+ <h3 class="section">Regular Expressions</h3>   <p>A <em>regular expression</em>, or <em>regexp</em> for short, is a pattern that denotes a (possibly infinite) set of strings. Searching for matches for a regexp is a very powerful operation. This section explains how to write regexps; the following section says how to search for them. </p>   <p>For interactive development of regular expressions, you can use the <kbd>M-x re-builder</kbd> command. It provides a convenient interface for creating regular expressions, by giving immediate visual feedback in a separate buffer. As you edit the regexp, all its matches in the target buffer are highlighted. Each parenthesized sub-expression of the regexp is shown in a distinct face, which makes it easier to verify even very complex regexps. </p> <p>Note that by default Emacs search ignores case (see <a href="searching-and-case">Searching and Case</a>). To enable case-sensitive regexp search and match, bind <code>case-fold-search</code> to <code>nil</code> around the code you want to be case-sensitive. </p> <table class="menu" border="0" cellspacing="0"> <tr>
