btw, you can leave out the ".Item" part, as it's a default property. So "Attributes[0]" would be sufficient. > // this returns correct first attribute's value > > Memo1.Lines.Add(doc.DocumentElement.FirstChild.Attributes.Item[0].NodeValue); > > // this returns correct first element's name > Memo1.Lines.Add(doc.DocumentElement.FirstChild.FirstChild.NodeName); > // this returns nothing !!! > Memo1.Lines.Add(doc.DocumentElement.FirstChild.FirstChild.NodeValue); Perhaps it contains whitespace? It's possible that the XML parser creates more than one text node. Do you have an excerpt of your XML file? This would be very helpful. - Sebastian _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
