Parsing a XMLDocument in a DLL - A.V.

Hi all,

I have a DLL that downloads a XML document from a website or a file share and puts it into a TMemoryStream. I then create a TXMLDocument and load the XML from the stream. Like this:

    XMLDocument := TXMLDocument.Create(nil);
    try
      XMLDocument.LoadFromStream(streamXMLFile);
      XMLDocument.Active := true;

Next I need to get one value out of the XML file and carry on doing other stuff, but here comes my problem... When I try to access XMLDocument.DocumentElement I get an Access Violation and I can't figure out why. My code continues like this:

      FNewApplicationVersion := XMLDocument.DocumentElement.ChildNodes.FindNode('ApplicationVersion').Text;   <------ Throws exception
    except
      on E: Exception do begin
        ShowMessage('Error: ' + E.Message);
      end;
    end;

The exception I get is "Access Violation at address 00002000. Read of address 00002000"

My variable declarations look like this:
var
  streamXMLFile : TMemoryStream;
  XMLDocument : TXMLDocument;
  FNewApplicationVersion : String;

As I mentioned this is a DLL. The same code works fine in a normal application... Any ideas?
I have done the trick with including ActiveX in my uses clause and calling CoInitialize in the initialization section.

Best regards,
Marius
