Question

I have a problem with RegEx in java;

my line is :

CREATE CHAN:NAME=BTSM:1/BTS:2/TRX:5/CHAN:7,CHTYPE=TCHF_HLF,FHSYID=FHSY_0

and I want this :

content [0] = BTSM:1/BTS:2/TRX:5/CHAN:7
content [1] = CHTYPE
content [2] = TCHF_HLF
content [3] = FHSYID
content [4] = FHSY_0

I wrote this :

String[] content = value.split("^=/:|,|=|,$");

but it’s not work 🙁
so kindly inform me about that…
Thanks a lot …

Answer 1

String[] content = value.replaceFirst("^[^=]*=", "").split("[,=]");

should do what you want.

I don’t understand how you derived "^=/:|,|=|,$" so I can’t tell you where you went wrong, but here’s a breakdown of what it does.

^=/:

This is going to skip the string =/: if it occurs at the beginning and stick an empty string at the start of the results. Perhaps you wanted a character set. [=/:] is a character set that matches any occurence of one of those characters.

,

This will split on any comma.

=

This will split on any equals sign.

,$

This will skip a comma at the end of the input (or just before a newline at the end of input) and if skipped will stick an empty string on the end of the split result.
