Optimising XDocument to XDocument XSLT

c#, xslt, xslt-2.0

Solution

Rather than using strings to create the XDocument you can try passing in an XmlWriter created from the XDocument directly:

XDocument outputDoc = new XDocument();
processor.Transform(sourceDoc, outputDoc.CreateWriter());
return outputDoc;

Other than that, the other slowdowns are probably in the SaxonWrapper itself and it's use of the older XmlDocument - rather than it's speedier cousin.

Problem

The following code works but is messy and slow. I am transforming an XDocument to another XDocument using XSLT2 with Saxon, adapted using SaxonWrapper: ``` public static XDocument HSRTransform(XDocument source) { System.Reflection.Assembly thisExe = System.Reflection.Assembly.GetExecutingAssembly(); System.IO.Stream xslfile = thisExe.GetManifestResourceStream("C2KDataTransform.Resources.hsr.xsl"); XmlDocument xslDoc = new XmlDocument(); xslDoc.Load(xslfile); XmlDocument sourceDoc = new XmlDocument(); sourceDoc.Load(source.CreateReader()); var sw = new StringWriter(); Xsl2Processor processor = new Xsl2Processor(); processor.Load(xslDoc); processor.Transform(sourceDoc, new XmlTextWriter(sw)); XDocument outputDoc = XDocument.Parse(sw.ToString()); return outputDoc; } ``` I realise that the slowness might actually be in the bits I have no control over but are there better ways to do all the switching between XDocument and XmlDocument and usage of writers?
