Hey guys – I’m tearing my hair out trying to create a regular expression to match something like:
{TextOrNumber{MoreTextOrNumber}}
Note the matching number of open/close {}. Is this even possible?
Many thanks.
Historically, no. However, modern regular expressions aren’t actually regular and some allow such constructs:
(?R)recursively inserts the pattern again. Notice that not many regex engines support that (yet).
