Is it possible to control the node style that XslTransform uses to output
XML?
Not directly on the XslTransform class, but there is a way (see below).
: : but if I use the XslTransform class I get
<mySchema rdf:resource='fred'></mySchema>
Unfortunately, my RDF parser doesn't like the second form,
This is a bug in the RDF parser. The Infoset represented by both
serializations is identical.
The reason XSLT doesn't address this is that the particulars of the
XML syntax are irrelevant to the document's content (i.e., it doesn't
matter whether double-quote or single-quote is used to delimit the
attribute values, or empty tags are rendered one way or another).
: : if it's possible to tell XslTransform to use the shortened notation?
An XmlTextWriter can be wrapped around the output from
XslTransform's Transform( ) method. This XmlTextWriter
can intercept calls to the WriteFullEndElement( ) method,
which XslTransform uses, and replace them with calls to
WriteEndElement( ). WriteEndElement( ) will produce the
shortened end tag when the element has no content.
Here is the code,
- - - XmlTextWriterEE.cs (complete)
using System;
using System.IO;
using System.Xml;
/// <summary>
/// Wrapper that forces shortened empty element end tags to
/// be rendered when possible.
/// </summary>
public class XmlTextWriterEE : XmlTextWriter
{
public XmlTextWriterEE( TextWriter sink) : base( sink) {;}
public override void WriteFullEndElement() {
base.WriteEndElement();
}
}

The way this might work with an XslTransform, named transformerObj,
would be to wrap some TextWriter (in this example, I wrap the Console
output stream, i.e., stdout).
transformerObj.Transform( xmlDoc.CreateNavigator,
null, new XmlTextWriterEE( Console.Out) );
The XmlTextWriterEE silently intercepts calls that instruct it to write
a full end tag (for instance, to be more compatible with HTML) and
redirects them to the method that'll write out a shortened end tag
for empty elements.
