Regex get everything between letter word and number

I have example string like

Я, Филиппова Яна Сергеевна, 17.09.2001 года рождения

I need to extract everything between character Я, (always fixed) and before , 17.09.2001 ( not fixed, can be other date)

I expect Филиппова Яна Сергеевна as output excluding commas
I tried something like Я,(.*)17.09.2001 to match general pattern but it did not worked out

>Solution :

You can use the lookaround syntax:

(?<=Я, )[^,]+(?=, \d+\.\d+\.\d+)

How this works:

• (?<=Я, ) positive lookbehind to match if there is a literal Я, (including whitespace) on the left
• [^,]+ one or more characters that are not commas
• (?=, \d+\.\d+\.\d+) positive lookahead to match if there is a date like string on the right side
