How can I programmtically parse to get the "weather-type" value from this string

<value coverage="chance" intensity="light" weather-type="rain showers" qualifier="none">

I need to do this in VB.NET and return the value for the weather-type element

Any help would be appreciated
Thanks
JK

is this homework?

you could use Instr to find the start of  Weather type then add 14 to get the start position of the data.... after that you then need to copy all the c haracters until you find the next quote/ending quote

Dim startIndex As Integer = yourString.IndexOf("weather-type=") + 14
            Dim endIndex As Integer = yourString.IndexOf("""", startIndex)
            Dim result As String = yourString.Substring(startIndex, endIndex - startIndex)

Hi jk;

You could also use a regular expression to get the value as shown below.

' The string you wish to parse
Dim weatherStr As String = "Your Input String Here."
' Get the weather-type from the string
Dim weather = Regex.Match(weatherStr, "(?i)weather-type=""([^""]+)")
' Test to see if weather-type was in the string and if so access the value
If weather.Success Then
    Console.WriteLine(weather.Groups(1).Value)
End If
