with the DTD files. Code completion, syntax coloring, and contextual
help are some of the features that you can expect in such products.
With the code completion feature it is not necessary to remember all
the syntax and the values of the attributes.
XMLSpy
is one product that has been in the market for a long time and the features
of this product are many. This product can be used as a DTD tool with
ease.
The interface
is user friendly. But this is a commercial product and you have to buy

be used as a DTD tool. Products like Stylus Studio, Exchanger, and Cooktop
are also used for this purpose. There are many such products in the
market.
