XML column compare in SQl server 2005

I want to compare two XML columns with multiple rows in SQL Server 2005.

Table structure is as below

CREATE TABLE [dbo].[UpdationLog](
    [LogID] [int] IDENTITY(1,1) NOT FOR REPLICATION NOT NULL,
    [CustID] [int] NOT NULL,
    [OldValue] [xml] NOT NULL,
    [NewValue] [xml] NOT NULL,
 CONSTRAINT [PK_UpdationLog] PRIMARY KEY CLUSTERED 
(
    [LogID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

INSERT INTO [dbo].[UpdationLog] VALUES
(1526,'<ccm CustID="1526" CustName="Teja" Address="Bangalore"/>','<ccm CustID="1526" CustName="Tejas" Address="Bengaluru"/>'),
(1245,'<ccm CustID="1245" CustName="Abhi" Address="Andhra"/>','<ccm CustID="1245" CustName="Abhilash" Address="Andra Pradesh"/>'),
(1145,'<ccm CustID="1145" CustName="Abhi" Address="Assam"/>','<ccm CustID="1145" CustName="Abhinandan" Address="Assam"/>')

I want to compare XML column OldValue and NewValue and display updated records.

Desired Output

|-------|-------------|---------------|------------
|CustID |   Attribute |     OldValue  | NewValue
|-------|-------------|---------------|---------
|1526   | CustName    |  Teja         | Tejas
|1526   | Address     | Bangalore     | Bengaluru
|1245   | CustName    |  Abhi         | Abhilash
|1245   | Address     |  Andhra       | Andra Pradesh
|1145   | CustName    |  Abhi         | Abhinandan
