This program is a parser that abstract a data structure from a given Entrez Gene record, and users of the parser can decide what to do/extract from the data structure.

Perl Entrez Gene Parser project provides Perl parsers for NCBI's Entrez Gene based on regular expression, Parse::RecDescent, Parse::Yapp and Perl-byacc. Some can parse human genome annotations in minutes. Documentation and user guides are provided.

For this purpose, we consider several automatic parser generators as well as the venerable Perl5 regular expressions. The tools we considered are: Parse::RecDescent, Parse::Yapp, Perl-byacc, Text::Balanced and Regex.
