我正在使用以下代码来读取 xml..

XDocument xDoc = XDocument.Load("willowcreekassociationblog.wordpress.xml");

        var list = xDoc.Descendants("Occurrence")
        .Select(o => new List.XMLList
        {
            title = (string)o.Element("title"),
            URL = (string)o.Element("link"),
            Descr = (string)o.Element("Description"),
            StartDate = (DateTime)o.Element("pubdate"),
        })
        .ToList();

但我不知道如何使用上面的代码阅读 wp:comment...谁能帮助我如何做到这一点？？

Answer 1

你没有说你想对数据做什么，这使得这个问题很难回答。您还没有显示 wp 命名空间别名的定义位置，但是嘿...

您希望在您的Select 电话中 像这样：

Comments = o.Elements(wp + "comment")
            .Select(comment => Comment.FromXElement(comment))
            .ToList();

我发现在可以执行从XElement 转换的域对象中提供静态方法很有帮助 - 它使事情更清晰。

FromXElement 将类似于：

public static Comment FromXElement(XElement x)
{
    return new Comment((int) x.Element(wp + "comment_id"),
                       (string) x.Element(wp + "author"),
                       ...);
}
