Answer 1

A little XML and and a CROSS APPLY
Option 1: Without a Split/Parse Function
Declare #YourTable table (Col1 varchar(25),col2 varchar(25))
Insert Into #YourTable values
('abc,def','xyz,xyz'),
('abc1,def1','xyz1,xyz1')
Select col1 = B.RetVal
,col2 = A.col2
From #YourTable A
Cross Apply (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(A.Col1,',','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as X
Cross Apply x.nodes('x') AS B(i)
) B
Returns
col1 col2
abc xyz,xyz
def xyz,xyz
abc1 xyz1,xyz1
def1 xyz1,xyz1
Option 2: with a Split/Parse Function
Select col1 = B.RetVal
,col2 = A.col2
From #YourTable A
Cross Apply [dbo].[udf-Str-Parse](A.col1,',') B
The UDF if interested
CREATE FUNCTION [dbo].[udf-Str-Parse] (#String varchar(max),#Delimiter varchar(10))
Returns Table
As
Return (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(#String,#Delimiter,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as X
Cross Apply x.nodes('x') AS B(i)
);
--Thanks Shnugo for making this XML safe
--Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
--Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')
--Select * from [dbo].[udf-Str-Parse]('this,is,<test>,for,< & >',',')

Answer 2

Here is another example:
;WITH A(Col1,col2)AS(
SELECT 'abc,def','xyz,xyz' UNION all
SELECT 'abc1,def1','xyz1,xyz1'
)
SELECT d.n,a.col2 FROM a
CROSS APPLY(VALUES(CONVERT(XML,'<n>'+REPLACE(col1,',','</n><n>')+'</n>'))) c(x)
CROSS APPLY(SELECT y.n.value('.','varchar(10)') FROM c.x.nodes('n') y(n)) d(n)
n col2
---------- ---------
abc xyz,xyz
def xyz,xyz
abc1 xyz1,xyz1
def1 xyz1,xyz1
