Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I want to get data from database by LWP::Simple::get. Regular one page only show up 20 items, My data total has 402 items. I use:
$mydata=get(' +cmd=search&term=RGS');
I only can get 20 items. The source code has options from 10,20,100,200,500. By hand if you choice SHOW=500, you can get 402 items. and then the URL is: But if you use above URL you will get nothing. The source code is:
&nbsp;Show:&nbsp;<select name="dispmax" onChange=" +edIndex=selectedIndex;"><option>5</option> <option>10</option> <option selected>20</option> <option>50</option> <option>100</option> <option>200</option> <option>500</option> </select>
What I can do about that? Please help! Thanks in advance!

    It should be pretty simple; note that the name attribute on the select is dispmax. So that's the value you need to send to the CGI that handles the form submission. Submitted variables, when using a GET request (as you are here) are separated by ampersands and take the form name=value (if that's confusing you, just look a the URLs you are already using for an example), so if you simply add &dispmax=500 to the URL that you are fetching, that ought to do it.

    P.S. This is more of an HTML question than a Perl question. You might want to try W3C Schools to learn more about HTML.


    If not P, what? Q maybe?
