Hi

I have a book with over 900 notes. After OCR and tweaking with Sigil FootnoteLinker plugin, these notes are now numbered from 1 to 900 and links are OK.

However, the paper book lists notes by chapter. So, without touching the links, I need to change the note numbers, chapter by chapter.

<h3 id="toc1">first</h3>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn1">
<span class="notesymbol"><a class="note" href="chapter10.xhtml#bodyftn1">1</a> text-one.</span>
  </aside></p>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn2">
<span class="notesymbol"><a class="note" href="chapter10.xhtml#bodyftn2">2</a> text-two</span>
  </aside></p>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn3">
<span class="notesymbol"><a class="note" href="chapter10.xhtml#bodyftn3">3</a> text-three</span>
  </aside></p>

.../...
  
  <h3 id="toc2">second</h3>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn10">
<span class="notesymbol"><a class="note" href="chapter12.xhtml#bodyftn10">10</a> text-ten</span>
  </aside></p>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn11">
<span class="notesymbol"><a class="note" href="chapter12.xhtml#bodyftn11">11</a> text-eleven</span>
  </aside></p>

  <p class="note"><aside class="ntb" epub:type="footnote" id="ftn12">
<span class="notesymbol"><a class="note" href="chapter12.xhtml#bodyftn12">12</a> text-twelve</span>
  </aside></p>

Here for example you can see three numbers I'd like to change by selecting the items under the second h3 title and performing .. something.

10 would become 1
11 would become 2
12 would become 3 and so on till the end of selected items.

Does somebody knows a way to do it?

I hope I have been clear...
