Regex - Jesus wept...

JLius · 04-20-2016, 02:56 PM

Hi all

So I'm trying to change all

Code:

<p class="block_3">SOME TEXT</p>

to

Code:

<h1>SOME TEXT</h1>

So I use REGEX: Find

Code:

<p class="block_3">(\d+)</p>

and replace it with

Code:

<h1>/1</h1>

But calibre keeps saying 'no hits' when I press search. I put it on regex. What am I doing wrong here?

A couple of errors:

Find should be

Code:

<p class="block_3">(.+?)</p>

and Replace:

Code:

<h1>\1</h1>

\d+ means one or more digit-only characters. And wrong-direction slash in your Replace.

Thank you very much, that works!
I looked at this, but apparently I misunderstood: http://web.sigil.googlecode.com/git/...nced_find.html

Yeah, that only tells you about the Sigil S&R tool.

It doesn't really teach you anything about regex itself -- that was the next chapter in Sigil's User Guide.

Personally, my favorite regex tutorial is at http://www.regular-expressions.info
