search text for special characters

[sonic]

Hello,

Is it possible to search for special characters like a hashtag or something (eg #power) in a text and all other words with a hashtag, store them and use them later seperately...

so for example i have a text like this:

This is an example #text with several hashtags and i want the #words with the #hashtags filtered out so i can use them later for further #actions.

I can search for the '#' and any character behind it, but i don't know how to store and use it for later...

maybe somebody can help me or even give me some example code?

Thanks in advance!
