I'm working on a hangman game for my 1st years final exam programming/analyst.

I basically have everything setup so it works but there is one thing that I am unable to accomplish.

My game will create an xml for each player where I will store that persons Won/Lost stats per difficulty selected.

XML example:

<?xml version="1.0" encoding="utf-16" ?>
  <Stats Difficulty = "Easy">
  <Stats Difficulty = "Medium">
  <Stats Difficulty = "Hard">

I was able to query the XML on element and attribute by doing the following:

Dim query As IEnumerable(Of XElement) = From q In UserXML.<Stats> _
                                                Where q.@Difficulty = Diff _
                                                Select q

If I output query.value I get the 2 values of the elements Won and Lost but they are concatenated.

For example, If I do this query on difficulty Easy then I get as outcome = 100

Could someone please tell me how I can assign the values of Won and Lost to existing variables so I can use them afterwards?

I can assing aliases to the select values but I'm unsure how to use them oustide the query.

This seems to work:
' Xml.
Dim myXml = <?xml version="1.0" encoding="utf-16"?>
                <Stats Difficulty="Easy">
                <Stats Difficulty="Medium">
                <Stats Difficulty="Hard">

' Query.
Dim query =
    From q In myXml.<UserStats>.<Stats>
    Where q.@Difficulty = "Easy"
    Select New With {
        .Won = q.<Won>.Value,
        .Lost = q.<Lost>.Value}

' First result.
Dim firstItem = query.FirstOrDefault()

' Won/lost values.
Dim won As Integer = Integer.Parse(firstItem.Won)
Dim lost As Integer = Integer.Parse(firstItem.Lost)

I used inline XML, but same idea.
