Create RSS Feed from Document Type in Umbraco using Razor

rss.feed.cshtml

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{umbraco.library.ChangeContentType("text/xml");

  var siteURL = "http://" + Request.Url.Host;
  var HomePage = CurrentPage.AncestorOrSelf(1);
  var RSSFeedPubDate = HomePage.Descendants("PressRelease").OrderBy("publishedDate desc").First();

}<?xml version="1.0" encoding="UTF-8"?>

@{

  foreach (var release in HomePage.Descendants("PressRelease").OrderBy("publishedDate desc").Take(10))
  {
    <item>
      <title>@release.Name</title>
      @Html.Raw("<link>")@[email protected](release.Url)@Html.Raw("</link>")
      <description>@release.Summary</description>
      <pubDate>@release.publishedDate.ToString("r")</pubDate>
      <guid>@[email protected](release.Url)</guid>
    </item>
  }
}

  </channel>
</rss>

Why not write this line more simple? :)

@Html.Raw("<link>")@[email protected](release.Url)@Html.Raw("</link>")

so instead this:

<link>@(siteURL + release.Url)</link>

or

<link>@(String.Format("{0}{1}", siteURL, release.Url))</link>
