Here's a quick, untested, stab at it. Let's assume for this example that you are talking about <p> tags.
use HTML::TokeParser::Simple;
# assumes that $text is a scalar containing the actual HTML
my $p = HTML::TokeParser::Simple->new( \$text );
my $token;
do { $token = $p->get_token } until $token->is_start_tag('p');
my $new_text = $token->return_text;
do ( $token = $p->get_token ) {
my $temp = $token->return_text;
if ( $token->is_text ) {
$temp =~ s/\s+/ /g; # collapse whitespace
$temp =~ s/^\s//; # remove initial whitespace
$temp =~ s/\s$//; # remove trailing whitespace
}
$new_text .= $temp;
} until $token->is_end_tag('p');
$new_text .= $token->return_text;
This is a much cleaner method (and accurate) method of accomplishing this task than most regex solutions. I also happen to think that HTML::TokeParser::Simple is easier to use than many other HTML parsing modules. Of course, I may be biased as I wrote that module :)

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).
