DTDParser

As a software review, one can observe that there are limited options when it comes to DTD parsers for Java. This could be attributed to the fact that DTD does not qualify as valid XML. However, until XML Schema gains wider acceptance, DTDParser can serve as a useful tool for parsing DTDs.

Using this DTD parser is a straightforward process. Firstly, you need to create a java.io.Reader to read the DTD. Then, you can create an instance of com.wutka.dtd.DTDParser and pass the Reader to the constructor. Finally, you call the parse method which returns a DTD object - similar to the Document object in the DOM model.

Overall, while the scarcity of DTD parsers for Java is a challenge, the DTDParser offers a reliable option for parsing DTDs. Its simple implementation and ability to return a DTD object make it a valuable tool for developers working with DTDs.
