What is the best way to return XML from a controller's action in ASP.NET MVC?
I'm able to return JSON and partial views (html) as a valid ActionResult, but how would one return an XML string?
-
Use the XmlResult from MvcContrib on Codeplex. Also this seems to be a duplicate question.MotoWilliams– MotoWilliams2009-05-18 19:10:18 +00:00Commented May 18, 2009 at 19:10

You could use return this.Content(xmlString, "text/xml"); to return a built XML string from an action.

If you're working with Linq to XML, creating a string form of the document is wasteful -- it's better to work with streams.
For JSON/XML I have written an XML/JSON Action Filter that makes it very easy to tackle without handling special cases in your action handler (which is what you seem to be doing).

For anyone reading this post - definately check out his filter... it works well. +1 to aleemb for sharing!
Another way to do this is by using XDocument:
using System.Xml.Linq;
public XDocument ExportXml()
{
Response.AddHeader("Content-Type", "text/xml");
return XDocument.Parse("<xml>...");
}

Some experimentation in MVC 4 (and possibly earlier versions) suggests that the MIME type returned here is
text/html.If you're building the XML using Linq-to-XML then check out my answer here. It allows you to write code like this:
public ActionResult MyXmlAction()
{
var xml = new XDocument(
new XElement("root",
new XAttribute("version", "2.0"),
new XElement("child", "Hello World!")));
return new XmlActionResult(xml);
}
