Regular Expression Extractor is usually much faster compared to other extractors like XPath, JSON etc - Check this site for the comparison.

Lets assume we are trying to get the value of all the theme ids from the JSON. Add a Regular Expression Extractor and update the details as shown here.

You need a reference name to store the value found
The pattern to check
Template used to create a string from the matches found
-1 for all matches, 0 for random, 1 for first ..etc

<variable>_matchNr will give the total matches
theme.id_1 will return the first match which is 27
theme.id_2 will return the second match which is 28

More details and examples are here.
