DTD to java

Question

i need to write a model class for a dtd file, that is, read a dtd and model it into fields in,say, a java object. Is there an easy way to do it?

Hi,
you might want to check JAXB ( [https://jaxb.dev.java.net/|https://jaxb.dev.java.net/] ), which supports XML schema, but also DTD. It is used to create Java classes from an XML schema or DTD, which also contain code to marshal or unmarshal an XML document to Java classes or vice versa.
JAXB (package javax.xml.bind) ist part of Java SE 6.0. In prior versions, it was shipped separately or as part of the web service tools.

PS: after reading your post a second time I see, that you do not want to create classes out of a DTD, but objects which contain a description of the classes! That's not the intention of JAXB.
However the developers of JAXB had to do the same when they wrote the JAXB DTD compiler. So perhaps you get some ideas if you look for the source code of the reference implementation of the JAXB compiler.
