Accessing the DocumentType of a Document

Published: Monday, 16 August 2004

Sample xml file:

<?xml version="1.0" ?>
<!DOCTYPE article PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" "">
  <title>Test article</title>
  <para>Test paragraph</para>

Assuming you have successfully parsed and loaded the xml file into a Document object, you can access the Document Type using the DocumentType object.

Document doc;
// assume that the doc has been created above.  
DocumentType doctype = doc.getDoctype();
System.out.println("doctype.getPublicId(): " + doctype.getPublicId());
System.out.println("doctype.getSystemId(): " + doctype.getSystemId());
System.out.println("doctype.getName(): " + doctype.getName());

The output of the above program would be:

doctype.getPublicId(): -//OASIS//DTD DocBook XML V4.2//EN
doctype.getName(): article
