我有一个使用以下 XPath 的自动化 Selenium 测试

"//tr[td/strong='Riparian 2m Ungrazed - RBS' and td/button[@id='btnDeleteOption_WG']]"

目前，每当我查询此 XPath 时，它都会返回我需要的元素，但也会返回另一个不在屏幕上的隐藏元素。

我已经比较了这两个元素，唯一的区别如下

offsetHeight: 39           offsetHeight: 0
offsetLeft: 8              offsetLeft: 0
offsetParent: td           offsetParent: null
offsetTop: 10              offsetTop: 0
offsetWidth: 179           offsetWidth: 0

我需要在左侧找到 offsetParent 的元素<td>。

任何人都可以通过 XPath 帮助找到这个吗？

谢谢！

下面是该元素的 HTML：

<td class="text-center" style="white-space: nowrap;">
  <button id="btnShowItems_WG" class="btn btn-sm btn-primary" ng-disabled="!WG_field.optionHasItems" ng-click="WG_field.optionHasItems ? items.visible = !items.visible : false;" title="View Items" disabled="disabled">
        <span class="glyphicon glyphicon-list"></span>
    </button>
  <button ng-hide="!efsEditRole_RoleAssignedToUser" ng-disabled="false" id="btnAddOptionItem_16_WG" class="btn btn-primary btn-sm" ng-click="appSummaryVm.addItem($index, 'WG'); appSummaryVm.addItemsByOption(WG_field.fieldId, WG_field.tranche, WG_field.optionCode, WG_field.optionTypeId, $index, 'WG');"
    title="Add Item" aria-hidden="false">
        <span class="glyphicon glyphicon-plus"></span>
    </button>

您可以获得所有元素并按可见性过滤它们。下面是一个 Java 代码示例，如何从 Web 元素列表中获取第一个可见元素。

使用 Java 8：

List<WebElement> elements = driver.findElements(By.xpath("//tr[td/strong='Riparian 2m Ungrazed - RBS' and td/button[@id='btnDeleteOption_WG']]"));
WebElement element = elements
        .stream()
        .filter(WebElement::isDisplayed)
        .collect(Collectors.toList())
        .get(0);

Python：

elements = driver.find_elements_by_xpath("//tr[td/strong='Riparian 2m Ungrazed - RBS' and td/button[@id='btnDeleteOption_WG']]")
visible_one = list(filter(lambda x: x.is_displayed(), elements))[0]
visible_one.click()
