How to create a DTD in XML

You can easily create dtd's if you are using a good xml or dtd editor. Some of the leading products used for xml editing also have the feature of creating dtd's from the scratch.

The code completion features available in such editors would come in handy to you to create dtd. If you already have an xml document that does not have a dtd corresponding to it, then you can generate a dtd for that document using the xml editors like XMLSpy, Xselerator, and Cooktop etc. based on the xml documents structure the editor will generate a dtd for you. It is just that simple!

The other option is to create your own dtd file from the scratch for this you should know the grammar of dtd. The file you create should have an extension '.dtd'. if you are using a good dtd editor then you can always find help in writing the syntax of dtd like, choice, sequence, optional and others.

Buttons to add the modifiers to the document are available and you need not remember the syntax of all. This is the greatest advantage of using a good dtd or xml editor. Try creating one using them!
