Power Automate - 云流 - 使用 xpath 作为父节点属性

Question

1. RESTful API 调用返回下面注明的 XML。

2. 我需要为每个 ShowSurveyAnswerKey 循环执行各个步骤。所以在这种情况下，有 8 个。使用以下“应用到每个”步骤表达式即可：

xpath(xml(body('HTTP_Get')),'//ShowSurveyAnswer')

3. 在“Apply to every”中，需要知道 ShowSurveyKey、ShowSurveyQuestionKey 和 ShowSurveyAnswerKey 的值。我唯一可以工作的是 ShowSurveyAnswerKey，我碰巧正在使用“撰写”动作进行测试，其表达式为：

xpath(item(),'string(/ShowSurveyAnswer/@ShowSurveyAnswerKey)')

所以真的，我无法在“应用到每个”中的 Power Automate Compose Expression 中找出父级或祖先或 ../。

非常感谢所有帮助。谢谢！
