java - Regex for matching alternating sequences -

-

i'm working in java , having trouble matching repeated sequence. i'd match like:

a.b.c.d.e.f.g.

and able extract text between delimiters (e.g. return abcdefg) delimiter can multiple non-word characters , text can multiple word characters. here regex far:

([\\w]+([\\w]+)(?:[\\w]+\2)*)

(doesn't work)

i had intended delimiter in group 2 regex , use replaceall on group 1 exchange delimiter empty string giving me text only. delimiter, cannot text.

thanks help!

replace (\w+)(\w+|$) $1. make sure global flag turned on.

it replaces sequence of word chars followed sequence of non-word-chars or end-of-line sequence of words.

string line = "am.$#%^ar.$#%^gho.$#%^sh"; line = line.replaceall("(\\w+)(\\w+|$)", "$1"); system.out.println(line);//prints name

i'm trying load particular private key encoded in binary der format ( pkcs#8 ) ruby. however, openssl::pkey won't recognize it. can make work doing console work , transforming pem so: openssl pkcs8 -inform der -in file.key -passin pass:xxxxxxxx >private_key.pem after this, key can correctly read. however, since whole process done in memory instead of writing , reading files. so question is: possible load private keys binary encoded der format ruby/openssl? thank time, fernando yes, can indirectly load pkcs#8 der-encoded private keys using ruby openssl. openssl::pkey::rsa.new handle pem-formatted pkcs#8, easy read binary der , convert pem-formatted string , load string. for example, these der-encoded private keys: $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -nocrypt -out pkcs8.key $ openssl genrsa | openssl pkcs8 -topk8 -outform der \ -v2 des3 -passout pass:secret -out pkcs8_des3.key you can this: require 'open...
