MORE INFORMATION

In an XML EXPLICIT mode, under normal conditions, if an attribute that appears in the xmltext element conflicts with an attribute that is retrieved on the same element level, the attribute in xmltext is ignored and overwritten. Under certain conditions with DBCS, however, the conflict attribute is not overwritten, but is instead duplicated. This produces XML that is not well-formed.

To reproduce this behavior, create a table, insert a row, and query the table as follows:

create table T1 (F0 int primary key, F1 TEXT collate Japanese_CI_AS)
go
insert into T1 values (111, '<elt1 att0="222" att1="’"><elt2 att2="’" /></elt1>')
go
select 1 as TAG, 0 as parent, F1 as [elt1!1!!xmltext], F0 as [elt1!1!att0] from T1 for xml explicit

The following is returned

-- [INCORRECT RESULT] - att0 is not overwritten.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 
<elt1 att0="111" att0="222" att1="’"><elt2 att2="’" /></elt1>

when the expected result should be as follows:

-- [EXPECTED  RESULT] - att0="222" is overwritten with att0="111"
