How to create an XML file using TXML Document in Delphi 7

I have used the following code to create the XML Document :

procedure TForm1.btnCreateXMLClick(Sender: TObject);
  var
   rootName:string;
  childName:string;
  attrChild:string;
   iXml: IDOMDocument;
  iRoot, iNode, iNode2, iChild, iAttribute: IDOMNode;
begin
  XMLDoc.Active:=false;
   XMLDoc.XML.Text:='';
   XMLDoc.Active:=true;
    XMLDoc.FileName:='C:\Documents and Settings\a\Desktop\New Text Document.xml';
     iXml := XmlDoc.DOMDocument;
   //iRoot:=iXml.documentElement(iXml.createElement('xml'));
    iRoot := iXml.appendChild(iXml.createElement ('xml'));
     // node "test"
     iNode := iRoot.appendChild (iXml.createElement ('test'));
      iNode.appendChild (iXml.createElement ('test2'));
   iChild := iNode.appendChild (iXml.createElement ('test3'));
    iChild.appendChild (iXml.createTextNode('simple value'));
     iNode.insertBefore (iXml.createElement ('test4'), iChild);

   // node replication
     iNode2 := iNode.cloneNode (True);
  iRoot.appendChild (iNode2);

    // add an attribute
      iAttribute := iXml.createAttribute ('color');
        iAttribute.nodeValue := 'red';
      iNode2.attributes.setNamedItem (iAttribute);

    // show XML in 开发者_如何学运维memo
      memXMLOutput.Lines.Text:=FormatXMLData(XMLDoc.XML.Text);
   end;

I get the output in memXMLOutput but the XML document does not show the output when seen in Notepad ot IE. where is the problem? Thanks in advance

Remove this:

XMLDoc.FileName:='C:\Documents and Settings\a\Desktop\New Text Document.xml';

and add something like this after the code is done creating the XML document:

XMLDoc.SaveToFile('C:\Documents and Settings\a\Desktop\New Text Document.xml');
