I want to find a string like a DOI in a sentence and extract the result in a cell. I found the »regex« function in LibreOffice Calc (current Ver. 18.104.22.168) which tells me that it would exactly do what I want.
Foo bar doi: 10.1016/j.cmpb.2018.09.006 baar foooo
My regex in python is:
and suits me well in a python script (it matches exactly the doi number without the »doi« string, which is intended).
But the »regex« function refuses this regex. The documentation mentions the ICU Regex Expressions, where I can't find any issues comparing with my regex.
Do I miss something? Which »regex dialect« is applicable for LibreOffice?
