I just submitted a patch to the mvc contrib project that contains the xslt view engine I wrote for Xero without any of the dependencies from our own libraries or commercial components.
The bulk of the work is done in a class called XmlResponseBuilder which builds the xml document that is going to be transformed by the xsl stylesheet. Almost all the rest of the code is there just to build up this document.
The implementation of IView and IViewFactory were the easy bits :)
To use the View engine you need to take the following steps:
- Get the MVC Contrib project from google code
repository url: http://mvccontrib.googlecode.com/svn/trunk/
- If the patch hasn’t been applied yet you can download it from: http://www.codeplex.com/Project/Download/FileDownload.aspx?ProjectName=MVCContrib&DownloadId;=23748
After downloading the patch you can apply it to the downloaded mvc contrib project.
- I use a base controller to ensure that the correct data is passed to the view factory. This is the base controller class:
public abstract class XeroControllerBase : Controller
{
private readonly XsltViewData vData = new XsltViewData();
protected IHttpSessionState Session
{
get { return ControllerContext.HttpContext.Session; }
}
public XeroControllerBase()
{
ViewFactory = new XsltViewFactory();
}

}
