Here is an example of parsing the XML input in stored procedure:
http:Q_23683642.html

In the C# code, you would just use the Command.Parameters.Add to add in a parameter of type XML and then pass in your value.  Guess you could just pass in a String parameter and as long as it is valid XML it should be converted to XML in the procedure since that is the input type.  For XML, the type in C# should be SqlTypes.SqlXml.

I am completly new to c#, could you help at the line level, should I write something like:

SqlParameter myParameter = new SqlParameter("@myXML", SqlDbType.Text);
myParameter.Direction = ParameterDirection.Input;
myParameter.Value= "'<UA> <i name="UserAgent1" /><i name="UserAgent2" /> <i name="UserAgent3" /></UA> '";
mycommand.Parameters.Add(myParameter);
...
execyte so_executesql @mycommand ...

Looks pretty good.  See my suggestions below.

If command type set to stored procedure, think you can just use mycommand.ExecuteNonQuery().
// I would stick with SqlDbType.Xml or SqlDbType.NVarChar here
SqlParameter myParameter = new SqlParameter("@myXML", SqlDbType.Xml);
myParameter.Direction = ParameterDirection.Input;
myParameter.Value = "<UA><i name="UserAgent1" /><i name="UserAgent2" /><i name="UserAgent3" /></UA>"; // Try without single quotes
mycommand.Parameters.Add(myParameter);

Hi mwvisa1,

If I call the SP like this:
exec SPName @UserAgentsXML='<UA> <i name=''UserAgent1" /><i name="UserAgent2" /> <i name="UserAgent3" /></UA>'

My first question is: is it 2 single or double quote for the UserAgent1, UserAgent2...etc strig?

Second, here is how my procedure looks like. Could you trouble shooting it as it is not working:
SET @n = 1
SET @params = N'@UAXML XML'

WHILE 1 = 1
 BEGIN
  SET @cmd = N'SET '+ CAST(@UserAgent AS NVARCHAR(256)) +' = @x.value(''(/UA)[' + CAST(@n AS NVARCHAR(3)) + ']'', ''nVARCHAR(256)'')'

  print 'cmd:'+isnull(@cmd,0)
  EXECUTE sp_executesql @cmd, @params, @UAXML = @UserAgentsXML  

  --print 'useragent:'+isnull(@UserAgent,0)
  IF @UserAgent IS NULL
     BREAK

  INSERT INTO table
  SELECT *
  WHERE c.AgentName=@UserAgent
 
  SET @n = @n + 1
END -- while

Thanks very much for your help,

Sorry here is the procedure code:
SET @n = 1
SET @params = N'@UAXML XML'

WHILE 1 = 1
 BEGIN
  SET @cmd = N'SET '+ CAST(@UserAgent AS NVARCHAR(256)) +' = @UAXML.value(''(/UA)[' + CAST(@n AS NVARCHAR(3)) + ']'', ''nVARCHAR(256)'')'

  EXECUTE sp_executesql @cmd, @params, @UAXML = @UserAgentsXML  

  IF @UserAgent IS NULL
     BREAK

  INSERT INTO table
  SELECT *
  WHERE c.AgentName=@UserAgent
 
  SET @n = @n + 1
END -- while

****The @UAXML.value(('/UA)[n]' part, I don't know how to write for the xml input as well. Please suggest. thanks
