well, yuo will be using some xml component. for example on using TXMLDocument (comes with delphi, see this:

procedure TForm1.FormCreate(Sender: TObject);
var xml:TXmlDocument; node:IXMLNode;
begin
  xml:=TXMLDocument.Create(self);
  xml.DOMVendor:=DomVendors.Vendors[1];// 0 is ms xml and it's stupid :D
  xml.LoadFromFile('c:\data.xml');
  xml.Active:=true;
  node:=xml.DocumentElement.ChildNodes.FindNode('SMTP_Email_Address');
  if node<>nil then showmessage(node.NodeValue)
               else showmessage('not found');
  xml.free;
end;

you will not be able to use teh default vendor in this case since it seems to have some issues swithing from default utf-8 encoding to utf-16. but since it's made by MS it is a "normal" thing :)

oh, you put that XML in a file called c:\data.xml. OR you place it in a stream and pass the stream to loadfromstream. OR you place it in astring and assign the xml.xml.text:=the string..

I put your code in the procedure for Button1.

But xml.LoadFromFile(ExtractFilePath(Application.ExeName)+'Test.xml');  gives an accessviolation.
Any ideas?

I already got the solution.
xml.DOMVendor:=DomVendors.Vendors[1];
had to be set to
xml.DOMVendor:=DomVendors.Vendors[0];

hm.. weird.
on my sistem xml.DOMVendor:=DomVendors.Vendors[0]; gives an error with the encoding. anyway, if it works, it's good so you can remove that line.

Thank you for your help.
The XML-file is used in Windows Vista to store E-mail accounts (*.oeaccount). Maybe that's why the 0 in stead of 1?
Anyway it works perfectly.

For other people who are interested in this code:
You should also add following units to the uses clause: XMLDOC, XMLIntf, XMLDom
