Incorrect escaping of z node values

[maratische]

our zookeeper contains value with <>
for example:
{"regexp" : "\\*([0-9]+)(\\*(?<subscribeShortCode>[0-9]+))?#","caseSensitivity" : "false"}
On zk-web we see it like
{"regexp" : "\\*([0-9]+)(\\*(?[0-9]+))?#","caseSensitivity" : "false"}

its a problem
