Debuggex is an online Regex testing tool that allows visualization of Regex match algorithms. The visualization feature is good both for the learners who do some Regex exploration and for the experienced users who might want to track the Regex match forward or back. It is also useful for an instant Regex pattern match by highlighting, thus eliminating the need for pressing any buttons to run Regex patterns. This tool is one of a dozen online Regex testers.

Both form submission via POST, HTTP 302 Redirect outwork and cookie storing performance will be checked for each scraper.
Since we’ve reviewed the Web Scraper Shortcode, we consider now some issues with this Word Press plugin. It is the Word Press plugin for extracting a web page or a part of it and inserting it into a custom Word Press driven page.
