c# html html-agility-pack parsing windows-phone-8

题

我实际上是在试图解析这个网页的内容， http：//www.cryptocoincharts.info/v2/coins/show/tips

特别是我需要得到数字，如“当前难度”，“到现在为止开采的硬币”等

我实际上不确定如何做到这一点，我实际上找到了我的数字所在的部分，但我无法编写代码来实际获取这些数字:(

在此处输入图像描述

在此先感谢您的帮助！

编辑：这是我到目前为止的代码：

protected async override void OnNavigatedTo(NavigationEventArgs e)
        {
            base.OnNavigatedTo(e);
            string htmlPage = "";
            using (var client = new HttpClient())
            {
                try
                {
                    htmlPage = await client.GetStringAsync("http://www.cryptocoincharts.info/v2/coins/show/tips");
                }
                catch (HttpRequestException exc) { }
            }

        HtmlDocument htmlDocument = new HtmlDocument();
        htmlDocument.LoadHtml(htmlPage);

HttpClient client = new HttpClient();
var doc = new HtmlAgilityPack.HtmlDocument();
var html = await client.GetStringAsync("http://www.cryptocoincharts.info/v2/coins/show/tips");
doc.LoadHtml(html);

var result = doc.DocumentNode.SelectSingleNode("//table[@class='table table-striped']")
                .Descendants("tr")
                .Skip(1)
                .Select(tr => new
                {
                    Desc = tr.SelectSingleNode("td[1]").InnerText,
                    Val = WebUtility.HtmlDecode(tr.SelectSingleNode("td[2]").InnerText)
                })
                .ToList();
