Replace reoccurring string with increasing number

[1v4n0]

I got an epub of poetry where each verse is in its own specifically classed paragraph. Is there a quick way to add verse numbers before each paragraph? So to pass from

<p class="verse>Tu non altro che il canto avrai del figlio,</p>
<p class="verse>o materna mia terra. A noi prescrisse</p>
<p class="verse>il fato illacrimata sepoltura</p>

to

<p class="verse-number">1</p><p class="verse>Tu non altro che il canto avrai del figlio,
</p>
<p class="verse-number">2</p><p class="verse>o materna mia terra. A noi prescrisse</p>
<p class="verse-number">3</p><p class="verse>il fato illacrimata sepoltura</p>

Thanks.

You could use the Function mode in Calibre Editor or my simple Incremental IDs Sigil plugin.
(With my plugin you'd first have to add incremental ids and then use a regex to change the ids to tag values.)

BTW, if using epub3 books is an option for you, you could also use CSS with pseudo selectors to add line numbers. For details see this thread.

Ops, turns out I had already asked the same question three years ago

You can also use a XQuery script
