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 learntb) 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:<musicmoz><style><name>A Cappella</name><category>Styles/Vocal/A_Cappella</category></style><style><name>Acadian</name><category>Styles/World/Cajun/Acadian</category></style>......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(root.Elements("style").Select(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
