I was creating a blogger theme and I intend to have a card layout with the first image and a text-only summary (fixed characters followed by ...) in the post list.
I could get the first image of the post using data:post.firstImageUrl attribute. I would like to know how I can retrieve a specific string in the text of the post, for example a price, to place it above the image in the post list, can someone give me an idea of how I could do it?
