Unless you're taking some special care of XML structure, writing several
data sets into one XML would result in malformed XML document.
If you're fixing XML manually, look into ReadXml() overloads with
XmlReadMode argument and XmlReadMode.Fragment mode.
Again, it's up to you to find the right data set start and invoke ReadXml()
on it.

I don't see any advantages of that compared to normal file per data set
solution.
In fact, I do see a major disadvantage which is the need to overwrite the
entire file should you change even one record in one data set.
So I would suggest you don't do it.

Best regards,

Ilya
