I am using following code to read 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();

But i dont know how read the wp:comment with my above code…can anyone help me how to do this??

Answer 1

You haven’t said what you want to do with the data, which makes the question hard to answer. You also haven’t shown where the wp namespace alias is defined, but hey…

You want something like this, within your Select call:

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

I find it helpful to give static methods within the domain objects which can perform the transformation from XElement – it keeps things clearer.

FromXElement would then be something like:

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