RSS Feed multiple authors not importing

Hi,

I'm using Drupal 10. I have an RSS feed that is structured like this: https://pubmed.ncbi.nlm.nih.gov/rss/search/1P3PNIbOiNPcDPL2SYZaIbNfJAngz....

The authors are placed in the tags. I'm trying to import multiple authors into a plain text field that I'm allowing unlimited values. When using feeds it only imports the first author and not the rest.

I have tried using Feeds Tamper to explode/rewrite the data into an array and still doesn't work.

Any ideas on how I can accomplish importing multiple authors? Do I need to use a different type of field for my content type?
