Test, validate and match regular expressions
This regex captures content between two HTML class markers in a webpage. It matches text starting after 'row easyzoom-thumbnails' and ending before 'row expanded', using a non-greedy capture group to extract the content in between. With the 's' flag enabled, it can match across multiple lines. This pattern is commonly used for web scraping or HTML parsing to extract image thumbnail sections from pages using the EasyZoom JavaScript library.
