hierarchical xml by DataSet()->WriteXml()

I'm playing with web-based front-end for hierarchical db in mssql2K.
So far my tables have 3 levels. I'm wonder how to store such hierarchical
trees outside (xml format).
DataSet()->WriteXml() method uses "2D" or flat dataset. How to create
tree-like xml?

You should look at either the FOR XML clause or the SQLXML 3.0 annotated
schemas.
Best regards
