Replace formatting with tags; ALMOST there, but need help

[CompleteNewb]

I've gotten surprisingly far with replacing formatting in a Word document
with html tags, but one thing is not working.

Anywhere I have two new paragraphs, some text, then a <br> (I already did
one pass putting the br's where I want them), I want to have the new
paragraphs and:

<p class="someclass">Any text here</p><br>

So, for example:

blah blah blah¶
¶
Blah Blah Blah<br>
blah blah blah blah blah blah blah blah

Would become this:

blah blah blah¶
¶
<p class="someclass">Blah Blah Blah</p><br>
blah blah blah blah blah blah blah blah

Now, I've tried using the replace like this:

Find: ^13^13*<br> (I'm using wildcards, so have to use the ^13 instead of
^p)

but it finds nothing. It WILL find the ^13^13, but if I use the * or
anything after that, it says there are no results. I made sure there are no
extra line breaks, carriage returns, etc. after the second ¶ (at least, I
think I did; Word doesn't show any marks after the second ¶, and I tried
looking for ^13^13^l as well, and it says there are none of those).

Can anyone help me figure out why I can't do this?

Thanks for any help, and I appreciate your time.
