coverts each specific letter into uppercase
<p>Couldn't find an answer to this. Let's say I have a string:</p>

<pre><code>"\System\Classes\SomeClass"
</code></pre>

<p>And I want to convert this into:</p>

<pre><code>"\system\classes\someClass"
</code></pre>

<p>How can I do this - convert each "\X" into "\x"? Which regular expression should I use, and can I do this using regular expressions? (as far as I know they search only for the first occurrence of the searched pattern).</p>
