Test, validate and match regular expressions
Matches a .gif image URL followed by query string parameters (key=value pairs separated by &) and a trailing double quote. Intended for removing query parameters from GIF image URLs embedded in HTML attributes—use it with a replacement like `.gif"` to strip tracking or cache-busting parameters while keeping the closing quote intact. The gm flags allow processing multiple URLs across all lines.
