XML Schema with same named Tables?

David++

Dear List,

Is it possible to have a schema with tables of the same name? I need to
build an XML document based on the following schema -

<?xml version="1.0" encoding="utf-8"?>

This schema has elements of the same name. When I come to populate my
DataSet tables with data it is not possible to discriminate between the
tables with the same name? Is this correct?

For example, if I want to create a new row of data for the 'Data' table
belonging to the PriceMatrix I would write -

DataRow dr = dsPricing.Tables["Data"].NewRow();

dr["Price_desc"] = jobtype;
dr["Prgr_code"] = sponsor;

dsPricing.Tables["Data"].Rows.Add(dr);
dsPricing.AcceptChanges();

But how do the different tables called "Data" get kept seperate?

Thanks for any helps,

David

I don't believe that you can create a DataSet out of a schema like that. You
may be stuck treating it like XML.
