fixing up chapter numbers

[cybmole]

i often find books that have chapter starts as numbers in bold, and i need them to be in H1 or H2 tags in order to calibre to detect and build TOC.

is there any sigil - regex find replace command that could pick out lines like

<p class="calibre8"><span class="calibre3 bold">7</span></p>

and replace with

  <h2>7</h2>

for all instances of 1 or 2 digit numbers ?

the numbering of the calibre tags varies from book to book but I'm happy to set those up once per book

the construction p class="calibre8"><span class="calibre3 bold" does not occur outside of chapter headers so that can be replaced with h2, but I then have to also replace the end of string p with h2 & that is what has me beat.

Find:
<p class="calibre8"><span class="calibre3 bold">([0-9])</span></p>

Replace:
<h2>\1</h2>

This will do chapters 1-9.

For Chapters 10+
Find:
<p class="calibre8"><span class="calibre3 bold">([0-9][0-9])</span></p>

Replace:
<h2>\1</h2>

or
<p class="calibre8"><span class="calibre3 bold">(\d+)</span></p>
for any number of digits in a row.

Hey... thanks, one less search is good

thanks guys - I am slowly getting the hang of regex find+replace.

this is useful for books which have chapters within sections/parts as calibre's structure detect only puts the main sections into TOC ( unless chapters numbers are converted to h2 tags as per this thread)
