9.5: How do I extract URLs?

You can easily extract all sorts of URLs from HTML with
"HTML::SimpleLinkExtor" which handles anchors, images, objects, frames,
and many other tags that can contain a URL. If you need anything more
complex, you can create your own subclass of "HTML::LinkExtor" or
"HTML::Parser". You might even use "HTML::SimpleLinkExtor" as an example
for something specifically suited to your needs.

You can use URI::Find to extract URLs from an arbitrary text document.

Less complete solutions involving regular expressions can save you a lot
of processing time if you know that the input is simple. One solution
from Tom Christiansen runs 100 times faster than most module based
approaches but only extracts URLs from anchors where the first attribute
is HREF and there are no other attributes.

Hi. I don't know anything about proxies or networking yet I've been
tasked with protecting some content on a media server and I'm guessing
a proxy is the way to go. I'm playing around with HTTP::Proxy just to
get a feel for things. All of the examples and discussions seem geared
to a proxy which sits on a user's computer while what I want is to put
the proxy on an intermediate server between the user and the media
server. So just to test I set up a bare bones HTTP::Proxy script on
one of our web servers. It runs and I can connect to it but I don't
know where to start trying to get it to do more:

use strict;
use warnings;
use HTTP::Proxy;

my $proxy = new HTTP::Proxy (port => 8100, host => undef);
$proxy->start;

When I connect http://www.myserver.edu:8100 I get the message:
"Scheme is not supported by this proxy."

How can I do something simple like pipe the google homepage to my
browser (not redirect!)?

8.47: How do I keep my own module/library directory?

When you build modules, tell Perl where to install the modules.

For "Makefile.PL"-based distributions, use the PREFIX and LIB options
when generating Makefiles:

perl Makefile.PL PREFIX=/mydir/perl LIB=/mydir/perl/lib

You can set this in your CPAN.pm configuration so modules automatically
install in your private library directory when you use the CPAN.pm
shell:

%% cpan

For "Build.PL"-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

Hello all,

I'm just starting to get into perl, so please forgive me if I'm asking
something obvious.

I'm using the unpack function to parse through a fixed length file.
It's working well, but there's lots and lots of fields, and I'd like
to make the code more readable.

What I have now is this:

$LOGFILE = "text.log";
open(LOGFILE) or die("Could not open log file.");

# Define the record format for unpack function
$BaseBSPFileTemplate =
"A3" # RecordType Field 0
."A8" # SequenceNumber Field 1
."A2" # RecordTypeSuffix Field 2
."A6" # CreateDate Field 3
."A6" # TransactionNumber Field 4
."A15" # DataNumber Field 5
."A98" # UpdateDate Field 6
;

8.45: How do I install a module from CPAN?

The easiest way is to have a module also named CPAN do it for you. This
module comes with perl version 5.004 and later.

$ perl -MCPAN -e shell

cpan shell -- CPAN exploration and modules installation (v1.59_54)
ReadLine support enabled

To manually install the CPAN module, or any well-behaved CPAN module for
that matter, follow these steps:

1 Unpack the source into a temporary area.

2
perl Makefile.PL

8.41: How do I use an SQL database?

The DBI module provides an abstract interface to most database servers
and types, including Oracle, DB2, Sybase, mysql, Postgresql, ODBC, and
flat files. The DBI module accesses each database type through a
database driver, or DBD. You can see a complete list of available
drivers on CPAN: http://www.cpan.org/modules/by-module/DBD/ . You can
read more about DBI on http://dbi.perl.org .

Other modules provide more specific access: Win32::ODBC, Alzabo, iodbc,
and others found on CPAN Search: http://search.cpan.org .
