1st substitute/([A-Z][a-z][\W][\b])/<userinput>/;
The critical thing to remember about [...] character classes is that most regex metacharacters are not meta-special inside them. Thus, [.] (which you have used elsewhere) matches a single '.' (period) character and [\b] matches a single backspace control-character. So the pattern above might be described as:
-
[A-Z] A single upper-case character; followed by
-
[a-z] A single lower-case character; followed by
-
[\W] A single character that is anything not matching a \w 'word' character (\W is a class onto itself, so no enclosing square brackets are needed); followed by
-
[\b] A single backspace control character.
Is any of that what you really wanted?

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).
