    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 " +
