9 version 2.07
10
12 Plenty of people have learned WWW::Mechanize, and now, you can too!
13 Following are user-supplied samples of WWW::Mechanize in action. If
15 you have samples you'd like to contribute, please send 'em to
16 "<andy@petdance.com>".
17 You can also look at the t/*.t files in the distribution.
19 Please note that these examples are not intended to do any specific
21 task. For all I know, they're no longer functional because the sites
22 they hit have changed. They're here to give examples of how people
23 have used WWW::Mechanize.
24 Note that the examples are in reverse order of my having received them,
26 so the freshest examples are always at the top.
27 Starbucks Density Calculator, by Nat Torkington
29 Here's a pair of programs from Nat Torkington, editor for O'Reilly
30 Media and co-author of the Perl Cookbook.
31 Rael [Dornfest] discovered that you can easily find out how many
33 Starbucks there are in an area by searching for "Starbucks". So I
34 wrote a silly scraper for some old census data and came up with
35 some Starbucks density figures. There's no meaning to these
36 numbers thanks to errors from using old census data coupled with
37 false positives in Yahoo search (e.g., "Dodie Starbuck-Your Style
38 Desgn" in Portland OR). But it was fun to waste a night on.
39 Here are the top twenty cities in descending order of population,
41 with the amount of territory each Starbucks has. E.g., A New York
42 NY Starbucks covers 1.7 square miles of ground.
43 New York, NY 1.7
45 Los Angeles, CA 1.2
46 Chicago, IL 1.0
47 Houston, TX 4.6
48 Philadelphia, PA 6.8
49 San Diego, CA 2.7
50 Detroit, MI 19.9
51 Dallas, TX 2.7
52 Phoenix, AZ 4.1
53 San Antonio, TX 12.3
54 San Jose, CA 1.1
55 Baltimore, MD 3.9
56 Indianapolis, IN 12.1
57 San Francisco, CA 0.5
58 Jacksonville, FL 39.9
59 Columbus, OH 7.3
60 Milwaukee, WI 5.1
61 Memphis, TN 15.1
62 Washington, DC 1.4
63 Boston, MA 0.5

167 pb-upload, by John Beppu
169 This program takes filenames of images from the command line and
170 uploads them to a www.photobucket.com folder. John Beppu, the author,
171 says:
172 I had 92 pictures I wanted to upload, and doing it through a
174 browser would've been torture. But thanks to mech, all I had to do
175 was `./pb.upload *.jpg` and watch it do its thing. It felt good.
176 If I had more time, I'd implement WWW::Photobucket on top of
177 WWW::Mechanize.

300 quotes.pl, by Andy Lester
302 This was a program that was going to get a hack in Spidering Hacks, but
303 got cut at the last minute, probably because it's against IMDB's TOS to
304 scrape from it. I present it here as an example, not a suggestion that
305 you break their TOS.
306 Last I checked, it didn't work because their HTML didn't match, but
308 it's still good as sample code.
