C# 3.0 and XLinq

I have just been playing around a little with C#3.0 with XLinq trying to see how easy it would be to parse a simple xml document and create a list of strongly type objects out.

I had fun doing this and I will show you what I was doing so that you can either:
a) learn a little of what I learnt
b) tell me where I am going wrong, i.e, if there is a simpler method.

The XML file I am trying to parse is the MusizMox Style XML Document http://musicmoz.org/xml/musicmoz.lists.styles.xml:

<name>A Cappella</name>

And I want to produce a List of Name and Categories.

First I created a class as follows:
public class TagCategory
public string Name
get{return name;}
set{name = value;}

public string Category
get{return category;}
set{category = value;}

private string name;
private string category;

This is just a really simple class that holds the tag name and the category of the style.

Now comes the interesting part. The C#3.0 bit. I used XLinq with this, it is only a couple of lines, but it seems to be pretty cool.

Firtly I need to load the XML file, which is simple enough:
XDocument xdoc = XDocument.Load("musicmoz.lists.styles.xml");
XElement root = xdoc.Element("musicmoz");

Now that it is loaded I simple declare a List and run some XLinq as follows:

List t = new List(
a => new TagCategory{ Name = a.Element("name").Value,
Category = a.Element("category").Value}

What I can tell is happening is that we are looking at the root element and pulling back all the "style" elements, then for each element Select all of them but return a new TagCategory using object initilaizers for the Name and the Category class properties.

Clear as mud! :)

Any questions let me know and I will try and answer them :) paul.kinlan@gmail.com
