无法在 python 中找到文本的 xpath 元素

Question

我通过调用python方法编写机器人进行自动化测试。在 python 中，我使用 xpath 在 python 中查找文本“Branch TH1”。 这是参考，

str_name = 'Branch TH1'
text_element = self.driver.find_element(*AdminAccountsLocators.FILTROS_TABLE)
FILTROS_TABLE = (By.ID, 'ctl00_ContentPlaceHolder_tcUser_tpFilter_cblScopeFilters')

这是我的脚本，

path = ("//*[contains(text(),'%s')]/../input/.." %str_name)
WebDriverWait(self.driver, 20).until(EC.element_to_be_clickable((path)))
selected_element = text_element.find_element_by_xpath(path)

这是我要测试的网页代码，

<div id="ctl00_ContentPlaceHolder_tcUser_tpFilter" class="ajax__tab_panel" style="visibility: visible;">
            
                                                        <div id="ctl00_ContentPlaceHolder_tcUser_tpFilter_upEditViewFilters">

This is when I find the xpath manually 你会看到我可以手动找到元素 "//*[contains(text(),'Branch TH1')]/../input/.." 作为红色框突出显示的 1of1，但它没有突出显示代码行（不确定这是否是重点）。

在我运行它之后，它抛出了一个错误： TypeError: find_element() 接受 1 到 3 个位置参数，但给出了 38 个

我不确定在运行机器人时是否有任何东西阻塞了我想要找到的 xpath。请帮忙。

Answer 1

你的 XPath 表达式：

//*[contains(text(),'%s')]/../input/..

会找到一个td 元素。如果要单击包含特定文本的复选框，则应定位 input 元素。感兴趣的 XPath 可能是：

//input[following-sibling::label[.="Branch TH1"]]

所以你可以使用类似的东西：

name = 'Branch TH1'
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[following-sibling::label[.='%s']]"% str(name)))).click()

进口：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

编辑：如果您需要查找特定文本来验证元素的存在，请使用：

name = 'Branch TH1'
print(WebDriverWait(driver, 20).until(EC.presence_of_element_located((By.XPATH, "//*[contains(text(),'%s')]"% str(name)))))
