Question

I am reading an XML file using XDocument and loading it into classes. Each “site” node should be a class with the “tags” node being a List within it. I am having trouble loading the “tags” elements into the class as a List.

Here are the classes:

public class Site
{
    public string name;
    public string prefix;
    public List<Tag> tags;
}
public class Tag
{
    public string Name { get; set; }
    public string Column { get; set; }
}

This is the code that is loading XML data into the classes:

settings = XDocument.Load("settings.xml");
IEnumerable<Site> sites = settings.Descendants("site").Select(x => new Site()
{
   name = x.Element("name").Value,
   prefix = x.Element("prefix").Value,
   // How to load the "tag" elements into a List<Class>?
});

Using the following XML example:

<settings>
    <site>
        <name>name1</name>
        <prefix>prefix1</prefix>
        <tags>
            <tag column="col1">tag1</tag>
            <tag column="col2">tag2</tag>
            <tag column="col3">tag3</tag>
        </tags>
    </site>
    <site>
        <name>name2</name>
        <prefix>prefix2</prefix>
        <tags>
            <tag column="col1">tag1</tag>
            <tag column="col2">tag2</tag>
            <tag column="col3">tag3</tag>
        </tags>
    </site>
</settings>

Thanks.

Try this, at the location of your comment // How to load… : (untested)

tags = x.Element("tags").Elements("tag").Select(r => new Tag() { Column=r.Attribute("column"), Value = r.Value } );
