Load XML from ADO Recordset

Hi all

I have a asp.net application which calls a web service
via a wdsl file which retrieves an XML String.

The XML String is from a adodb recordset saved as via a
stream.

Dim oRS as New ADODB.Recordset
Dim oStream as New ADODB.Stream
Set oRS = oCnn.Execute(sSQL)
'Save recordset as XML
oRS.Save oStream, adPersistXML
sXML = oStream.ReadText

In the ASP.Net application I retrieve the sXML via the
web service without any problems but when I try and load
to an XML document, nothing is loaded.

Dim xmlDoc As New XmlDocument
xmlDoc.LoadXml(sXML)

The xmlDoc remains empty.

I have been scratching my head on this for a couple of
hours and I am sure it's probably simple but would
appreciate any help.

Regards

Hi Mac,

Could you give us a little more detail or code?

It would help to have a sample of the string that you are getting into sXML
to analyze why the XML document doesn't like it. I assume that the XML is
well-formed.

How did you test that xmlDoc was empty?

Thanks,

Ken
 
Hi Ken

Thanks for your reply

I have attached examples of the code and xml that is
produced.

Any help would be really appreciated.

The XML is produced by a VB6 dll on a remote server using
the following code:

Public Function ReturnData() as String
Dim oCnn As New ADODB.Connection
Dim oStream As New ADODB.Stream
Dim oRS As New ADODB.Recordset

oCnn.ConnectionString = SQL_CONNECTION_STRING
oCnn.Open

oRS.CursorLocation = adUseClient
Set oRS = oCnn.Execute("SELECT .....")

'Save recordset as XML
oRS.Save oStream, adPersistXML

ReturnData = oStream.ReadText

Set oStream = Nothing
Set oRS = Nothing
Set oCnn = Nothing


End Function

The XML string is as follows

<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'

/>
</rs:data>
</xml>

In the ASP.Net app, I have registered the web service and
in the function call it as follows

Dim sXML as String
Dim xmlDoc As XmlDocument
Dim oWeb As New SoapEMEA.SunLink
sXML = oWeb.ReturnData()
'Load XML string into XML Doc
xmlDoc.LoadXml(sXML)

Now I could be really stupid (my girlfriend thinks so)
but I have tested to see if the xmlDoc has any data by
looking at xmlDoc.value.

As far as I can tell, it hasn't been loaded.

Help?

Hi Mac,

I was able to emit the XML you provided via a Web service (as a string),
capture it into an XmlDocument and confirm that the XML is in there. I wrote
it to the Output/Debug window.

Here's the code I used:

Private Sub Page_Load _
(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles MyBase.Load
Dim strXML As String
Dim xmlws As New xmlsrver
strXML = xmlws.ServeXML
Dim xmlDoc As New XmlDocument
xmlDoc.LoadXml(strXML)
Debug.Write(xmlDoc.OuterXml)
End Sub
 
Also, I tried it with and without the XML prologue and it worked.

<?xml version="1.0" encoding="utf-8" ?>
 
Hi Ken

Thanks for your reply. If anything has come out of this
is that I now know how to check an XML document in .net.

Thanks for your time, it is appreciated

Mac
