Notification on new lines that match regex

[Rojetto]

What I'm trying to do is this: Using the CSS filter p.title I get a list of thread titles in a forum. Now I want to be notified when there is a new thread with a title that contains the keyword "A".

Here's what I tried:

1. Add the key phrase "A" to the "Trigger/wait for text" list. Result: I get notifications for every new thread, even ones that don't contain "A", as long as "A" is anywhere on the first page of threads.
2. Add an inverted regex /^(?!.*A).*$/ to the "Ignore text" list. Result: I still get notifications for every new thread, just most of the time they are empty:

https://example.com/ had a change.

3. Add the regex to the original filter, by using an XPath instead of a CSS selector: //p[contains(@class, 'title') and matches(., '.*A.*')]. Result: Doesn't work because XPath 2.0 isn't supported.

I feel like this should be very simple and I'm just not understanding something clearly. Would appreciate any explanations. Thanks!

Figure this out?

XPath2.0-3.1 is supported since 0.45.8. Try new version.

If it wouldn't be too troublesome, do you mind giving me more information about how to go about doing this? I haven't ever done anything with xpath.
