有一个用于示例教学大纲设计的 HTML。我正在开发一个设计教学大纲的 C# 程序。并且有一个添加列的机制进行编辑。为了将列的信息保存在 HTML 文件中，我想使用 C# 在每个 <td>...</td> 间隔中添加一个新的 <tr>...</tr>。如何选择 <tr>...</tr> 中的每个 <table align="center" cellpadding="2" cellspacing="2" class="table table-condensed table-bordered" id="evaluation_table1"> 间隔？

解决方法

尝试使用正则表达式匹配。举例：

            var html = "you html";
            Regex rx = new Regex(@"<tr.*?</tr>");
            foreach (Match match in rx.Matches(html))
            {
                int i = match.Index;
                html.Insert(i + 4,"<td></td>");
            }
