Weird, it seems some escaping characters were left out when I copy/pasted from RegExr. (That tool is invaluable!)
To isolate what's between your tags you need to inspect capture group #2 as seen here :
However, Construct implementation of Regex is a bit lacking in that regard, you can't inspect capture groups while in global mode. You need to rexecute the Regex on each match individually without the "g" flag, which is quite a bother.
