    <p>You use two other classes in MSXML to write out XML properly encoded to an output stream.</p> <p>Here is my helper method that writes to a generic IStream:</p> <pre><code>class procedure TXMLHelper.WriteDocumentToStream(const Document60: IXMLDOMDocument2; const stream: IStream; Encoding: string = 'UTF-8'); var writer: IMXWriter; reader: IVBSAXXMLReader; begin { From http://support.microsoft.com/kb/275883 INFO: XML Encoding and DOM Interface Methods MSXML has native support for the following encodings: UTF-8 UTF-16 UCS-2 UCS-4 ISO-10646-UCS-2 UNICODE-1-1-UTF-8 UNICODE-2-0-UTF-16 UNICODE-2-0-UTF-8 It also recognizes (internally using the WideCharToMultibyte API function for mappings) the following encodings: US-ASCII ISO-8859-1 ISO-8859-2 ISO-8859-3 ISO-8859-4 ISO-8859-5 ISO-8859-6 ISO-8859-7 ISO-8859-8 ISO-8859-9 WINDOWS-1250 WINDOWS-1251 WINDOWS-1252 WINDOWS-1253 WINDOWS-1254 WINDOWS-1255 WINDOWS-1256 WINDOWS-1257 WINDOWS-1258 } if Document60 = nil then raise Exception.Create('TXMLHelper.WriteDocument: Document60 cannot be nil'); if stream = nil then raise Exception.Create('TXMLHelper.WriteDocument: stream cannot be nil'); // Set properties on the XML writer - including BOM, XML declaration and encoding writer := CoMXXMLWriter60.Create; writer.byteOrderMark := True; //Determines whether to write the Byte Order Mark (BOM). The byteOrderMark property has no effect for BSTR or DOM output. (Default True) writer.omitXMLDeclaration := False; //Forces the IMXWriter to skip the XML declaration. Useful for creating document fragments. (Default False) writer.encoding := Encoding; //Sets and gets encoding for the output. (Default "UTF-16") writer.indent := True; //Sets whether to indent output. (Default False) writer.standalone := True; // Set the XML writer to the SAX content handler. reader := CoSAXXMLReader60.Create; reader.contentHandler := writer as IVBSAXContentHandler; reader.dtdHandler := writer as IVBSAXDTDHandler; reader.errorHandler := writer as IVBSAXErrorHandler; reader.putProperty('http://xml.org/sax/properties/lexical-handler', writer); reader.putProperty('http://xml.org/sax/properties/declaration-handler', writer); writer.output := stream; //The resulting document will be written into the provided IStream // Now pass the DOM through the SAX handler, and it will call the writer reader.parse(Document60); writer.flush; end; </code></pre> <p>In order to save to a file i call the <strong>Stream</strong> version with a <strong>FileStream</strong>:</p> <pre><code>class procedure TXMLHelper.WriteDocumentToFile(const Document60: IXMLDOMDocument2; const filename: string; Encoding: string='UTF-8'); var fs: TFileStream; begin fs := TFileStream.Create(filename, fmCreate or fmShareDenyWrite); try TXMLHelper.WriteDocumentToStream(Document60, fs, Encoding); finally fs.Free; end; end; </code></pre> <p>You can convert the functions to whatever language you like. These are Delphi.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
