pageextension 50100 CustomerListExt extends "Customer List"
{
    trigger OnOpenPage();
    var
        xmlDoc: XmlDocument;
        xmlDec: XmlDeclaration;
        xmlElem: XmlElement;
        xmlElem2: XmlElement;
        TempBlob: Record TempBlob Temporary;
        outStr: OutStream;
        inStr: InStream;
        TempFile: File;
        fileName: Text;
    begin
        xmlDoc := xmlDocument.Create();
        xmlDec := xmlDeclaration.Create('1.0', 'UTF-8', '');
        xmlDoc.SetDeclaration(xmlDec);

        xmlElem := xmlElement.Create('root');
        xmlElem.SetAttribute('release', '2.1');

        xmlElem2 := XmlElement.Create('FirstName');
        xmlElem2.Add(xmlText.Create('Max'));

        xmlElem.Add(xmlElem2);
        xmlDoc.Add(xmlElem);

        // Create an outStream from the Blob, notice the encoding.
        TempBlob.CreateOutStream(outStr, TextEncoding::UTF8);

        // Write the contents of the doc to the stream
        xmlDoc.WriteTo(outStr);

         // From the same Blob, that now contains the XML document, create an inStr
        TempBlob.CreateInStream(inStr, TextEncoding::UTF8);

        // Save the data of the InStream as a file.
        File.DownloadFromStream(inStr, 'Export', '', '', fileName);
    end;
}
