Main Documentation for grammar XmlGenEx.grm

The file test.exp contains a set of expressions that can be parsed and serialized. The resulting XML serialization of the example expression in that file can be seen in the file text.trace. The "pure" XML serialization of the expressions in that file can be seen in the file test.xml.

This declares the Java package for the parser generated from this grammar to be hlt.xml.

Include the ancillary java code contained in file ParserCode.grm for setting the generated parser's parameters and showing XML serialization.

This file contains ancillary code used by the Jacc grammar in XmlGenEx.grm, which illustrates how to use Jacc for XML generation from the syntax of a language - in this case, a language of simple expressions.

Declare the grammar start symbol to be EXP.

This declares this application XML's namespace to be http://www.hassan-ait-kaci.net/hex. This is just a fake, of course. (hex = hlt eamplexml).

Define the XML tree root element to be a hex:expressions.

Declare non-punctuation terminals NUMBER, IDENT, and VAR. NB: VAR is an identifier starting with a '?' (i.e., the '?' is part of it, not a separate token).

Declare operators from lowest to highest precedence.

Annotate terminal symbol VAR for XML serialization.

Annotate terminal symbol IDENT for XML serialization.

Annotate terminal symbol STRING for XML serialization.

Annotate terminal symbol NUMBER for XML serialization.

Annotate terminal symbol PLUS for XML serialization.

Annotate terminal symbol TIMES for XML serialization.

Annotate terminal symbol SMALLER for XML serialization.

Annotate terminal symbol GREATER for XML serialization.

Annotate terminal symbol EQUAL for XML serialization.

Annotate terminal symbol AND for XML serialization.

Annotate terminal symbol OR for XML serialization.
