| 12 |  |  |  |  |  |  |  | 
| 13 |  |  |  |  |  |  | WWW::Scraper::ISBN::AmazonFR_Driver - Search driver for the (FR) Amazon online | 
| 14 |  |  |  |  |  |  | catalog. | 
| 15 |  |  |  |  |  |  |  | 
| 16 |  |  |  |  |  |  | =head1 SYNOPSIS | 
| 17 |  |  |  |  |  |  |  | 
| 18 |  |  |  |  |  |  | See parent class documentation (L) | 
| 19 |  |  |  |  |  |  |  | 
| 20 |  |  |  |  |  |  | =head1 DESCRIPTION | 
| 21 |  |  |  |  |  |  |  | 
| 22 |  |  |  |  |  |  | Searches for book information from the (FR) Amazon online catalog. | 
| 23 |  |  |  |  |  |  | This module is a mere paste and translation of | 
| 24 |  |  |  |  |  |  | L. The main (only?) difference is | 
| 25 |  |  |  |  |  |  | in the parsing of the result. Here it is done with simple regexp, whereas in | 
| 26 |  |  |  |  |  |  | L it was done using | 
| 27 |  |  |  |  |  |  | L. |
