如何使用anglesharp从HTML表中删除所有行?

How is it possible to remove all rows from the HTML table using anglesharp?

我正在尝试删除表中的所有行.我'请阅读本文档，但是不会删除行.

I am trying to remove all rows in table. I've read this documentation, however, rows are not removed.

我的代码如下:

public void DeleteRows(IElement table)
{
    foreach (var row in table?.QuerySelectorAll("tr"))
    {
        row.Remove();
    }
    var lengthAfterDeletion = table?.QuerySelectorAll("tr")?.Length;
}

推荐答案

我认为我们在此期间已经解决了这一问题(请参见 https://github.com/AngleSharp/AngleSharp/issues/838 ).

I think we figured it out in the meantime (see https://github.com/AngleSharp/AngleSharp/issues/838).

仅供以后参考(以防其他人遇到相同的问题，这很容易发生):

Just for future reference (in case somebody else runs into the same problem, which happens quite easily):

public void DeleteRows(IElement table)
{
    var rows = table?.QuerySelectorAll("tr").ToArray();
    foreach (var row in rows)
    {
        row.Remove();
    }
    var legnthAfterDeletion = table?.QuerySelectorAll("tr")?.Length;
}

关键是在更改DOM之前获取结果的静态快照.因此，来自LINQ的 .ToArray()可以应用于任何迭代器.

The key is to get a static snapshot of the result before changing the DOM. Hence the .ToArray() which comes from LINQ and can be applied to any iterator.
