Your doubt stings. I realized that XML::LibXML will now do URI fetching itself so we can leave out dealing with the user agent stuff.
#!/usr/bin/env perl
use strict;
use warnings;
use URI::Amazon::APA;
use XML::LibXML;
use XML::LibXML::XPathContext;
my $key = $ENV{AWS_KEY} || "YOURKEYHERE";
my $secret = $ENV{AWS_SECRET} || "youforgottoputyourownsecretin";
my $asscociate = $ENV{AWS_ASSOC} || "this-isnt-it-20";
my $title = shift || die "You must provide a search string";
my $mode = shift || die "You must provide a mode, e.g., Books";
my $uri = URI::Amazon::APA->new("http://ecs.amazonaws.com/onca/xml");
$uri->query_form(
Service => "AWSECommerceService",
Operation => "ItemSearch",
ResponseGroup => "Large",
AssociateTag => $asscociate,
Title => $title,
SearchIndex => $mode,
);
$uri->sign( key => $key,
secret => $secret );
my $doc = XML::LibXML->load_xml( location => $uri );
my $xc = XML::LibXML::XPathContext->new($doc);
$xc->registerNs('amzn', $doc->getDocumentElement->namespaceURI);
if ( my @error = $xc->findnodes('//amzn:Error') )
{
die join("\n", map { $_->textContent } @error ), $/;
}
for my $item ( $xc->findnodes('//amzn:ItemAttributes/amzn:Title/text()
+') )
{
print $item->nodeValue, $/;
}
# print $doc->serialize(1);
Set-up ENV or add your info to the script and then–

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
