C# 查询使用HTML Agility Pack解析的网页时出现问题

C# 查询使用HTML Agility Pack解析的网页时出现问题,c#,web-scraping,html-agility-pack,C#,Web Scraping,Html Agility Pack,我有以下源代码snipet: <div class = "discount_tools_row"> <div class = "discount_tools"> <ul> <li><a href = "#" class = "share-discount" rel = "nofollow"></a></li> <li><a href = "/deal/map

我有以下源代码snipet:

<div class = "discount_tools_row">
  <div class = "discount_tools">
    <ul> 
      <li><a href = "#" class = "share-discount" rel = "nofollow"></a></li>
      <li><a href = "/deal/map/4243683"
             class = "show-location"
             title = "הראה מקום על מפה"
             data-address = "רח&#39; האצ&quot;ל 39, ראשון לציון"></a></li>
    </ul>

    <link rel = "prerender"
          href = "http:/ / www.bigdeal.co.il / ? CampaignId = 873 & sId = 10 ">
    <a class = "tavo_button"
       data-provider = "bigdeal"
       href = "http : //www.bigdeal.co.il/?CampaignId=873&sId=10"
       target="_blank"
       rel = "nofollow">תבוא!</a>
    </div>
  </div>
</div>
我试图实现所有目标

< div class = "discount_tools" >
属性在其子节点和

  <a class="tavo_button" data-provider="bigdeal" href=
这是我的解决方案:

        var nodes = doc.DocumentNode.SelectNodes("//div[@class=\"discount_tools\"]");
        var linksCollections = nodes.Select(node => node.Descendants("a"));

        List<string> Locations = new List<string>();
        List<string> Categories = new List<string>();
        List<string> Hrefs = new List<string>();

        foreach (var col in linksCollections)
        {
            string location, category, href;
            location = GetAtt("data-address",col);
            if (!string.IsNullOrEmpty(location))
            {
                category = GetAtt("data-kind", col);
                if (!string.IsNullOrEmpty(category))
                {
                    href = GetAtt("data-provider", "href", col);
                    if (!string.IsNullOrEmpty(href))
                    {
                        Locations.Add(location);
                        Categories.Add(category);
                        Hrefs.Add(href);
                    }
                }
            }

        }
var nodes=doc.DocumentNode.SelectNodes(“//div[@class=\“折扣工具\”]”);
var linksCollections=nodes.Select(node=>node.substands(“a”);
列表位置=新列表();
列表类别=新列表();
List Hrefs=新列表();
foreach(链接集合中的变量列)
{
字符串位置、类别、href;
位置=GetAtt(“数据地址”,col);
如果(!string.IsNullOrEmpty(位置))
{
类别=GetAtt(“数据类型”,col);
如果(!string.IsNullOrEmpty(类别))
{
href=GetAtt(“数据提供者”,“href”,col);
如果(!string.IsNullOrEmpty(href))
{
位置。添加(位置);
类别。添加(类别);
添加(href);
}
}
}
}
  <a class="tavo_button" data-provider="bigdeal" href=
        var nodes = doc.DocumentNode.SelectNodes("//div[@class=\"discount_tools\"]");
        var linksCollections = nodes.Select(node => node.Descendants("a"));

        List<string> Locations = new List<string>();
        List<string> Categories = new List<string>();
        List<string> Hrefs = new List<string>();

        foreach (var col in linksCollections)
        {
            string location, category, href;
            location = GetAtt("data-address",col);
            if (!string.IsNullOrEmpty(location))
            {
                category = GetAtt("data-kind", col);
                if (!string.IsNullOrEmpty(category))
                {

                    }
                }
            }

        }
String dataAddressValue = doc.DocumentNode.SelectSingleNode("//div[@class='discount_tools']/ul/li/a[@class='show-location']").Attributes["data-address"].Value;

String LinkHrefValue = doc.DocumentNode.SelectSingleNode("//div[@class='discount_tools ']/link[@rel=’prerender’]").Attributes["href"].Value;
