：report'] // td [ text（）='CSV格式']“}”

相同的Xpath在控制台中也起作用，下面是输出。

''' $x("//*[@id='idDownloadDataMenuo:portalgo~r:report']//td[text()='CSV Format']")
 '''

下面是我的代码

browser.execute_script('''window.open("https://XXXXXXXXX.XXXXXXXX=YYYYYYYYYYYY%20report","_blank");''')
time.sleep(40)

#findpath = "//td[text()='CSV Format'] or //td[contains(text(),'report')]"
findpath = "//*[@id='idDownloadDataMenuo:portalgo~r:report']//td[text()='CSV Format']"

browser.find_element_by_xpath(findpath).click()

我的完整HTML标记对于CSV部件，类似地，PDF，EXCEL也具有相同的类。
