REPLACE_REGEXPR function in Hana

Hello Experts,

Below is the logic for regexp_replace from source DB.

Can you please help how to achieve this in Hana Scipt.

   regexp_replace(field1,'^[^|]*\|([^|]*).*$','\1')   as channel_1,

   regexp_replace(field1,'^([^|]*\|){2}([^|]*).*$','\2')  as num_channel_1,

sample data format for field1 as below

123123|444|555|6666|77|88

Thanks,

Kris
