How to use regex on Text extracting element?

I read this: Text selector | Web Scraper Documentation

But I can’t find how to add a Regex to an extracted text. Expresión is on the htmlInner text and needs to be like this: ((\d+)\D?)+

I already tried to put it on the exporting file but it says that JSON format is invalid, I don’t know if this is a bug because I only put the Regex between this “”.

Any help is appreciated.

The regex feature was unfortunately removeed from the GUI but it can still be added manually. It needs to be formatted properly to conform to JSON. You can try running your sitemap through a validator like https://jsonlint.com/

Example of correct regex:
