I have user entering chunk of text in a textarea. For the most part this will just be typing. On display, I want to convert two newlines into two BR tags, to preserve the formating from the textarea. So this works fine:
my $text = get_text_from_db(..);
$text =~ s|\n|<br />|sg;
But these don't (can someone tell me why?):
$text =~ s|\n\n|<br /><br />|sg;
$text =~ s|\n{2}|<br /><br />|sg;
In the end I want to convert any two newlines to two BR tags, but only if they are not followed by another html tag. So I am hoping for something like:
$text =~ s|\n{2}(^<)|<br /><br />$1|sg;

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
