Data extraction.

[joe1986]

Hi there, new to Perl scripting, but ive been told its quite straight forward to pick up Anyway, im looking to write a small script that can be implemented in explorer and that can extract specific info off a page and export that info into a word document or excel file. Any pointers that could get me started?
Cheers
Joe

Extract info from a page on the internet? You don't typically use a browser for more than invoking a perl script, this would typically be a CGI script. This forum is an example of a CGI script written using PHP.

The server runs the code the browser just displays the formatted output from the script.

Read a good perl tutorial is my best pointer for now:

Beginning Perl - perl.org

worry about your specifc program requirements once you understand some basics.

Well..... heres a real world example of a very similar program, which controls word, and combines articles. Your mileage may vary. You may use all, parts of or none of this script.

I learned how to write the following program by looking at word controlling programs others had written.


#!c:\perl56\bin\perl
#
# Combine Articles using MS Word, and save them back to their original queue.

jon,

watch the post dates, this thread is several months old, the OP has posted this one question and never returned. But of course I only offer that as a suggestion, you are free to post replies in any thread you wish to.
