Need VBScript function to return formatted string based on parameters

This is probably a pretty basic function, but i've been having all kinds of trouble with syntax.  I need a function to be able to accept a value, and a name, then return a string based on the value not being null.  If the value is null, then the string needs to add 'clear="true"', and also remove the cdata tags.  Below is some psuedocode to give you an idea of what i'm after.  Thanks.


Function printattribute(value, name)

if len(value) < 1 Then

f.WriteLine(Chr(9)+Chr(9)+Chr(9)+"<attribute clear=""true"" name=""+name+""></attribute>")

else 
f.WriteLine(Chr(9)+Chr(9)+Chr(9)+"<attribute name=""+name+""><![CDATA["+value+"]]></attribute>")
end if

End Function

'calling the functions
printattribute(watermelon,fruit)
printattribute("",fruit)

Open in new window

* there is a difference between an empty string and a Null value
* You should be passing strings to the function.
Example:
printattribute("watermelon", "fruit")

Open in new window

* Normally, I would expect a function to return some value.

The following is VB.net  -  the biggest difference is using "" to embed a " in string converted function to string as function wasn't returning a value .

    Private Sub printattribute(value, name)


        If Len(value) < 1 Then

            MsgBox(Chr(9) & Chr(9) & Chr(9) & "<attribute clear=""true""" & name & " = " & name & """><attribute>")

        Else
            MsgBox(Chr(9) & Chr(9) & Chr(9) & "<attribute name=""" & name & """><![CDATA[" & value & "]]></attribute>")
        End If

    End Sub
    Public Sub main()

        'calling the subroutine
        printattribute("watermelon", "fruit")
        printattribute("", "fruit")
    End Sub

ok the syntax appears to be working, but I somehow need to return that string generated by the sub, the msgbox does me no good.

This should handle the return of the result.

wscript.echo printattribute("watermelon", "fruit")
wscript.echo printattribute("", "fruit")

Function printattribute(value, name)
    If Len(value) < 1 Then
        printattribute = Chr(9) + Chr(9) + Chr(9) + "<attribute clear=""true"" name=""" + name + """></attribute>"
    Else 
       printattribute = Chr(9) + Chr(9) + Chr(9) + "<attribute name=""" + name + """><![CDATA[" + value + "]]></attribute>"
    End If
End Function
