Преобразование HTML-таблицы с rowspans в datatable C#
I need to convert a Html Table to DataTable in C#. I used HtmlAgilityPack but it does not convert it well because of rowspans. The code I am currently using is:
private static DataTable convertHtmlTableToDataTable()
{
WebClient webClient = new WebClient();
string urlContent = webClient.DownloadString("http://example.com");
string tableCode = getTableCode(urlContent);
string htmlCode = tableCode.Replace(" ", " ");
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(htmlCode);
var headers = doc.DocumentNode.SelectNodes("//tr/th");
DataTable table = new DataTable();
foreach (HtmlNode header in headers)
{
table.Columns.Add(header.InnerText);
}
foreach (var row in doc.DocumentNode.SelectNodes("//tr[td]"))
{
table.Rows.Add(row.SelectNodes("td").Select(td => td.InnerText).ToArray());
}
return table;
}
And this is a part of Html Table:
<pre lang="HTML"> <table class="tabel" cellspacing="0" border="0">
<caption style="font-family:Verdana; font-size:20px;">SEMGRP</caption>
<tr>
<th class="celula" >Ora</th>
<th class="latime_celula celula">Luni</th>
<th class="latime_celula celula">Marti</th>
<th class="latime_celula celula">Miercuri</th>
