它同桌重複

<table border="1" cellpadding="3" bordercolordark="#993300" bordercolorlight="#FF6600"> 

與它<tbody>。那<tbody>有幾個<tr>標籤。首先<tr>是一個頭/標題和第二<tr>標籤內容/值

我想這些錶轉換成數據表

我怎樣寫一個XPath的代碼，這樣我可以分裂4個HTML表格（其中有實際內容）？

到目前爲止，我試過，但我得到的錯誤與此代碼

HtmlDocument myHtml = new HtmlDocument(); 
myHtml.LoadHtml(stringHTML); 

ParseAllTables(myHtml); 

private static DataTable[] ParseAllTables(HtmlDocument doc) 
{ 
    var result = new List<DataTable>(); 
    foreach (var table in doc.DocumentNode.Descendants("table")) 
    { 
     result.Add(ParseTable(table)); 
    } 
    return result.ToArray(); 
} 

private static DataTable ParseTable(HtmlNode table) 
{ 
    var result = new DataTable(); 

    var rows = table.Descendants("tr"); 

    var header = rows.Take(1).First(); 
    foreach (var column in header.Descendants("td")) 
    { 
     result.Columns.Add(new DataColumn(column.InnerText, typeof(string))); 
    } 

    foreach (var row in rows.Skip(1)) 
    { 
     var data = new List<string>(); 
     foreach (var column in row.Descendants("td")) 
     { 
      data.Add(column.InnerText); 
     } 
     result.Rows.Add(data.ToArray()); 
    } 
    return result; 
} 

我只在乎<TR>標籤是表裏面<table border="1" cellpadding="3" bordercolordark="#993300" bordercolorlight="#FF6600">

首先<TR>的數據表頭 從二<TR>是數據表數據

Answer 1

這工作，

//table[@cellpadding='0' and @cellspacing='0']/tr[1]
