It seems that Web::Scraper uses HTML::TreeBuilder::XPath, and HTML::TreeBuilder has an no_space_compacting option that is disabled by default, causing that module to do s/[\n\r\f\t ]+/ /g by default. At the moment I don't see a way to set arbitrary options on the parser via Web::Scraper, this is probably worth opening an issue for.
Two workarounds I see at the moment: replacing Web::Scraper with Web::Scraper::LibXML works for me:
use warnings;
use strict;
use Data::Dump;
use Web::Scraper::LibXML;
my $scraper = scraper {
process '//p[contains(@class, "myClass")]',
'paragraph' => 'TEXT';
};
dd $scraper->scrape(\<<'END_HTML');
<p class="myClass">Blah
Blah
Blah
</p>
END_HTML
__END__
{ paragraph => "Blah\n\nBlah\n\nBlah\n" }
Or, monkey-patching Web::Scraper::build_tree:
*Web::Scraper::build_tree = sub {
my($self, $html) = @_;
my $t = HTML::TreeBuilder::XPath->new;
$t->store_comments(1) if ($t->can('store_comments'));
$t->no_space_compacting(1);
$t->ignore_unknown(0);
$t->parse($html);
$t->eof;
$t;
};

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).
