通过表格的行和列的Html敏捷包环路 [英] Html Agility Pack loop through table rows and columns

问题描述

我有一个这样的表

<table border="0" cellpadding="0" cellspacing="0" id="table2">
    <tr>
        <th>Name
        </th>
        <th>Age
        </th>
    </tr>
        <tr>
        <td>Mario
        </td>
        <th>Age: 78
        </td>
    </tr>
            <tr>
        <td>Jane
        </td>
        <td>Age: 67
        </td>
    </tr>
            <tr>
        <td>James
        </td>
        <th>Age: 92
        </td>
    </tr>
</table>

和希望使用HTML敏捷性包解析它。我曾尝试code无济于事：

And want to use HTML Agility Pack to parse it. I have tried this code to no avail:

foreach (HtmlNode row in doc.DocumentNode.SelectNodes("//table[@id='table2']//tr"))
{
    foreach (HtmlNode col in row.SelectNodes("//td"))
    { 
        Response.Write(col.InnerText); 
    }
}

我是什么做错了吗？

What am I doing wrong?

推荐答案

我必须提供完整的XPath。我用萤火虫从建议由@Coda（ http://stackoverflow.com/a/3104048/1238850），我结束了这个code：

I had to provide the full xpath. I got the full xpath by using Firebug from a suggestion by @Coda (http://stackoverflow.com/a/3104048/1238850) and I ended up with this code:

foreach (HtmlNode row in doc.DocumentNode.SelectNodes("/html/body/table/tbody/tr/td/table[@id='table2']/tbody/tr"))
            {
                HtmlNodeCollection cells = row.SelectNodes("td");
                for (int i = 0; i < cells.Count; ++i)
                {
                    if (i == 0)
                    { Response.Write("Person Name : " + cells[i].InnerText + "<br>"); }
                    else {
                        Response.Write("Other attributes are: " + cells[i].InnerText + "<br>"); 
                    }
                }
            }

我相信这可以写成的方式比这更好的，但它是为我工作了。

I am sure it can be written way better than this but it is working for me now.
