Selenium 选择表中的第一行，即使我正在遍历行

Question

我真的不确定这里发生了什么，也想不通，所以希望有人可以帮助我。

本质上，我正在选择一个表，然后查找该表中的所有行。从这里开始，我循环浏览行并选中三个复选框并检查它们是否被选中。但是，我为每一行获得的结果始终是第一行的结果。例如

假 真 假

然后。。。

假 真 假

何时应更改每一行。

Python/Selenium code：

table = driver.find_element_by_xpath("//table[@id='tableMscRatesModal']/tbody")
rows = table.find_elements(By.XPATH, "//tr[@class='ng-scope']") # get all of the rows in the tables
for row in rows:
print(row.text)
manager_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='1']")
standard_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='2']")
no_box = row.find_element_by_xpath("//td/input[@type='radio'][contains(@name, 'userRole')][@value='3']")
print(manager_box.is_selected())
print(standard_box.is_selected())
print(no_box.is_selected())
if not (manager_box.is_selected() or standard_box.is_selected() or no_box.is_selected()):
standard_box.send_keys(Keys.SPACE)

我在下面列出了两行的示例。对于 x 行数，重复此操作完全相同。

.HTML：

<table id="tableMscRatesModal" ng-table="tableParams" class="table table-striped table-bordered" show-filter="false">
<colgroup>

提前感谢！

当使用xpath从另一个元素中查找元素时，您需要使用当前上下文.

for row in rows:
manager_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='1']")
standard_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='2']")
no_box = row.find_element_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')][@value='3']")

如果使用列表，还可以简化代码

checkboxes = row.find_elements_by_xpath(".//td/input[@type='radio'][contains(@name, 'userRole')]")
for checkbox in checkboxes:
print(checkboxes.is_selected())

如果你放下print(row)，甚至更远

checkboxes = row.find_elements_by_xpath("//table[@id='tableMscRatesModal']/tbody//tr[@class='ng-scope']//td/input[@type='radio']")
for i in range(0, len(checkboxes), 3):
print(checkboxes[i].is_selected())
print(checkboxes[i + 1].is_selected())
print(checkboxes[i + 2].is_selected())
