Hi David,
I'd get the dataset's XML with
string xml = dataset1.GetXml();
and transform that xml into my desired output using XSLT. This way you can
always change your putput without having to change your program's code.
Beside that, this way you can easily ensures that your XML is valid.
To use XSLT youe have to do something like this:
XPathNavigator xpath = doc.CreateNavigator(); //doc is the XmlDocument you
got from dataset1.GetXml()
XmlResolver xmlResolver = null;
MemoryStream ms = new MemoryStream();
XsltArgumentList args = new XsltArgumentList();
NameTable nt = new NameTable();
XmlNamespaceManager nsm = new XmlNamespaceManager(nt);
XmlValidatingReader xmlR = new XmlValidatingReader([your XSLT code here],
XmlNodeType.Document, new XmlParserContext(null, nsm, null,XmlSpace.None));
XslTransform xslt = new XslTransform();
xslt.Load(xmlR, null, null);
xslt.Transform(xpath, args, ms, xmlResolver);
After that ms carries the output XML you wanted to get. You could save it
into a file or whatever.
To load XML into a dataset you have to do the same, but the input is the XML
you can load from wherever and after transforming it using XSLT you can use
dataset1.ReadXml(ms);
This is the way I'd preferr as the most professional. Hope this helps.
For a brief intruduction into XSLT, try

Hello.
What is the optimal way to manualy import/export data from/to XML file
to/form my DataSet?
What I wnat:
1. To add some data (records) from XML file to may dataset.
2.. To add some data (records) from dataset to may XML file.
For example:
Table structure:
ID int Primary Key
FirstName VarChar (15)
LastName VarChar (15)
Age int
XML file structure:
<Pesrons>
<ID> </ID>
<FirstName> </FirstName>
<LastName> </LastName>
<Age> </Age>
</Pesrons>
If it's poseble show me little example or some demo please.
