Because your regex is anchored to the start and end of the string, so it'll only find a tag that's on a line by itself:
if (/^\{(.*)\}$/) {
$tag = $1;
print "The tag is $tag\n";
}
Your {TTL} and {LINE} tags are in the middle of the line, so they won't get picked up by the regex.
You could try something like this instead:
while (/\{(.*?)\}/g) {
$tag = $1;
print "The tag is $tag\n";
}
Output:
The tag is SOURCETAG
The tag is DATE
The tag is EDITION
The tag is HEADLINE
The tag is SOURCE
The tag is LINE
The tag is TTL

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).
