XML format problem

Question

Hello all,

I have a field 'Tax' of data type 'xml' in my table. On button click data saved successfully in 'Tax' field. I want to retrieve that data and bind it to a gridview.

 I use this to bind :

DataSet ds = new DataSet();

 ds.ReadXml(s);

 GridView1.DataSource = ds.Tables[0].DefaultView;

But it is giving a runtime error "Illegal characters in path".

I am using following xml format:

<Tax>

<TaxData>

<Name>VAT</Name>

<Rate>5.00</Rate>

</TaxData>

<TaxData>

<Name>Other Tax</Name>

<Rate>6.00</Rate>

</TaxData>

<TaxData>

<Name>Custom Tax</Name>

<Rate>6.00</Rate>

</TaxData>

</Tax>
