To develop a parser in Perl that will parse a perl script and generate Web GUI trees ( A DOM tree structure of the Perl code).
The input to this parser will be a perl file that has html tags embedded within the script.
The goal is to capture dependence relationships between perl code and the html code. There are 2 types of nodes here, A document node and a statement node. A document node represents the structure of an html statement while a statement node represents the embedded logic in the server page
