xml 屬性的 Ruby 正則表達式

Question

我正在嘗試為 fluentbit 解析器創建一個 regx 表達式，但不確定如何從字符串中刪除特定字符

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

以上是我作為字符串的輸入，我想從中制作多個鍵。

預期 output：

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

請問我怎樣才能做到這一點？

Answer 1

當然，您可以編寫自己的解析器，但使用 Nokogiri 可能更舒服？

require 'nokogiri'

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

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

Answer 2

嘗試這個：

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\""}
