Question

我想用Html Agility Pack抓取数据。我用过这个：

string url = @"https://mobile.bet365.gr/#type=Coupon;key=1-1-13-40-141-0-0-0-1-0-0-4100-0-0-1-0-0-0-0-0-0;ip=0;lng=5;anim=1";
var webGet = new HtmlWeb();
var document = webGet.Load(url);
var nodes = document.DocumentNode.SelectNodes("//*[@id='Coupon']/div[1]/div[2]/div[1]/div/div[1]/div[1]/span");

int i = 0;

foreach (var node in nodes)
{
    dataGridView1.Rows.Add();
    dataGridView1.Rows[i].Cells[0].Value = i + 1;
    dataGridView1.Rows[i].Cells[1].Value = node.InnerHtml;
    i++;
}

XPath取自FireXPath，但没有出现。

HTML代码段是：

有人能帮我找到正确的XPath吗？我在其他网站上使用了这种技术，并且我已经获得了我想要的结果，但是从这个网站我找到正确的XPath有一些问题。

Answer 1

您可以从HTML代码段中获取您的团队和赔率：

HtmlDocument document = new HtmlDocument();
document.Load(Server.MapPath("xpath.html"));

// Teams
HtmlNodeCollection teamNodes = document.DocumentNode.SelectNodes("//div[@class='ippg-Market_CompetitorName']");

List<string> teams = new List<string>();

foreach (HtmlNode n in teamNodes)
{
    HtmlNode nodeTeam = n.SelectSingleNode(".//span[@class='ippg-Market_Truncator']");

    if (nodeTeam != null)
    {
        teams.Add(nodeTeam.InnerText);
    }
}

// Odds
HtmlNodeCollection oddNodes = document.DocumentNode.SelectNodes("//span[@class='ippg-Market_Odds']");

List<string> odds = new List<string>();

foreach (HtmlNode o in oddNodes)
{
    odds.Add(o.InnerText);
}

FireXPath的XPath不适用于Html Agility Pack
