Regex to remove certain strings fromn rss

[robotfx]

I"d like to know if itis possible to remove certain strings from rss feeds. I am trying to use huggin on heroku, to combine a few feeds into one, like yahoopipes used to. That works fine, but I do need some things removed, like for example img alts, img captions etc. If this is possible, I haven't been able to find info about it. Please help

There most probably is a way to do it, pipe the Events to a ManualEventAgent and use one of the liquid regular expression filters.

Sorry, it's a little above my head. My diagram looks like below, but I have no idea what to enter the ManualEventsAgent.

The RSS is a collection of my favorite feeds, the Output if simply sorting them by date and displaying them properly.
Ideally, I'd like the links removed, and therefore looking for a regex (probably) to delete everything from. and including
<a ... /a>
Can you please post here what the content of the ManualEventAgent should be in order to accomplish this?
Thank you.

Something like this (no need to adjust the regular expression based on the data you are receiving:

{
  "instructions": {
    "some_other_field": "{{ content | regex_replace: \"\\x22(.*?)\\x22\", \"\" }}"
  },
  "matchers": [],
  "mode": "merge"
}
