[feature] Filtering of notifications to show only specific text. For example include only text following "(into) "

[bananaabandit]

Version and OS
v0.48.03 running on Docker

Is your feature request related to a problem? Please describe.
I am trying to filter the notifications that are coming back from the website I am monitoring to only include the text following the "(into) " lines. I think a regex of (?<=((into)))(.+) would probably do it but as it doesn't exist on the page it is not being picked up on the "Extract text" section. However, it may be useful to use a regex for example to allow any level of filtering.

Describe the solution you'd like
I would like to be able to only show lines following the "(into) " see redacted example below. It would be ideal to filter out the "(changed) " section completely.

Describe the use-case and give concrete real-world examples

Additional context
In this case I am using a locally hosted ntfy set up to receive the notifications and passing in {{diff_added}}, I have tested with other options such as {{triggered_text}} but this didnt seem to do what I wanted. If there is something that exists already that will manage this please let me know :)

Its not super clear what you're asking, can you give an example of the text input and text output?

[dgtlmoon]

You want the text to be WITHOUT the " "(into) "" keyword? I cant understand what you're saying here

Sorry for the confusion, basically I am looking for a way to make succinct notifications. I have non techy relations who could use this for a number of tasks so when they get a notification through of what changed on the page it would be very helpful if they could see only the lines that are marked as (into) *.

If they see the lines that have (changed)* it will be a case of information overload.

I have had to amend the content unfortunately as gives away personal details but in the below example using the {{diff_added}} token I would expect lines through into ntfy including:

(changed) stuff that used to exist
(into) stuff that was added and I need to alert

I only want the lines beginning with (into) to be passed into my notifications (and if possible strip out the (into) characters but that isnt super important).
so all that would be left in the notification is:

stuff that was added and I need to alert

From scaped text here:

[dgtlmoon]

if the token {{diff_added}} (in the notification body) doesnt work, you can use this in the notification body

{% for line in diff_full.split('\n') if line.strip().startswith('(into)') %}
{{ line.strip()|replace('(into)', '')|strip() }}
{% endfor %}

let me know how it goes!

Thanks for getting back to me. Is that all done in Jinja2?
Sorry I totally missed that notifications could be changed in this way!
I have set this up now just waiting for a change to come through but will keep fingers crossed.

Thanks again!
