Umbraco Sitemap - error CS1525: Invalid expression term '<'

Question

Umbraco newbie here. I'm following the documentation below to create a sitemap in Umbraco 8.1:

https://our.umbraco.com/documentation/tutorials/Creating-an-XML-Site-Map/

Everything seems fine but when I try to put live I get the error: error CS1525: Invalid expression term '<'

It seems to not be liking the HTML tags starting at URL - i've tried a few variants on Html.Raw() but it doesn't seem to work. Any help appreciated.

@{
    void RenderSiteMapUrlEntry(IPublishedContent node)
    {
        var changeFreq = node.Value("searchEngineChangeFrequency", fallback: Fallback.To(Fallback.Ancestors, Fallback.DefaultValue), defaultValue: "monthly");
        // with the relative priority, this is a per page setting only, so we're not using recursion, so we won't set Fallback.ToAncestors here and we'll default to 0.5 if no value is set
        var priority = node.HasValue("searchEngineRelativePriority") ? node.Value("searchEngineRelativePriority") : "0.5";

        <url>
            <loc>@node.Url(mode: UrlMode.Absolute)</loc>
            <lastmod>@(string.Format("{0:s}+00:00", node.UpdateDate))</lastmod>
            <changefreq>@changeFreq</changefreq>
            <priority>@priority</priority>
        </url>
    }

Answer 1

Resolved. I was using the code from Umbraco versions 9 & 10 - i'm using 8 so this worked:
