How to split string based on either space or tab delimitation?

Question

I'm trying to split a string into 4 fields.  The strings sometimes have space delimitation and sometimes have tab delimitation.  Is there any way to do this in a SELECT, or do I need a couple staging tables, or what?
I'm trying to work with this.
Select PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),4) Date,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),3) ID,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),2) Rank1,
PARSENAME(replace(replace(replace(replace([Column 0],' ','<>'),'><',''),'char(9)',' '),' ','.'),1) Rank2
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

This is similar thread that someone posted a week ago
Split delimited string into separate columns
based on space
My solution was, using a user defined function to split the text:
Use Master
Go
CREATE FUNCTION dbo.udf_SplitString(@InputVal VARCHAR(200), @Delimiter CHAR(1))
RETURNS @Items TABLE (RowNo TINYINT, ITEM VARCHAR(100))
As
BEGIN
DECLARE @FieldLen TINYINT = 0, @FieldEnum TINYINT = 0, @TempItem VARCHAR(100) = '', @ItemLoop TINYINT = 1
SET @FieldLen = LEN(@InputVal)
WHILE @FieldEnum <= @FieldLen
BEGIN
IF (SUBSTRING(@InputVal, @FieldEnum + 1, 1) = @Delimiter OR @FieldEnum = @FieldLen) AND @TempItem <> ''
BEGIN
INSERT @Items (RowNo, Item)
VALUES (@ItemLoop, LTRIM(RTRIM(@TempItem)))
SET @TempItem = ''
SET @ItemLoop += 1
END
ELSE
BEGIN
IF SUBSTRING(@InputVal, @FieldEnum + 1, 1) <> @Delimiter
BEGIN
SET @TempItem = @TempItem + SUBSTRING(@InputVal, @FieldEnum + 1, 1)
END
END
SET @FieldEnum += 1
END
RETURN
END
Next, use the splited data to group based on requirements
DECLARE @AllData TABLE
[Column 0] VARCHAR(50)
INSERT INTO @AllData
VALUES('20150101 04559690 45 33')
INSERT INTO @AllData
VALUES('20150101 045595320 42 48')
INSERT INTO @AllData
VALUES('20150101 041198690 44 34')
INSERT INTO @AllData
VALUES('20150101 0455222130 41 49')
INSERT INTO @AllData
VALUES('20150101 554567450 40 51')
;WITH CTE
AS
SELECT
,Row_Number() OVER(PARTITION BY MainQry.[Column 0] ORDER BY MainQry.[Column 0]) As RowNo
FROM
@AllData As mainQry
CROSS APPLY (SELECT Item FROM Master.dbo.udf_SplitString(REPLACE(MainQry.[Column 0], CHAR(9), ' '), ' ')) As SubQry
SELECT
[Column 0]
,MAX(CASE WHEN RowNo = 1 THEN Item ELSE '' END) AS [DATE]
,MAX(CASE WHEN RowNo = 2 THEN Item ELSE '' END) AS [ID]
,MAX(CASE WHEN RowNo = 3 THEN Item ELSE '' END) AS [Rank1]
,MAX(CASE WHEN RowNo = 4 THEN Item ELSE '' END) AS [Rank2]
FROM
CTE
GROUP BY
[Column 0]
Output
Column 0 | DATE
| ID
| Rank1 | Rank2
20150101 0455222130
41 49
| 20150101
| 0455222130
| 41 | 49
20150101 554567450
40 51
| 20150101
| 554567450
| 40 | 51
20150101 041198690 44  34
| 20150101
| 041198690
| 44 | 34
20150101 045595320 42   48
| 20150101
| 045595320
| 42 | 48
20150101 04559690 45  33
