Unfortunately this would also match "TEST SENTENCE" (note the trailing whitespace).
The following test illustrates another method: #!/usr/bin/perl -w
my $data = <<'EOF';
This is a sentence. THIS \
IS A SENTENCE. This is \
a SEQUENCE OF UPPER WORDS and \
this is not.
EOF
while ( $data =~ m/(\b(?:[A-Z]+(?:\s+[A-Z]+)*)+\b)/g ) {
print "Upper Sentence: \"$1\"\n";
}
Outputs: Upper Sentence: "THIS IS A SENTENCE"
Upper Sentence: "SEQUENCE OF UPPER WORDS"

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).
