Problem with sp_xml_preparedocument and ntext

Hi
I am trying to read by means of sp_xml_preparedocument a document XML stored
in a variable ntext, but this gives me the following error:
XML parsing error: Switch from current encoding to specified encoding not
supported.
Example XML:
<?xml version="1.0" encoding="ISO-8859-1"?>
<DA><USU tbxp1_varchar1="Sandra Damarid" /></DA>
It is possible to do compatible unicode with xml with encoding:
sp_xml_preparedocument + ntext + encoding
Thank
Cristiánntext requires the encoding to be UCS-2 or UTF-16. You need to do the
conversion on the mid-tier before sending it to sp_xml_preparedocument.
Alternatively, ISO-8859-1 is a 1-byte encoding. Use text instead and a
server code page that implies ISO-8859-1 encoding.
Best regards
Michael

Ok, test with UTF-16 and good, but testing XML in SQL Server 2005, does not
accept UTF-16 but yes UTF-8, ?You Know Why?
XML --> UTF-16 '

that work, but not thist:

<COB><DET Estado="Sandra Damarid" Origen="Vasquez" /></COB>'
why? N-> unicode and UTF-8 idem or not?

declare @.XmlInfo xml

<COB><DET Estado="Sandra Damarid" Origen="Vasquez" /></COB>'
This works because character data is expected to be single-byte.
declare @.XmlInfo xml
set @.XmlInfo= '<?xml version="1.0" encoding="UTF-8"?>
<COB><DET Estado="Sandra Damarid" Origen="Vasquez" /></COB>'
In other words, if the encoding is UTF-8, the string holding it has to be
varchar ('<xml...>'); and if the encoding is UTF-16, then the string holding
it has to be nvarchar (N'<xml...>')

need to pass it 8 bit data. If you say it's utf-16 you need to give it 16
bit data. In your example you prefix the string with an N which means the
string is Unicode so the parser parses Unicode data. When it runs into your
declaration that says it's utf-8 it is already parsing utf-16 so it errors
out because its is doing the wrong thing.
