Matching a complex expression in python regex -

i have create unique textual marker in document using python 2.7, following function:

def build_textual_marker(number, id):     return "[xxxcixxx[[_'" + str(number) + "'] [_'" + id + "']]xxxcixxx]"

the output looks : [xxxcixxx[[_'1'] [_'24']]xxxcixxx]

and have catch occurrence of expression in document. ended following regular expression seems not working fine:

marker_regex = "\[xxxcixxx\[(\[_*?\])\s(\[_*?\])\]xxxcixxx\]"

i wondering how should write correct regex in case?

try using

\[xxxcixxx\[\[_'.*?'\] \[_'.*?'\]\]xxxcixxx\]
