Ruby regx for xml attributes-CodePudding

i am trying to create a regx expression for fluentbit parser and not sure how to drop specific characters from a string

<testsuite name="Activity moved" tests="1" errors="0" failures="0" skipped="0" time="151.109" timestamp="2022-09-05T16:22:53.184000">

Above is the input which is i have as a string and i want to make multiple keys out of it.

expected output:

name: Activity moved
tests: 1
errors: 0
failures: 0
skipped: 0
timestamp: 2022-09-05T16:22:53.184000

How can i achieve this please?

try this:

str = "<testsuite name=\"Activity moved\" tests=\"1\" errors=\"0\" failures=\"0\" skipped=\"0\" time=\"151.109\" timestamp=\"2022-09-05T16:22:53.184000\">"

regexp = /\w*=".*?"/ # there's your regexp

str.scan(regexp).inject({}) do |h,m| 
  k,v=m.split("=")
  h[k]=v
  h
} # and this is how you make the requested hash
# => {"name"=>"\"Activity moved\"", "tests"=>"\"1\"", "errors"=>"\"0\"", "failures"=>"\"0\"", "skipped"=>"\"0\"", "time"=>"\"151.109\"", "timestamp"=>"\"2022-09-05T16:22:53.184000\""}

Of course you can write your own parser but may be it's more comfortable to use Nokogiri?

require 'nokogiri'

doc = Nokogiri::XML(File.open("your.file", &:read))

puts doc.at("testsuite").attributes.map { |name, value| "#{name}: #{value}" }
