Beginquote without endquote and vice versa

[HHJT]

Hello,

How do I find quotes that have a beginquote but do not have an endquote, or vice versa?

For beginquote-missing paragraphs I use ^([^‘]+)[.,?!]$ which works fine.
But for endquote-missing paragraphs I use ‘([^’]+)$ and which works sort of; now it also omits paragraphs containing ‘I’d… and ‘he’s….

How do I include punctuation marks in my selection so it only finds paragraphs having a beginquote but not having an endquote preceded by an punctuation mark?

Language Tool extension is fairly good on finding unmatched quotes.

Thanx for replying.

Are talking about a language pack? I have it installed (Dutch). How do I customize it to find missing quotes?

I'm talking about an extension called Language Tool, from http://www.languagetool.org
