uk.ac.sheffield.jast.test.TestDTDScanner

public class TestDTDScanner
extends java.lang.Object

Demonstrates the use of DTDScanner to read tokens from Doctype grammars. Tests the ability to scan directly from a named DTD file; and to scan from an internal grammar subset that was stored as unparsed text in a Doctype node; and finally to access a DTD file referenced by the SYSTEM property of a Doctype node.

Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Demonstration program to read tokens with a DTDScanner, from Doctype grammars accessed in three different ways. Firstly, creates a DTDSCanner which opens the DTD file "Catalogue.dtd" directly, to scan its tokens. Secondly, reads the XML file "Catalogue.xml" into memory and extracts the Doctype from the root Document node, then creates a DTDScanner wrapping a StringReader, reading from the internal grammar subset, which is stored as a String in the Doctype node. Finally, creates a DTDScanner opening the file named by the PUBLIC or SYSTEM property of the Doctype node (stored as the value of the systemID).

Parameters:

args - are ignored.

Throws:

java.lang.Exception - if an error occurs.
