I fucking hate regex...The most complicated thing I have ever been able to do is replace stuff in a series of numbers.
"[^"]*"
something like changing everything to <p>
<div id="1"></div>
<div id="2"></div>
<div id="3"></div>
<div id="4"></div>
Find
<div id="[^"]*"></div>
and replace with
<p id="[^"]*"></p>
results
<p id="1"></p>
<p id="2"></p>
<p id="3"></p>
<p id="4"></p>
