I think what I need then is a regex expression that will let me find:
<p class="para c2">“Ignore whatever characters may be in this paragraph.”</p>
and replace it with:
<p class="para"><span class="italic">“Ignore whatever characters may be in this paragraph.”</span></p>
Any suggestions? I'm OK with extremely basic regex but I get lost when trying to build larger expressions that will look for something specific with some random text in the middle and then allow me to replace the exact portion of random text as is.
