Parsing through an XML file using a randomly generated integer

This has absolutely stumped me. I have an XML file which is basically a list of items that my program will be using in the game, each item has an associated ID such as

<Items>
<Item ID ="1">
  <Name>Food</Name>
  <Price>1 copper</Price>
 </Item>
</Items>

How can I write my code so that I can parse through the XML using that random integer? Once I find the correct ID for that integer then I will get the elements from the XML file and my game will then use them.

Thanks for any help you can give.

With Linq to Xml you can select item element which have ID attribute equal value to your integer id variable:

var xdoc = XDocument.Load(fileName);
var item= xdoc.Descendants("Item")
              .FirstOrDefault(i => (int)i.Attribute("ID") == id);

Now if element with specified ID exists (i.e. item not null) you can write all it's elements value to Dictionary<string, string> with element name as key and element value as value:

if (item != null)   
{
    settings = item.Elements()
                   .ToDictionary(e => e.Name.LocalName, e => (string)e);   
}

Usage of settings dictionary:

if (settings.ContainsKey("Name"))
    name = settings["Name"]; // if id == 1 then name will be "Food"
