You could, xylitol is basically a replacement for sugar, so if you don't have it you can replace it with white sugar. As for honey, I've never tried it but I'me sure you could try. Here's some info I found in regards to replacing sugar with honey:
Some minor adjustments may need to be made to a recipe when substituting honey for sugar:
1. Use equal amounts of honey for sugar up to one cup. Over one cup, replace each cup of sugar with 2/3 to 3/4 cup over honey depending upon the sweetness desired.
2. Lower the baking temperature 25 degrees and watch your time carefully since products with honey brown faster.
3. In recipes using more than one cup honey for sugar, it may be necessary to reduce liquids by 1/4 cup per cup of honey.
4. In baked goods, add 1/4 teaspoon of baking soda per cup of honey if baking soda is not already included in the recipe. This will reduce the acidity of the honey, as well as increase the volume of your product.
Moisten a measuring spoon or cup first with water, oil, or an egg before measuring the honey to prevent it from sticking to the measuring utensil.
