Question

For the following strings, I am trying to extract ‘mainline’ if the string contains mainline, or the number at the end if it doesnt contain mainline. I am using Java.

Eg, for the following strings I want just the numbers at the end

Solaris10NBngp-bwm1.1.X     // want 1.1.x
Solaris10NBbytel2.0.0.0x    // want 2.0.0.0x
Solaris10NBbwm1.2.X         // want 1.2.X
Solaris10NBoam_bwm1.4.0.X   // want 1.4.0X
Solaris10NBoam1.7.X         // want 1.7.X

Mainline examples:

Solaris10NBngp-bwm_mainline // want mainline
LinuxNBdaypass_mainline     // want mainline
LinuxNBngp_mainline         // want mainline

Is this possible using regex, and if so, anybody know how to do it? 🙂

Answer 1

Solaris10NBngp-bwm1.1.X     // want 1.1.x 
Solaris10NBbytel2.0.0.0x    // want 2.0.0.0x 
Solaris10NBbwm1.2.X         // want 1.2.X 
Solaris10NBoam_bwm1.4.0.X   // want 1.4.0X 
Solaris10NBoam1.7.X         // want 1.7.X

For the above inputs,

expectedString = yourString.replaceAll("[^.]+(\\d+\\.)","$1");
