output xml with attributes

Question

Hello,

How do I get this output?

<MSRP currency="USD">10.00</MSRP>

writer.WriteElementString("MSRP", Convert.ToString(q.ItemPrice1));

writer.WriteAttributeString("currency", "MSRP", "USD");

this is the error:

Token StartAttribute in state Content would result in an invalid XML document.

Answer 1

writer.WriteStartElement( "MSRP" );
writer.WriteAttributeString( "currency", "USD" );
writer.WriteString( q.ItemPrice1.ToString() );
writer.WriteEndElement();

When you call WriteElementString it writes the entire element all at once - no chance to later add attributes. You have to open the element with WriteStartElement...then close it with WriteEndElement.

Answer 2

I believe this will do the trick.

writer.WriteStartElement("MSRP");
writer.WriteAttributeString("currency", "USD");
writer.WriteValue("10.00");
writer.WriteEndElement();
