Question

I have a string like this one:

{{foobar
| option1 = foo
| option2 = foo
| <!-- more options -->
| something = xxx
| thisoption = xxx
| <!-- more options -->
}}

I want it to be “thisoption = xxx” to be replaced by “thisoption = abc”. It shouldn’t matchany of the following:

{{foobar
| option1 = foo
| option2 = foo
| thisoption = xyz
}}

{{foobar
| option1 = foo
| option2 = foo
}}
{{someotherthing
| thisoption = xxx
}}

How can I do this?

Answer 1

To answer my own question, this seemed to do the trick:

re.sub(r"(\{\{foobar[^\}]*)thisoption ?= ?xxx", r"\1thisoption = abc", string)

Thanks to everyone who helped out!
