thank you for the snippet, I really appreciate it.
I found the need of handling arrays too: append them if found.
to combine {a:[1,2]} and {a:[3,4]} into {a:[1,2,3,4]} I had to edit the while loop in the middle:
while (my ($k,$v) = each %merged) {
my @hashes = grep { ref $_ eq 'HASH' } @$v;
#$merged{$k} = $v->[0] if (@$v == 1 && !ref $v->[0]);
# append text separated with \n\n, but do not duplicate identical values
$merged{$k} = join "\n\n", do { my %seen; grep {!$seen{$_}++} @$v} if (!ref $v->[0]);
# append arrays one to other
@{$merged{$k}} = map {@$_} @$v if (ref $v->[0] eq 'ARRAY');
$merged{$k} = mergehashes(@hashes) if @hashes;
}
I thought someone else will find this useful too.

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).
