I have a question how to extract a substring.
Here an example string:
{{from,005021889988,,Amt},{setup-from,66,,},{alert-to,66,ConTeach Zentrale,ConTeach Zentrale},{conn-to,66,ConTeach Zentrale,ConTeach Zentrale},{transfer-to,10,kb,Kai Büsing},{conn-to,66,ConTeach Zentrale,ConTeach Zentrale {disc-to,,,},{rel-from,66,ConTeach Zentrale,ConTeach Zentrale}}
The goal is to extract '66,ConTeach Zentrale,ConTeach Zentrale' between '{conn-to,' and '},'
Any ideas?

You can use the function
substring()
with a regular expression. But you need to define your requirements exactly. Like markp commented, there is ambiguity with multiple matches.The part between parentheses is returned. This returns the first match, and the non-greedy quantifier
*?
prefers the shortest match.
