Comments: Currency converter interface


The Perl program given on this page is an example, for educational purposes only, of how to use the LWP::UserAgent and HTML::TreeBuilder modules to download a web page and extract information from it. Don't use this program to automatically extract data from, since the site strictly forbids this. The Perl program is just a simple example to get you started on how to fill in a web form and using the POST method to get the result back.

Read the rest of Currency converter interface.


I'm a learn by example kind of guy, and I searched the web pretty hard for a working example of how to use the post() method contained in the LWP::UserAgent module. I found lots of links to MANpages, but precious few examples of working code.

My search finally led me to your example; one that utilizes just the method I was looking to implement in my own code.

The way you presented the code allowed me to easily understand how the method worked and what I neeeded to do to use it for my own application.

I had my script up and running in about two minutes, after having spent a good 20 minutes beforehand struggling to understand.


By the way, my script extracts IEEE MAC address ownership information from the IEEE online database search page.

It seems like has changed their page layout this weekend and I can no longer use the script. Sadly, I'm not a Perl wiz and can't change the code myself.. An updated script would be most welcome!
