[Python] Validate the pattern of an xml file's name

i working on a robot framework project. The target of the test is to evaluate if the xml file name respect the specific pattern.

First attempt:

*** Variables ***
${FILENAME} 222222_XT211-D(SM211)_Scenario_SetFrameCounter_result_6157_ok_02112024-172720.xml
${PATTERN} ^\d{6}_XT\d{3}-D\(SM\d{3}\)_Scenario_SetFrameCounter_result_\d{4}_ok_\d{8}-\d{6}\.xml$

*** Test Cases ***
Validate Xml Filename Structure
Should Match ${FILENAME} ${PATTERN}


Second attempt:

*** Variables ***
${FILENAME} 222222_XT211-D(SM211)_Scenario_SetFrameCounter_result_6157_ok_02112024-172720.xml
${PATTERN} ^\d{6}_XT\d{3}-D\(SM\d{3}\)_Scenario_SetFrameCounter_result_\d{4}_ok_\d{8}-\d{6}\.xml$

*** Test Cases ***
Validate Xml Filename Structure
Should Match Rexep ${FILENAME} ${PATTERN}


But as result, it always fails and i don't know exactly where's the fail.: This is what i got as result. '222222_XT211-D(SM211)_Scenario_SetFrameCounter_result_6157_ok_02112024-172720.xml' does not match '^d{6}_XTd{3}-D(SMd{3})_Scenario_SetFrameCounter_result_d{4}_ok_d{8}-d{6}.xml$'
