How to remove data in Robot Framework using regular expression pattern

Question

I'm want to extract few data without passing it directly like this,

    ${log_line}    Set Variable    {name:abc}[abc@xyz:(pg)]
    ${cleaned_log}    Remove string    ${log_line}    [abc@xyz:(pg)]
    Log ${cleaned_log}

Instead, trying below code with regular expression pattern. But it is not working as expected. Is there any other way? Inputs from anyone would be very helpful.. expected output- {name:abc}

    ${log_line}    Set Variable    {name:abc}[abc@xyz:(pq)]
    ${cleaned_log}    Replace string    ${log_line}    \[.*?\]    ${EMPTY}
    Log ${cleaned_log}

Answer 1

The keyword Replace String Using Regexp can be used instead

*** Test Cases ***
Replace using Regexp
    ${log_line}        Set Variable    {name:abc}[abc@xyz:(pg)]
    ${cleaned_log}     Remove String Using Regexp    ${log_line}    \\[.*?\]    ${EMPTY}
    Log                ${cleaned_log}
