Description 

Author

This class can be used to extract data from text using regular expression patterns.

It takes an array of regular expressions that define the patterns to match and extract data.

An entry of the expressions array may be another array that defines patterns of repetitive sections that must be iterated to extract data from each of the repeated sections, like for instance HTML tables with sections of the rows of cell data.

The extracted data patterns is returned in associative arrays.

Regular expressions are often used to extract information from different types of text documents.

Sometimes it is necessary to extract information that appears with the same format in multiple sections of a document, like for instance, text that is presented in multiple rows of HTML table. Extracting data from this kind document may require the use of multiple types of regular expressions.

This class provides a solution to simplify the extraction of text from document with repetitive sections by iterating through a set of given regular expressions.

preg_magic ------------------- Version 1.0 Author: Shannon Wynter (http://fremnet.net/contact) Copyright Shannon Wynter & Fremnet.net Licence: GPL 2.0 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 Full Documentation: ------------------- You can generate full documentation by making sure you have phpDocumentor installed and running the document.sh file found in this directory License: ------------------- This library is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 2 of the License, or (at your option) any later version.
