HtmlAgilityPack SelectNode 不适用于 WP8.1

Question

在我的控制台项目中，它运行良好...但是当我在 windows phone 8.1 上运行时，它不起作用。有什么问题？

HtmlNodeCollection NoAltElements = HD.DocumentNode.SelectNodes("//div[@class='f2p-card']//div[@class='champion-info']//a[@href]");


HtmlNodeCollection NoAltElements = HD.DocumentNode.SelectNodes("//div[@class='white-stone']//a[@href]");

"im trying to make .SelectsNodes() on WP8.1, but cant understand how can i do this if XPath doesnt support on WP8.1"

当 HtmlAgilityPack (HAP) XPath API 不可用时，常见的替代方法是 LINQ API，例如：

IEnumerable<HtmlNode> NoAltElements =
                        HD.DocumentNode
                          .Descendants("div")
                          .Where(o => o.GetAttributeValue("class", "") == "f2p-card")
                          .SelectMany(o => o.Descendants("div"))
                          .Where(o => o.GetAttributeValue("class", "") == "champion-info")
                          .SelectMany(o => o.Descendants("a"))
                          .Where(o => o.GetAttributeValue("href", null) != null);

IEnumerable<HtmlNode> NoAltElements = 
                        HD.DocumentNode
                          .Descendants("div")
                          .Where(o => o .GetAttributeValue("class","") == "white-stone")
                          .SelectMany(o => o.Descendants("a"))
                          .Where(o => o .GetAttributeValue("href",null) != null);
