Hi All,

I am using this sp in sQL to produce an XML document:

SELECT  contract_id , Customer_id
FROM contracts
ORDER BY contract_id
FOR XML AUTO

Using VB.NET 2005 how can i get this result set and transform it into an XSL document using VB?
I haven't written in VB in years so please provide all the code (include declarations, general database connection, etc...)

Thanks a Million

MoreThanDoubled,

Since you are already generating the XML string using SQL code, this issue is really just a simple creating of XML in .NET from a string; therefore, one solution is to use System.Xml.XmlDocument and its LoadXml() method to read the string into XML.

http://www.vbdotnetheaven.com/UploadFile/bulentozkir/XMLfileUsingXmlDocument04232005010454AM/XMLfileUsingXmlDocument.aspx

Here is one example of using XslTransform; however, note it is shown with XML and XSL both being files, so to combine with above you could write the XmlDocument generated to a file first.

http://support.microsoft.com/kb/300929/EN-US/

These were just handy articles on code already written, but I will try to work up another example.

Best regards,
Kevin

Here is an example from database read through XML output.
' http://www.connectionstrings.com/
Const strConn As String = "Data Source=localhost;Initial Catalog={{your_database}};User Id={{user}};Password={{password}};"

' Imports System.Text
' Note addition of root element to make a valid XML document
Dim sql As New StringBuilder()
sql.AppendLine("SELECT  contract_id , Customer_id")
sql.AppendLine("FROM Contracts AS Contract")
sql.AppendLine("ORDER BY contract_id")
sql.AppendLine("FOR XML AUTO, ROOT('Contracts')")

' Imports System.Data.SqlClient
Dim conn As New SqlConnection(strConn)
Dim cmd As New SqlCommand(sql.ToString(), conn)

' Open connection first
conn.Open()

' Imports System.Xml
Dim xmlIn As Xml.XmlReader = cmd.ExecuteXmlReader
Dim xmlOut As New Xml.XmlTextWriter("c:\temp\Contracts.xml", Encoding.UTF8)

' Imports System.Xml.Xsl
' XslTransform is deprecated in newer .NET
Dim xsl As New XslCompiledTransform()
xsl.Load("c:\temp\Stylesheet.xsl")
xsl.Transform(xmlIn, xmlOut)

' ...

' Close your connection and cleanup other references
conn.Close()

Open in new window

Stylesheet.xsl
Contracts.xml
