I have a requirement where I have to fetch prefix in a text excluding right hand side digit pattern.

For ex: AB9T0005 should give me only AB9T

AB9T-K1A-0005 should give me only AB9T-K1A-

What I mean is prefix may include any input including numbers and other alpha numeric values.

With out using regular expression I will parse from right to left till I find non numeric value and will take substring of it.

I have used following regular expression \b(?<=.*)\d*\b but of no use?

It is failing for this input abc123

Can any one help me in this?

Thanks in Advance
