使用HTML Agility Pack刪除表列

asp.net c# html-agility-pack html-table

我已經使用C#從我自己的網站上刪除了一個表格並將其加載到一個字符串中。有太多列,所以我想知道是否有一種簡單的方法可以刪除一些,可能使用HTML Agility Pack,但如果需要,可以使用C#。

字符串中的表格如下所示:

    <table>
        <tr>
            <th scope="col">&nbsp; </th>
            <th scope="col">&nbsp; </th>
            <th scope="col">P </th>
            <th scope="col">W </th>
            <th scope="col">L </th>
            <th scope="col">T </th>
            <th scope="col">NR </th>
            <th scope="col">Bat </th>
            <th scope="col">Bowl </th>
            <th scope="col">Pen </th>
            <th scope="col">Pts </th>
        </tr>
        <tr>

我想刪除8-10列(蝙蝠,碗和筆)。我不確定從哪裡開始所以任何指針都會有所幫助!

一般承認的答案

您需要遍歷每個tr並從每個節點中刪除第8,第9和第10個td節點。

bool first = true;
foreach (HtmlNode row in doc.DocumentNode.SelectNodes("//tr"))
{
    if (first)
    {
        row.RemoveChild(row.SelectSingleNode("th[10]"));
        row.RemoveChild(row.SelectSingleNode("th[9]"));
        row.RemoveChild(row.SelectSingleNode("th[8]"));
        first = false;
    }
    else
    {
        row.RemoveChild(row.SelectSingleNode("td[10]"));
        row.RemoveChild(row.SelectSingleNode("td[9]"));
        row.RemoveChild(row.SelectSingleNode("td[8]"));
    }
}
