c# - 如果 Html 文件没有结束“/tr”标记或“/td”标记，则 HTML 敏捷包无法完美读取该信息

Question

我正在使用 HTML Agility Pack 来解析 html 内容。我正在使用解析来提取表信息。有用。但是如果没有结束“/tr”标签或“/td”标签，那么它不会完美地解析该信息。（其中没有结束tr标签或td标签。）

由于您测试了我的另一个想法并且它不起作用，我认为您只有两个选择：

修改 HTML Agility Pack 以处理您的案例，或
自己填写缺失</tr>的s。

这是一个正则表达式，它可能会为您填充缺失</tr>的 s：

html = Regex.Replace(html, "<tr[^>]*>(?:(?!</?tr>|</tbody>|</table>).)*?(?=<tr[^>]*>|</tbody>|</table>)", "$&</tr>", RegexOptions.Singleline | RegexOptions.IgnoreCase);

（如果有人可以改进我的正则表达式，请随意。）

我还没有尝试过，但是添加此代码是否有帮助？

HtmlNode.ElementsFlags.Add("tr", HtmlElementFlag.Closed);
HtmlNode.ElementsFlags.Add("td", HtmlElementFlag.Closed);

我为 HTML agility Pack 编写了一个补丁，它应该能够处理所有可选的结束标签（尽管我现在允许在 a<p>中使用一个块）。

它还没有太多的测试方式，但你总是可以试一试。它附加到以下 Html Agility Pack 错误报告：http: //htmlagilitypack.codeplex.com/workitem/29218

你可以试试 HTML Tidy Tidy.NET。这似乎可以解决您的问题。
