Sitemap rendering issue
Hello,

I'm facing an issue with the rendered code in sitemap. I need to render this code : <xhtml:link rel="alternate"... But the :link is creating plain text rather than the proper xml display.
```
@helper RenderHrefLangEntries(IPublishedContent node)
{
    if (node.Cultures != null)
    {
        foreach (var culture in node.Cultures)
        {
            var cultureKey = culture.Key;
            var cultureUrl = EnsureUrlStartsWithDomain(node.Url(cultureKey, UrlMode.Absolute));
            @Html.Raw($"<xhtml:link rel=\"alternate\" hreflang=\"{cultureKey}\" href=\"{cultureUrl}\" />")
        }
    }
}
```
I understand that the issue is related to the colon character. Is there an alternative way to display it correctly?

Thanks

Based on the Umbraco official document I made this Service. I hope it will help you:

public class XmlSiteMapService : IXmlSiteMapService
{
    public string RenderXmlSiteMap(IPublishedContent node, int? maxSiteMapDepth, string? excludedDocumentTypeList)
    {
        var maxSiteMapDepthValue = maxSiteMapDepth.HasValue ? maxSiteMapDepth.Value : int.MaxValue;
        var excludedDocumentTypes = (!string.IsNullOrEmpty(excludedDocumentTypeList)) ? excludedDocumentTypeList.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries).Select(p => p.Trim()).ToArray() : new string[] { };
        var xmpMapForHomePage = RenderSiteMapUrlEntry(node);
        var xmlMapForChildren = RenderSiteMapUrlEntriesForChildren(node, maxSiteMapDepthValue, excludedDocumentTypes);
        var retVal = new StringBuilder();
        retVal.AppendLine("<urlset " +
            "xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\" " +
            "xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" " +
            "xsi:schemalocation=\"http://www.google.com/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd\" " +
            "xmlns:image=\"http://www.google.com/schemas/sitemap-image/1.1\">");
        retVal.AppendLine(xmpMapForHomePage);
        retVal.AppendLine(xmlMapForChildren);
        retVal.AppendLine("</urlset>");
        return retVal.ToString();
    }
    private string RenderSiteMapUrlEntry(IPublishedContent node)
    {
        var changeFreq = node.Value("searchEngineChangeFrequency", fallback: Fallback.To(Fallback.Ancestors, Fallback.DefaultValue), defaultValue: "monthly");
        if (changeFreq == null)
        {
            return string.Empty;
        }
        var priority = node.HasValue("searchEngineRelativePriority") ? node.Value<string>("searchEngineRelativePriority") : "0.5";
        var xmlContent = $$"""
                            <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>
                            """;
        return xmlContent;
    }
    private string RenderSiteMapUrlEntriesForChildren(IPublishedContent parentPage, int maxSiteMapDepth, string[] excludedDocumentTypes)
    {
        var retVal = new StringBuilder();
        foreach (var page in parentPage.Descendants().Where(x =>
            !excludedDocumentTypes.Contains(x.ContentType.Alias) &&
            x.HasValue("hideFromXmlSiteMap") &&
            !x.Value<bool>("hideFromXmlSiteMap")))
        {
            retVal.AppendLine(RenderSiteMapUrlEntry(page));
            if (page.Level < maxSiteMapDepth && page.Children.Any(x => !x.Value<bool>("hideFromXmlSiteMap")))
            {
                retVal.AppendLine(RenderSiteMapUrlEntriesForChildren(page, maxSiteMapDepth, excludedDocumentTypes));
            }
        }
        return retVal.ToString();
    }
}
