DataSet to XML

I have data coming from SQL Server and need to write out some XML. I
have a schema(xsd) for this XML file. Right now I am bringing in the
DataSet and writing out the elements and attributes myself using
xmltextwriter to match schema without really using the xsd at the time
of writing.

The file I create validates but I was wondering is there a better way?
I see things like inferschema method off of dataset, can this be used?
How do you map columns in a dataset with elements and attributes in
the schema? I know dataset.WriteXmL will write XML but that match my
schema. Appreciate any help!

Thanks,
Joe

I find it a bit hard to grasp your problem - you want to write out the
DataSet as
xml - and you want it to validate against your schema - but you don't want
to
use the dataset.WriteXml() that actually writes out conforming xml !?

Is it speed/other performance issues you're troubling with?

Sorry, let me clarify...as I mistyped "I know dataset.WriteXML will
write XML but that DOESN'T match my schema".

dataset.writexml would be great...but how do you get it to write xml
based on a existing schema? Is there a way to associate an existing
schema and map my columns in the dataset to elements/attributes and
then call the WriteXml method?

I think you are not framing your question quite right. Validation based on a
schema happens during the reading, not writing.

A truely wonderful free reference is the sample chapter from Bob
Beauchemin's
Essential ADO.Net
