Using
XML dtd to validate an XML document
Consider
a case that you are going to produce an html output using an XSL and an
XML document. In such scenario, you might want the XML file to have the
elements in a particular order with the required number of elements and
the required number of attributes.

How
would you validate that the particular XML document is going to have so
many numbers of elements with the required attributes? This is where the
DTD and the Schema for the XML document comes.
You can use
an XML DTD to define how the XML elements are to be organized in an XML
document. This is necessary that you should have them in order so that
you can do the transformation properly.
So you have
to create a DTD for an XML document or create an XML document based on
a DTD. Whatever it is, the XML document has to be validated against a
DTD.
If you have
the proper IDE or the XML editor, they have an inbuilt tool that would
validate an XML document against a DTD. Use such tools to validate an
XML document. There are many free XML editors available in the market.
