Regex match everything up until sequence of characters -


i trying extract part of json message failing write correct regex.

biggest problem application writing (impala - big data query engine) contains bug preventing non-greedy operations using ?, therefore need different solution.

example

{"postcode":"abcdef","forename":"james","id":"{12}","surname":"townsend"}, {"postcode":"hijklm","forename":"toby","id":"{34}","surname":"taylor"}, {"surname":"reilly","postcode":"nopqrs","forename":"mike","id":"{56}"}

the data in format in 1 string (no line breaks) inside each "section" the data can in order.

i need use regex end part of message forename "toby"

{"postcode":"hijklm","forename":"toby","id":"{34}","surname":"taylor"}

currently have

{[^{]*"forename":"toby"[^}]*}

however doesn't work work, need match {" , "} start , end.

can please offer advice on how this?

thanks

escape leading/trailing curly brackets:

\{[^{]*"forename":"toby"([^}]|\}(?="))*\}(?!")

see live demo.
