Howto: automated data submission to a form page

Posted on 2004-03-23

Is there a programming method I can use to go to a form page on the web (via a Perl script), enter some value like a zip code into a form field on that page (again via the script that is picking the inputs out of a text file, say), then when the result page is returned, retrieve it and parse it for data?  I know Perl and C, so the problem areas for me are (a) automatically submitting a piece of information to the form page (like zip code), and (b) retrieving the html of the result page so I can scrape it.  Thanks, hope that's clear.

You would probably want to use the Perl LWP::Simple module.

Assuming the form uses a GET request (the results page has page.cgi?formvalue=data, or something like that), you can simply retrieve the page using the LWP module.  Example code is below:

#!/usr/bin/perl
use LWP::Simple;
my $html = get("http://website/page.cgi?zipcode=12345"); #download the site

#$html now contains the HTML code for the page.  You can use a regular expression to parse it.

Both of you helped me, thanks a lot.  The page I care about today uses POST, so Tintin's Perl reference is actually more helpful, but rkosai's solution is clear, and can be helpful in the future.  I will be doing more of this type of web programming soon. Thanks a lot.

I am brand new to experts-exchange, and I CANNOT bookmark my questions!!  When I click "bookmark" at top left, I get nothing, with a note telling me how to click "add", etc, which I have done over and over.  I submitted the prob. to the EE bug page, but got no response yet.

Thanks again.

As you'll soon discover the LWP bundle is great for doing all sorts of web type activities.  

Don't forget to read through the LWP tutorial

Not sure why you are having a problem with the bookmarks.  What browser are you using?
