# yahoo_store_export_to_froogle.pl
#
# This is a Perl script to convert Yahoo! Stores XML feed into
#   Froogle data feed, and FTP the file to Froogle's server.
# Note: Many stores are automatically indexed by Froogle.
#
# REQUIREMENTS
#  A merchant agreement/ftp account with Froogle.
#  A Yahoo! store account with store export enabled.
#
# INSTRUCTIONS
#   This script requires no command line parameters and creates no output.
#   It places the Froogle data feed into the system temporary directory.
#   Parameters for the store and Froogle user account
#     must be entered in the section labeled "CUSTOM INFORMATION".
#   The script can be tested against a saved Yahoo store's xml file
#     and alternate FTP server by setting the "DEBUG VARIABLES".
#
# FEATURES
#  Fully automated. The Froogle data format is the simple format, not
#  extended format.  Entire store product library is processed.
#  Product code is taken as the Yahoo! store created abbreviation.
#  Image URLs and Section names are handled correctly.
#  All HTML tags are removed from product captions.
#  All tabs, carraige returns, and new lines are replaced with spaces.
#  Only products with a price are sent. Orderable flag is ignored.
#
# LIMITATIONS
#  No special handling for books, music, dvd, etc.
#  No support for quantity pricing or alternate currency.
#  No support for item options.
#  No support for partial uploads.
#
# EXAMPLE CRONTAB ('crontab -e' to edit the crontab)
#] # Send Yahoo Store data to Froogle daily at 6 am
#] 0 6 * * * /home/u/user/bin/yahoo_store_export_to_froogle.pl
