Question

I’m writing a simple CMS.

I want to be able to load a View, having it included inside a master page, and then scan the HTML so that I can replace some custom tags (like {{blog}} with my own blog output) and then serve it up to the browser.

How can I get access to the HTML from the ViewResult in order to intercept it?

Answer 1

Sounds like you want to write an ActionFilterAttribute. This attribute has the following methods:

• OnActionExecuting – called just before the decorated action is executed
• OnActionExecuted – called after the action method is called, but before the ActionResult is rendered.
• OnResultExecuting – callled before the result is rendered
• OnResultExecuted – called after the result is rendered

There is an example here which returns either JSON or XML data depending on the ‘Content-type’ header: Create REST API using ASP.NET MVC that speaks both Json and plain Xml
