extractx

To extract a string from a given text using a regular expression
With this function, you can extract the first match of a search string in a text.
Instead of simple strings as a search pattern, you can use regular expressions (regex). That means you have much more possibilities for text analysis.
You could use this function for example to extract relevant information from imported data.
Using regular expressions might need some extra research. We recommend checking regular expressions on https://regex101.com/ (external link).
