So I've now run into this problem twice. Hopefully, the reg-ex wizards among you will have a head-slappingly simple solution to my problem.

First Case
Every new paragraph is formatted as:

Code:

<p class="calibre2"><span class="none">A Bunch of Text</span></p>

I want to change the "p class" to "calibre5" for Chapter headings only, which are currently formatted like this (1., 2., 3., ..., 21., 22., etc):

Code:

<p class="calibre2"><span class="none">1.</span></p>

Finding all the instances with reg-ex is easy enough by searching for:

Code:

<p class="calibre2"><span class="none">[0-9]+\.</span></p>

But that's as far as I can get. Replacing the above with:

Code:

<p class="calibre5"><span class="none">[0-9]+\.</span></p>

changes the number to "[0-9]+\."!

Second Case
In another book, there are random paragraph breaks mid-sentence.
My solution to that would be to find all the new paragraphs that begin with a lower-case letter, and replace all the code between it and the previous paragraph. Again, finding the instances via reg-ex proved pretty intuitive:

Code:

</p>[\s]+<p class="calibre2">[a-z]

But again, i just can't figure out how to alter the code (in this case replacing it with a blank space) without altering the first letter of the first word in that paragraph.

Looking over what I've written, I am humbled by how utterly inarticulate this all sounds, but if someone understands my gibberish, I'd be most grateful for any light you could shine on my problem.
