Hi there,

I'm trying to code a cookbook, I've done the XML for a recipe but am really struggling to get the correct DTD valid.

Any help would be MASSIVELY appreciated for a noob. Eventually the DTD and XML will have two recipes, hence why there is mention of recipetwo in the DTD.

I keep facing errors such as document element does not allow element 'ingredient' here.
Also error element "prep_ingredient" undefined.

Like I said, any help would be appreciated for a beginner. Thanks!!

This is the DTD so far followed by the XML
<?xml version="1.0" encoding="UTF-8"?>
