Regex Editor & Tester

This regex matches a specific custom field block (`wpcf-lookbook-front-image`) within a WordPress XML export file. It uses capturing groups and backreferences to accurately match the opening and closing `<wp:postmeta>`, `<wp:meta_key>`, and `<wp:meta_value>` tags while handling surrounding whitespace. It is highly effective for parsing WXR files to extract specific post metadata or migrating custom fields.
