请有人可以在 xpath 中提供不同的帮助吗？我正在尝试进行一些查询，以返回一年之后出生的不同 Actor 的数量，并且在一部电影或一部电视节目中的奖励金额超过了奖励金额。
所以首先我选择他们出生年份高于年份参数的所有 Actor ，然后我使用计数来计算他们的奖项。但现在我有重复的名字，我怎样才能区分我的结果？
我的代码:
public int Query6(XmlDocument xmlDoc, String yearOfBirth, int amountOfAwards)
{
string s = "//actors/actor[year-of-birth>'" + yearOfBirth + "'][count(awards/award)>"+amountOfAwards+"]";
XmlNodeList xmlNodeList = xmlDoc.SelectNodes(s);
return xmlNodeList.Count;
}

例如，如果我选择 1980 年和 3 个奖项，那么在我的结果中“Daniel Radcliffe”将计算两次，我只希望他获得 1 个。
我正在用 C# 编写。
请您参考如下方法:
这在 XPath 1.0 中不容易做到，但在 XPath 2.0 中很容易。与 .NET 捆绑在一起的 Microsoft XPath 引擎不支持 XPath 2.0，但有来自第三方(例如 Saxon)的替代方案支持。
我不确定您到底想要什么输出，但如果您执行一个选择一组 actor 的查询元素(假设结果在 $selectedActors 中)，那么您可以使用distinct-values($selectedActors/concat(first-name, ' ', last-name))
XPath 自 1.0 以来已经走过了漫长的道路。不幸的是，微软从未实现过更高版本:他们更希望您转向他们自己的专有技术 (LINQ)。您是迁移到 LINQ 还是迁移到来自第三方的更高版本的 XPath 引擎取决于您对 Microsoft 锁定的态度。
