So for me and many others it was that time of year to set your clocks back in October. This time it was Fall back. Which reminded me. I recently discovered a method that lets me turn off fallback language when I need to in code. There are certain thing I wanted language fallback on and certain things I didn’t want it on for. Sitemap/Alternative Links was something that I only wanted to show links that have language versions for. Using this switcher I only get the items that we have a version a created a language for.

using (new LanguageFallbackItemSwitcher(false))
{
     var itemChildren = Sitecore.Context.Item.Children;

     foreach (Item childItem in itemChildren)
     {
          var urlOpt = new ItemUrlBuilderOptions
          {
               LanguageEmbedding = LanguageEmbedding.Always
          };

          foreach (var lang in item.Languages)
          {
               var langItem = childItem.Database.GetItem(childItem.ID, lang);

//If the switcher is set to true you would get all language versions of an item including fallback
//In this case we just want versions that are created and not using fallback.
      if (langItem.Versions.Count <= 0)
      {
          continue;
      }

urlOptions.Language = lang;
var itemUrl = LinkManager.GetItemUrl(langItem, urlOpt);
      links.Add(new KeyValuePair<string, string>(lang.Name, SiteHelper.EnsureScheme(itemUrl)));
                    }
                }
}

Simple yet effective.
