.NET Regular Expression to split multiple words or phrases

I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one开发者_如何学Python element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring?

Private m_Reg As Regex
m_Reg = New Regex("([^""^\s]+)\s*|""([^""]+)""\s*")
Dim rezsplit = m_Reg.Split(criteria)

Alan's answer is correct. Using his pattern we could use LINQ to filter the Split results or we could use Matches as he suggested.

Dim input As String = "Islands of Adventure ""Disney Land"" Universal Studios"
Dim pattern As String = "(?<Value>[^""\s]+)|""(?<Value>[^""]+)"""
Dim result = Regex.Split(input, pattern).Where(Function(s) s.Trim <> "")

Console.WriteLine("Split Result:")
For Each s In result
    Console.WriteLine(s)
Next

Console.WriteLine("Matches:")
For Each m As Match In Regex.Matches(input, pattern)
    Console.WriteLine(m.Groups("Value").Value)
Next

''# to get string arrays use either of these instead
Dim splitArray As String() = Regex.Split(input, pattern) _
                              .Where(Function(s) s.Trim <> "") _
                              .ToArray()
Dim matchArray As String() = Regex.Matches(input, pattern).Cast(Of Match) _
                                  .Select(Function(m) m.Groups("Value").Value) _
                                  .ToArray()

Use Matches instead of Split and you won't have to worry about that. You can simplify the regex, too:

m_Reg = New Regex("""([^""]+)""|[^""\s]+")

EDIT: I forgot to deal with the problem of scraping off the quotes. This will make it easier:

m_Reg = New Regex("""(?<Value>[^""]+)""|(?<Value>[^""\s]+)")

Now, whichever alternative matches, the desired text can be found in the group named "Value".
