I would like to know if this possible to apply.
for example i have this table:

new_feed_dt regex_to_apply  expr_to_apply               
053021  | _(d+)        | date_format(to_date(new_feed_dt, 'yyyyMMdd'), 'yyyy-MM-dd')               
053022  | _(d+)        | date_format(to_date(new_feed_dt, 'yyyyMMdd'), 'yyyy-MM-dd')               
053023  | _(d+)        | date_format(to_date(new_feed_dt, 'yyyyMMdd'), 'yyyy-MM-dd')               
053024  | [a-zA-Z]+(d+) | date_format(to_date(new_feed_dt, 'MMddyyyy'), 'yyyy-MM-dd')              
053025  | DT(d+)       | date_format(to_date(new_feed_dt, 'MMddyy'), 'yyyy-MM-dd')             

I need to use this expr to apply column to the date column

example image:

I tried so far this but it didnt work.

df_with_regex.withColumn(
        'new_feed_dt',
        f.expr("expr_to_apply")
    )

how would you do it?

Thanks in advance
