ruby - 如何将正则表达式与 Nokogiri::XML::Text 对象一起使用？

Question

我有一个名为这些对象的人的数组：

Nokogiri::XML::Text:0x3fe41985e69c "CEO, Company_1"
Nokogiri::XML::Text:0x3fe4194dab74 "COO, Company_2 "
Nokogiri::XML::Text:0x3fe4195eb414 "CFO, Company_3"

我想在“，”处拆分对象，所以我尝试做这样的事情：

companies = people.each do | company | 
  company.inner_text.match("/, (.*)/")
end

和：

occupations = people.each do | occupation | 
  occupation.inner_text.match("/(.*),/") 
end

match似乎没有从对象中提取我想要的值。我检查了 rubular.com，它应该可以工作，但我得到的字符串与我输入的字符串相同： 何时应该将其分开，"CEO, Company_1"以便.occupations = [CEO, COO, CFO]companies = [Company_1, Company_2, Company_3]

如何拆分这些对象？

Answer 1

怎么不split发文？

require 'nokogiri'

xml = '<x>
<people>CEO, Company_1</people>
<people>COO, Company_2</people>
<people>CFO, Company_3</people>
</x>
'

doc = Nokogiri::XML(xml)
people = doc.search('people')
companies = people.map do |company| 
  company.text.split(',')
end

pp companies

=> [["CEO", " Company_1"], ["COO", " Company_2"], ["CFO", " Company_3"]]

如果您想摆脱公司之前的领先空间，请使用：

companies = people.map do |company| 
  company.text.split(/,\s*/)
end
=> [["CEO", "Company_1"], ["COO", "Company_2"], ["CFO", "Company_3"]]

或者：

companies = people.map do |company| 
  company.text.split(',').map(&:lstrip)
end
=> [["CEO", "Company_1"], ["COO", "Company_2"], ["CFO", "Company_3"]]

或使用map{ |s| s.sub(/^\s+/, '') }代替lstrip.
