Regex match everything up until specific number + character sequence

Question

I am trying to match on product titles up until their pack size.

Examples:

• Glen 20 Disinfectant Spray Original Scent 300g
• Devondale 100% Pure Full Cream Long Life Milk 1l
• Maggi 2 Minute Instant Wholegrain Beef Noodles 5 Pack

To return:

• Glen 20 Disinfectant Spray Original Scent
• Devondale 100% Pure Full Cream Long Life Milk
• Maggi 2 Minute Instant Wholegrain Beef Noodles

Matching on numbers using [^0-9]* does not take into account names including numerical values.

Is there a [^0-9]* AND (g|l| Pack) combo i could use?

Answer 1

You could use the following regex pattern:

^.*(?=\s+\d+\w*(?: \w+)?$)

Demo

This regex pattern says to match:

^.*                      all content from the start
(?=\s+\d+\w*(?: \w+)?$)  until hitting a number with optional trailing
                         word characters, followed by space and optional unit,
                         at the end of the input
