SQL Server 2008再帰的cte文字列元の値を維持する置換

Question

ここで見つけた以前に実行された例を使用して、私は入手困難な固有の状況に立ち往生しました。

ここで適応コード

declare @RandomString table (ID int not null,ItemValue varchar(500) not null) 

insert into @RandomString(ID,ItemValue) 
values (1,'<Strings><B1>String1</B1><B2>String2</B2><B3>String3</B3><B4>String4</B4></Strings>') 

declare @SearchCharReplacement table (Original varchar(500) not null,Replacement varchar(500) not null) 

Insert into @SearchCharReplacement(Original, Replacement) 
values ('String1', 'abc'), ('String2', 'efg'), 
     ('String3', 'hij'), ('String4', 'klm') 

;With Replacements as (
select ID,ItemValue,0 as RepCount 
from @RandomString 
union all 
select ID,SUBSTRING(REPLACE(ItemValue,Original, Replacement),1,500),rs.RepCount+1 
from Replacements rs 
inner join @SearchCharReplacement scr on CHARINDEX(scr.Original,rs.ItemValue) > 0 
) 

, FinalReplacements as (
select ID,ItemValue,ROW_NUMBER() OVER (PARTITION BY ID ORDER BY RepCount desc) as rn 
from Replacements 
) 

update rs set ItemValue = fr.ItemValue 
from @RandomString rs 
inner join FinalReplacements fr on rs.ID = fr.ID and rn = 1 

select * from @RandomString 

結果が

<Strings><B1>abc</B1><B2>def</B2><B3>ghi</B3><B4>jkl</B4></Strings> 

私が本当に希望するすべてのヘルプは非常にいくつかの内部で

を高く評価している

<Strings><B1>String1|abc</B1><B2>String2|def</B2><B3>String3|ghi</B3><B4>String4|jkl</B4></Strings>
