preg_magic

Class/Function to assist with parsing great piles of garbage (ie: HTML) into nice
hashes/associative arrays with a few regular expressions.

Basic Synapsis:
-------------------

preg_magic($Fields, $Target)

$Fields is an associative array that contains the structure you
expect to extract from the file.

It is very important to understand that you must supply the fields
in the order that you expect them to be matched.

There are currently two types of fields
 - simple
 - table

A simple field is simply defined as 'name' => 'expression to match'

A table field is a whole lot more complicated but it's also very
flexable, and is defined as follows:

 '@table'       => true,
 '@table_start' => 'the expression to match at the start of the table',
 '@table_end'   => 'the expression to match at the end of the table',
 '@table_fields => array(of more fields),

Both @table_start and @table_end will be ignored if this is the
root element of the array.

So an example structure might look like the example file
example/fields_example.php - This example shows two simple fields,
and a table

The structure can be recursive, ie, you can have more table and
simple fields beneith the table field

A full example can be found in example/full_example.php
