The following XPath will give exactly what you need:

"//span[text()='by ']/following-sibling::*[1]"

There are several points to be improved in your initial XPath:

1. //span[contains(text(),"by")] matches more than 16 relevant elements.
2. /following-sibling::* selects All the following siblings, of any tag name. But this selects all the following siblings, not only adjacent following siblings. To make this precise [1] index added.
