Websocket Message Parser

[astrebaba31]

For example, let's say we receive a message like 42(5[1,2,3,4,5]) from a WebSocket. I want to extract the value 5 from within this message. It would be helpful if such a feature were available.

Hi @astrebaba31, you can do that using Set Variable under WebSocket Rules.

• Then
  • Set Variable
    • Use Message Value - Checked
    • Source Message Value - WebSocket Message
    • Source Value Type - Text
    • Use Regex Replace - Checked
    • Regex Pattern - \d+\((\d+)\[(\d+,?)*\]\)
    • Regex Replacement Text - $1
    • Destination Variable Source - <Your choice>
    • Destination Variable Name - <Your choice>

WebSocket Message gets you the value 42(5[1,2,3,4,5]) and the regex extracts the subvalue.
